[0079] Figure 3 is a schematic diagram of a first document page provided in Example 1 of the present application. Figure 3 As shown, the first document page may be a document page displayed on a computer, and a plurality of page elements may be displayed in the first document page, wherein the page elements displayed in the title bar 301 of the first document page may include a document title 302, an avatar 303 of the first user, and a user avatar display area 304. The avatar 303 of the first user may be an avatar of the current user, and the user avatar display area 304 may display an avatar of the user who has opened the current document. The avatars displayed in the user avatar display area 304 may include the avatar 303 of the first user and the avatar of the second user, and the second user may be a user who has opened the current document other than the first user. In the case where the number of users who have opened the current document is large, the user avatar display area 304 may be displayed in a folded form in the title bar 301. For example, the document title 302 is "XX Document", the avatar 303 of the first user is "Current User", and the user avatar display area 304 may display the avatar of User 1, the avatar of User 2, and the number of avatars of users who have viewed the current document.

[0080] The page elements displayed in the title bar 301 may also include a control 307 for cancelling the collapsed display. By clicking the control 307 for cancelling the collapsed display, a user basic information list 305 may be displayed on the first document page. The basic information list 305 may display the avatars and user names of all users currently viewing the document.

[0082] Figure 4 is a schematic diagram of a first document page provided in Example 2 of the present application. Figure 4 As shown, the first document page may be a document page displayed on a mobile phone, and multiple page elements may be displayed in the first document page, including a user avatar display area 401, which may display the avatar of the user who has opened the current document (the avatar of user 1), the avatar of user 2, and the number of avatars of users who have viewed the current document, wherein in the user avatar display area 401, the first user avatar may also be the avatar of the first user, that is, the avatar of the current user. The page elements also include a control 402 for cancelling the folding display, and by clicking the control 402 for cancelling the folding display, a user basic information list 403 may be displayed on the first document page.

[0083] It should be noted that the page elements contained in the first document page displayed on the mobile phone and the first document page displayed on the computer can be the same or similar. Figure 4 The user avatar display area 401, the control 402 for cancelling the folding display, and the user basic information list 403 are already in Figure 3 The details are described in detail in the chapter and I will not go into details here.

[0084] In an exemplary embodiment of the present application, the page elements of the first document page further include hidden controls. Wherein, obtaining the first document page based on different display modes in the document page may include but is not limited to cases one to three.

[0085] In case 1, the hidden control is directly displayed in the first document interface.

[0086] Figure 5 Schematic diagram of a first document page showing hidden controls provided in the first embodiment of the present application. Figure 5As shown, the designated area of ​​the first document page can display a hidden control, for example, a hidden control 503, i.e., a "stealth view" control, is displayed in the title bar of the first document page. The designated area of ​​the first document page can be set based on user habits and actual conditions, and this application does not limit it.

[0087] Figure 6 is a schematic diagram of a first document page showing hidden controls provided in the second embodiment of the present application. Figure 6 As shown, the designated area of ​​the first document page can display a hidden control, for example, a hidden control 603, i.e., a "stealth viewing" control, is displayed in the upper area of ​​the first document page. The designated area of ​​the first document page can be set based on user habits and actual conditions, and this application does not limit it.

[0088] In case 2, when the page elements displayed in the first document page include a user basic information list, the hidden control is displayed in the user basic information list.

[0089] In the first embodiment of the present application, combined with Figure 5 , the page elements displayed in the first document page include a control 504 for canceling the folding display, by which the user basic information list 501 can be displayed in the first document page, and a hidden control 502 can be displayed in the user basic information list 501. Taking the current user as user 1 as an example, a hidden control 502, i.e., a "turn on incognito viewing" control, can be displayed in the area corresponding to the basic information of user 1 in the user basic information list 501.

[0090] In the second embodiment of the present application, combined with Figure 6 , the page elements displayed in the first document page include a control 604 for canceling the folding display, by which the user basic information list 601 can be displayed in the first document page, and a hidden control 602 can be displayed in the user basic information list 601. Taking the current user as user 1 as an example, a hidden control 602, i.e., a "turn on incognito viewing" control, can be displayed in the area corresponding to the basic information of user 1 in the user basic information list 601.

[0091] Case three, when the page elements displayed on the first document page include a menu control, and when the menu control is triggered, a menu list page element is displayed on the first document page, and the hidden control is displayed in the menu list page element.

[0092] Figure 7 Schematic diagram of another first document page showing hidden controls provided in the first embodiment of the present application. Figure 7As shown, the page elements displayed on the first document page include a menu control 701. When the menu control 701 is triggered, a menu list page element 702 may be displayed on the first document page, and a hidden control 703 may be displayed in the menu list page element 702. The menu list page element 702 may also display other functional controls or document information. For example, the document information may include the document owner and the creation time of the document. Other functional controls may include, but are not limited to: exporting a document, generating a copy, revision history, printing, opening a document like, etc., and corresponding operations may be performed on the document through the triggering operation of other functional controls.

[0093] Figure 8 is a schematic diagram of another first document page showing hidden controls provided in the second embodiment of the present application. Figure 8 As shown, the page elements displayed on the first document page include a menu control 801. When the menu control 801 is triggered, a menu list page element 802 may be displayed on the first document page. The menu list page element 802 may include a hidden control 803. The menu list page element 802 may also display other functional controls or document information. For example, the document information may include the document creator and the name of the document. Other functional controls may include but are not limited to: exporting documents, making copies, making pictures, sending to computers, permissions, adding to files, renaming, etc. Through the triggering operation of other functional controls, corresponding operations may be performed on the document.

[0094] It should be noted that the different ways of displaying and hiding controls to obtain the first document page in this application are exemplary descriptions, and other ways of displaying and hiding controls can also be used to obtain the first document page, and this application does not limit this. In addition, the first document page can also include other page elements, and this application only provides exemplary descriptions of some page elements.

[0095] In step 220, in response to the triggering operation of the hidden control, the configuration conditions associated with multiple page elements in the first document page are detected to obtain detection results. The configuration conditions associated with any page element include variable parameters and operations on the variable parameters. The variable parameters are dynamically changing parameters corresponding to any page element. The operations on the variable parameters are used to express the operations corresponding to the conditions that the variable parameters need to meet.

[0096] In an exemplary embodiment of the present application, multiple page elements in a first document page are associated with configuration conditions. Based on different user operations, the parameters of the page elements in the first document page are changed accordingly. The configuration conditions and the parameters of the page elements are detected by calling an object to obtain a detection result. In a subsequent process, the display state of the page elements can be dynamically changed using the detection result. For example, the page element can be changed from a display state to a hidden state.

[0097] Before detecting the configuration conditions associated with the page elements in the first document page based on the calling object, it is necessary to determine the calling object. The process of determining the calling object may include steps 221 to 224.

[0098] In step 221, an expression string is determined based on configuration conditions associated with a plurality of page elements of the first document page.

[0099] Exemplarily, a plurality of page elements may be displayed in the first document page, each of which may be associated with one configuration condition or with multiple configuration conditions. The present application takes the association of a page element with multiple configuration conditions as an example for explanation, that is, the expression string is determined by multiple configuration conditions. The configuration conditions include variable parameters and operations on the variable parameters, wherein the variable parameters are dynamically changing parameters corresponding to the page elements, and the operations on the variable parameters are used to express the operations corresponding to the conditions that the variable parameters need to satisfy, and the operations on the variable parameters include at least one of basic operations, function operations, variable assignments, or symbol operations.

[0100] In an exemplary embodiment of the present application, the expression string may include multiple substrings, and the number of substrings may be the same as the number of configuration conditions associated with the page elements. For example, the substrings correspond one to one with the configuration conditions associated with the page elements.

[0101] Exemplarily, the page element in the first document page may include a cursor selected area, and the configuration conditions associated with the cursor selected area may be document state configuration conditions, hidden control state configuration conditions, and selected area configuration conditions, wherein when the document is in a non-editable state, the hidden control is in a triggered state, and the area range selected by clicking is greater than or equal to 1, the cursor may be hidden, and 1 may be a range of 1 cell. The variable parameters in the configuration conditions may include the document editing state (canEdit), the state of the hidden control (toggle), and the selected area range (selectRange), and the operations of the variable parameters may include equal to (==), greater than or equal to (>=), and logical AND operations (&&). In summary, the expression string "when" corresponding to the configuration condition of the page element cursor selected area may be "when": "canEdit==false&&toggle==true&&selectRange>=1", wherein "canEdit==false" indicates that the document is in a non-editable state, "toggle==true" indicates that the hidden control is in a triggered state, and "selectRange>=1" indicates that the area range selected by the cursor is greater than or equal to 1.

[0102] It should be noted that the expression strings corresponding to different page elements can be the same or different. The expression strings can be determined based on the actual configuration conditions of the page elements. The expression strings may include but are not limited to variables, constants, regular expressions, congruent operations, inequality operations, logical operations (AND, OR, NOT), basic operations (addition, subtraction, multiplication, division, remainder), function calls, variable assignments, etc. This application does not limit the content of the expression strings.

[0103] In step 222, the expression character string is segmented based on the reference rule to obtain a segmentation result.

[0104] Exemplarily, after obtaining the expression string, the expression string can be segmented based on the reference rule, the expression string can be divided into multiple substrings and the priority corresponding to the substrings can be determined. Wherein, the reference rule can include at least one of a grammar rule or a priority rule, the grammar rule can represent the grammatical structure that the substring needs to satisfy, and the priority rule can determine the execution order between different logical operators. The substring can include a key, an operation escape type, and a value, or the substring can include a key and a value.

[0105] For example, the expression string is processed by using position index (indexOf) and split (split) to divide the expression string into multiple substrings. The expression string can be divided into three substrings by logical AND operation (&&) based on the reference rule, namely "canEdit==false", "toggle==true" and "selectRange>=1" through "&&"; then the substrings are divided into key, type, value or key, value based on the operator contained in each substring. For example, the keys in "canEdit==false" and "toggle==true" are canEdit and toggle, and the values ​​are false and true respectively; the key in selectRange>=1 is selectRange, the type is>=, and the value is 1.

[0106] The present application performs word segmentation processing on the expression string by referring to the rules, and divides the expression string into smaller and easier to understand substrings, which helps to form a tree structure corresponding to the expression string later. In addition, dividing the expression string into substrings makes it easier to detect and correct errors in the expression string, which can improve the accuracy of the expression string to a certain extent.

[0107] In step 223, the tree structure corresponding to the expression character string is determined based on the word segmentation result.

[0108] Fig. 9 is a schematic diagram of a tree structure provided in an embodiment of the present application. Fig. 9 As shown, the expression string can be used as the root node of the tree structure. Based on the reference rule, the logical AND operation (&&) is used as the first-level node of the tree structure. After passing the first-level node, the expression string can be divided into 3 substrings, and then the operators (== and >=) in the substrings are used as the second-level nodes of the tree structure. The variable parameters in the substrings and the parameters corresponding to the variable parameters in the first document page can be used as the third-level nodes of the tree structure (canEdit, false, toggle, true, selectRange and 1).

[0109] It should be noted that the tree structure in this application is an exemplary description. Different expression strings or the same expression strings can obtain different tree structures if they are segmented based on different reference rules. This application does not limit the form of the tree structure.

[0110] In step 224, the calling object is determined based on the operation escape type and the tree structure. The operation escape type is determined based on the operation type mapping table. The operation type mapping table is used to reflect the relationship between the operation type and the operation escape type.

[0111] In an exemplary embodiment of the present application, the operation escape type can be determined based on an operation type mapping table, and the operation type mapping table is used to reflect the relationship between the operation type and the operation escape type. Table 1 is a mapping table between the operation type and the operation escape type. Among them, the operation type (ContextKey) represents the type of operation that can be performed on the key (key) or substring in the substring, and the operation escape type (type) can be set to the number corresponding to the operator. For example, the operator of ContextKey can be Equals (equal to, ==), And (logical AND operation, &&) and GreaterOrEquals (greater than or equal to, >=); the corresponding expression escape (type) can be 4, 6 and 12.

[0112] Table 1

[0113] ContextKey type ContextKey type False 0 Regex 7 True 1 NotRegex 8 Defined 2 Or 9 Defined 3 Greater 10 Equals 4 Less 11 NotEquals 5 GreaterOrEquals 12 And 6 LessOrEquals 13

[0114] It should be noted that ContextKey may also include other operators that can be executed on a key or a substring. Table 1 only provides an exemplary description, and this application does not limit this. In addition, the application provides an exemplary description of the form of the operation escape type. The mapping table between the operation type and the operation escape type can be set based on the user's programming habits, and this application does not limit this.

[0115] Exemplarily, the calling object can be determined based on the operation escape type and the tree structure. Fig. 9 The tree structure and operation type mapping table can determine the expression string contained in the call object. The content of some call objects is as follows:

[0116]

[0117]

[0118] In an exemplary embodiment of the present application, the calling object may further include page element identification information, and different page elements correspond to different page element identification information, that is, the page element and the page element identification information are one-to-one corresponding. The page element can be associated with the calling object through the page element identification information. The page element identification information may include an identity document (ID) of the page element, and optionally, the page element identification information may also include but is not limited to a class name or a tag name corresponding to the page element.

[0119] In an exemplary embodiment of the present application, after determining the call object, the call object can also be stored, for example, the call object is stored in an object database (MenuRegistry). By storing the call object in the object database, the use of the call object in subsequent processes can be facilitated.

[0120] This application determines the expression string through the configuration conditions associated with the page element, and implements the state judgment of the page element for the expression string corresponding to the page element, which can more conveniently determine the target element based on the calculation result of the string. The tree structure is determined for the word segmentation result of the expression string, and the calling object is determined based on the operation escape type and the tree structure, which can improve the flexibility of processing the expression string contained in the calling object.

[0121] In an exemplary embodiment of the present application, after determining the calling object, the server receives a trigger signal for hiding the control, for example, the server receives a trigger signal for hiding the control from the terminal of the first user, that is, the server receives an invisibility request from the first user. The server will send a calling object to the terminal for viewing or editing the document. After receiving the calling object, the terminal for viewing or editing the document detects page elements in the document page based on the calling object.

[0122] Exemplarily, a terminal for viewing or editing a document may receive a call object, the call object including an expression string, the expression string including at least one substring, the substring corresponding one-to-one to a configuration condition associated with a page element; the expression string is parsed based on a string parser to obtain a detection result.

[0123] In an exemplary embodiment of the present application, a terminal for viewing or editing a document is installed with a string parser. After receiving a call object, the terminal for viewing or editing a document parses the expression string contained in the call object based on the string parser to obtain a detection result. The process of parsing the expression string based on the string parser to obtain a detection result may include steps 225 to 228.

[0124] In step 225, the variable parameters are determined based on the configuration condition that the expression string contains a substring corresponding to the substring.

[0125] Exemplarily, continuing to take the expression string "when" as an example, the variable parameters in the configuration condition corresponding to the expression string "when" may include the document editing state (canEdit), the state of the hidden control (toggle), and the selected area range (selectRange). It should be noted that the relevant content of the expression string has been described in step 221, and will not be repeated here.

[0126] In step 226, a parameter value corresponding to the variable parameter is obtained in the first document page.

[0127] In an exemplary embodiment of the present application, the terminal of the second user obtains the parameter value corresponding to the variable parameter in the first document page based on the variable parameter. For example, the editing state of the document is obtained. If the document is in the editing state, the parameter value corresponding to the variable parameter can be determined to be true. If the document is in a non-editable state, the parameter value corresponding to the variable parameter can be determined to be false; the state of the hidden control is obtained. If the hidden control is in a triggered state, the parameter value corresponding to the variable parameter can be determined to be true. If the hidden control is in a non-triggered state, the parameter value corresponding to the variable parameter can be determined to be false; the selected area range is obtained. If the second user selects a certain area range in the first document page, the actual value of the area range of the parameter value corresponding to the variable parameter can be determined. If the second user does not make a selection in the first document page, the parameter value corresponding to the variable parameter can be determined to be 0.

[0128] In step 227, a first reference area is determined in the first document page based on the parameter value corresponding to the variable parameter and the expression string, where the first reference area is an area where the expression string is executed.

[0129] Exemplarily, the expression string may include a variable parameter, based on which a parameter value corresponding to the variable parameter may be determined on the first document page, and the first reference area may be determined using the variable parameter and the acquisition position or action position of the parameter value corresponding to the variable parameter on the first document page. For example, the first reference area includes an area of ​​a selected area range.

[0130] In step 228, within the first reference area, the expression string corresponding to the page element is parsed based on the string parser to obtain a detection result.

[0131] Exemplarily, in the first reference area, the expression string corresponding to the page element is parsed using a string parser (eval). For example, a terminal that views or edits a document may execute the following program to parse the expression string:

[0132] if(eval(menu.when))

[0133] {return true||false;}

[0134] After the expression string is parsed, the detection result can be obtained, which can be expressed in the form of a Boolean value, that is, true or false. The detection result of each page element or the detection result of a specified page element can be obtained by calling an object on the page elements in the first document page.

[0135] It should be noted that the types of string parsers in the parsing program of the present application are exemplary illustrations, and other types of string parsers may also be used to parse expression strings, and the present application does not impose any restrictions on this.

[0136] In an exemplary embodiment of the present application, as the user views or edits the document page, the parameter value corresponding to the variable parameter in the configuration condition corresponding to the page element in the document page also changes accordingly. After the parameter value corresponding to the variable parameter in the configuration condition corresponding to the page element of the document page changes, the changed parameter can also be sent to the specified object (context object) based on the first key interface (setValue), and in the expression string parsing process, the changed parameter in the specified object can be directly obtained based on the second key interface (getValue). That is, when the user is viewing the document, after the parameter value corresponding to the variable parameter in the configuration condition corresponding to the page element of the document page changes, the terminal of other users can directly obtain the changed parameter through the key interface and the specified object, which improves the consistency of data acquisition, and the user's terminal can update the corresponding page element in the document page based on the changed parameter, which can improve the isolation between the page elements in the document page to a certain extent.

[0137] In step 230, a target element is determined based on the detection result, where the target element is a page element to be hidden among the page elements.

[0138] In an exemplary embodiment of the present application, a target element is determined in a page element based on a detection result, wherein the result corresponding to the page element is true or false. For example, a page element with a detection result of true is determined as a target element, and the target element is an element that needs to be hidden in a document page of a second user in a subsequent process.

[0139] Exemplarily, the target element may include at least one of user basic information or user behavior information, the user basic information may include at least one of a user name or a user avatar, and the user behavior information may include at least one of cell selection information, text selection information, cursor movement information, or viewing trace information.

[0140] Combination Figure 3 The user basic information may include the avatars and user names of all users currently viewing the document in the user avatar display area 304 and the basic information list 305. It should be noted that the user basic information in this application is an exemplary description, and the user basic information may also include other information that can indicate the identity of the user, and this application does not limit this.

[0141] For example, the user behavior information includes cell selection information. When the first user selects a cell in the document, the display state of the cell changes or at least one of the user names of the selected cell is displayed around the cell. For example, the change in the display state of the cell may change the color of the cell border. The cell selection information may include at least one of the display state of the cell or the user name of the selected cell. Among them, the text selection information and the cursor movement information are similar to the contents of the cell selection information, and are not described in detail here.

[0142] Exemplarily, when a user views or modifies a document, the background document log will record the user's operations. The viewing trace information may include relevant information recorded in the document log. The relevant information may include but is not limited to the name of the user who views or edits the document, the time of the document operation, and the content of the document operation.

[0143] It should be noted that the content of the target element in this application is an exemplary description, and the target element can also be modified based on actual conditions, and this application does not impose any restrictions on this.

[0144] In step 240, a second document page is displayed, where the second document page is obtained by hiding the target element in the first document page.

[0145] In an exemplary embodiment of the present application, after determining the target element, the target element in the first document page may be hidden to obtain a second document page. The target element is taken as a user name and a user avatar as an example for explanation.

[0146] Exemplarily, in the first document page, the target element of the first user is hidden or the hidden element corresponding to the target element of the first user is displayed to obtain the second document page, the first user is the user currently viewing the document incognito mode, and the hidden element is obtained by removing the target information based on the target element, and the target information is the information to be hidden contained in the target element of the first user. Among them, the target information can be information representing the identity of the user, that is, the information to be hidden in the second document page, and the target information includes but is not limited to user avatar information and user name information. This application is described by taking the target information as user avatar information and user name information as an example.

[0147] Fig.10 Schematic diagram of a second document page of a first user provided in Embodiment 1 of the present application. Fig.10As shown, when the first user is in the invisible state, the user avatar display area 1001 can display the invisible user-specific avatar of the first user in the invisible state, and the user avatar display area 1001 can display the avatar of the user in the non-invisible state, for example, User 2. The invisible user-specific avatar and the invisible user-specific name of the first user can be displayed in the basic information list 1002. For example, the name of the first user can be "Invisible User", and the invisible user-specific avatar can be the system default avatar. The basic information list 1002 can also display the status of the first user (current user). For example, the current user (I) is an invisible user, and the status of the current user can be displayed as "Invisible". In addition, the basic information list 1002 can also display basic information of other users who view or edit the current document. For example, other users who view or edit the current document include User 2, User 3, User 4, User 5...

[0148] Optionally, the second document page may further display first prompt information 1003, where the first prompt information is used to prompt the first user that the first user is viewing the document in stealth mode. For example, the content of the first prompt information is "viewing the current document in stealth mode".

[0149] Exemplarily, the page element of the second document page may further include a close hidden control, and in response to a trigger operation of closing the hidden control, the target element is displayed in the second document page. Fig.10 , a close hidden control, namely “close invisible view”, may be displayed in the relevant area of ​​the current user in the basic information list 1002. The first user may change the current invisible state into a non-invisible state by closing the hidden control.

[0150] Fig.11 Schematic diagram of a second document page of a first user provided in Embodiment 2 of the present application. Fig.11 As shown, when the first user is in the invisible state, the user avatar display area 1101 can display the invisible user-specific avatar of the first user in the invisible state, that is, the user avatar with the hidden character, and the basic information list 1102 can display the invisible user-specific avatar, the invisible user-specific name and the current user's status. Optionally, the first prompt information 1103 can also be displayed in the second document page.

[0151] Among them, the user avatar display area 1101, the basic information list 1102 and the first prompt information 1103 are similar to the relevant contents of the first embodiment and are not described in detail here.

[0152] In an exemplary embodiment of the present application, when the first user is in the invisible state, the target element of the first user can also be deleted in the second document page. For example, the current second document display page displays the avatars of 66 users who are viewing or editing the document, and the basic information list displays 66 user avatars and user names. When one of the users changes from a non-invisible state to an invisible state, the second document display page can display the avatars of 65 users who are viewing or editing the document, and the basic information list displays 65 user avatars and user names.

[0153] It should be noted that the method of hiding the target element in this application is an exemplary description, and other methods can also be used to hide the target element, and this application does not limit this.

[0154] In an exemplary embodiment of the present application, when the first user changes from a non-invisible state to an invisible state, the server may also synchronize the first user's invisible information to a second user, where the second user is a user other than the first user who is viewing or editing a document.

[0155] In the case that the second document page is the second document page of the second user, the target element of the first user is not displayed in the second document page or a hidden element corresponding to the target element of the first user is displayed.

[0156] Exemplarily, after the first user turns on the invisible view, the server synchronizes the information of the first user's invisible state to the second user's terminal, and the second document page of the second user's terminal does not display the first user's target element or displays the hidden element corresponding to the first user's target element. Among them, the first user's basic user information and user behavior information in the second document page of the second user will be hidden. For example, the first user's avatar in the second document page of the second user is a special avatar for invisible users, the name is invisible user, and the first user's cell selection operation, cursor movement, and text selection operation are not displayed.

[0157] Optionally, in the background document log corresponding to the second document page of the second user, the viewing trace information of the first user may also be hidden or deleted.

[0158] This application is explained by taking the hidden element corresponding to the target element of the first user displayed in the second document page as an example. Fig.12 Schematic diagram of a second document page of a second user provided in Embodiment 1 of the present application. Fig.12As shown, the user avatar display area 1201 can display the invisible user-specific avatars of multiple first users in the invisible state, and the user avatar display area 1201 can display the avatars of users in the non-invisible state (not shown in the figure). The basic information list 1202 can display the invisible user-specific avatar and the invisible user-specific name of the first user. The basic information list 1202 can also display the status of the second user (current user). For example, the current user (I) is a non-invisible user. When the second user has the invisible permission, the invisible control can also be displayed in the relevant area of ​​the second user in the basic information list 1202, that is, "Turn on invisible viewing", to remind the current user that the current document can be viewed in stealth mode. In addition, the basic information list 1202 can also display other basic information of the second user who views or edits the current document. For example, the second user also includes user 4, user 5...

[0159] Fig.13 Schematic diagram of a second document page of a second user provided in Embodiment 2 of the present application. Fig.13 As shown, the user avatar display area 1301 can display the invisible user-specific avatars of multiple first users in the invisible state, that is, the user avatars with hidden characters, and the user avatar display area 1301 can display the avatars of users in the non-invisible state (not shown in the figure). The basic information list 1302 can display the invisible user-specific avatar and invisible user-specific name of the first user. The basic information list 1302 can also display the status of the second user (current user). For example, the current user (I) is a non-invisible user. When the second user has the invisible permission, the invisible control can also be displayed in the relevant area of ​​the second user in the basic information list 1302, that is, "turn on invisible view", which is used to remind the current user that the current document can be viewed invisibly. In addition, the basic information list 1302 can also display other second user basic information that views or edits the current document. For example, the second user also includes user 4, user 5...

[0160] The present application detects page elements in a first document page through a triggering operation of a hidden control, and determines a target element to be hidden in the page element based on the detection result. The target element can be dynamically hidden in the document page based on the detection result, thereby preventing at least one of the basic user information or user behavior information included in the target element from being leaked, thereby improving the flexibility and security of document display.

[0161] This application hides the target elements by hiding the controls, so that the information of the user when viewing the document interface cannot be obtained by other users, thereby improving the security of the information when the user views the document, thereby improving the user experience and user stickiness.

[0162] In an exemplary embodiment of the present application, the second document page may further include an editing control, which may be used to change the document from a viewing state to an editing state. In the editing state, the user may modify the content of the document.

[0163] Exemplarily, when the first user has editing permission for the document, in response to the triggering operation of the editing control, a second prompt message is displayed in the second document page, the second prompt message is used to prompt the first user to determine the first user's status in the document, and the second prompt message includes a confirmation control and a cancel control; in response to the triggering operation of the confirmation control, the status of the document is modified to an editing status, and the target element of the first user is displayed in the second document page; or, in response to the triggering operation of the cancel control, the target element of the first user is hidden on the second document page or the hidden element corresponding to the target element of the first user is displayed.

[0164] In an exemplary embodiment of the present application, the creator of a document can set permissions for each user when creating the document. For example, the permissions of the user can include viewing permissions and editing permissions. When the first user has the editing permission of the document, the first user can edit the document through the editing control. When the triggering operation of the editing control is detected, the second prompt information is displayed in the second document page. The second prompt information can be used to remind the current user to determine the invisible state of the first user in the document.

[0165] Fig.14 is a schematic diagram of a second document page including second prompt information provided in the first embodiment of the present application. Fig.14 As shown, when the triggering operation of the editing control is detected, the second prompt information 1400 is displayed on the second document mask, and the second prompt information 1400 may include prompt content 1401, cancel control 1402 and confirmation control 1403. Among them, the prompt content 1401 may be "When editing content, the invisible state will temporarily disappear." If the cancel control 1402 is triggered, the current document state, that is, the viewing state, is retained, and the user can view the current document content in stealth; if the confirmation control 1403 is triggered, the state of the current document is changed to the editing state, and the target element of the current user (first user) is changed from the invisible state to the non-invisible state, that is, the target element of the first user can be viewed by the second user, and the second user is the user other than the current user who is viewing or editing the current document.

[0166] Fig.15 is a schematic diagram of a second document page including second prompt information provided in the second embodiment of the present application. Fig.15As shown, when the trigger operation of the edit control 1504 is detected, the second prompt information 1500 is displayed on the second document mask, and the second prompt information 1500 may include prompt content 1501, cancel control 1502 and confirm control 1503. Among them, the prompt content 1501, cancel control 1502 and confirm control 1503 are Fig.14 The functions of the prompt content 1401, the cancel control 1402 and the confirmation control 1403 are similar and are not described in detail here.

[0167] It should be noted that, after detecting the triggering operation of a certain control, the server can send a calling object to the terminal of the second user (other users who view or edit the current document), and the terminal of the second user detects the page elements in the current document page based on the calling object, and updates the current document page based on the detection results. The updating process of the document page is similar to steps 230 and 240, and will not be elaborated here.

[0168] In an exemplary embodiment of the present application, after displaying the second document page, the current user can also view the target elements of other users based on the second document page. The present application takes the second user viewing the target elements of the reference user based on the second document page as an example for explanation, and the process of the second user viewing the target elements of the reference user based on the second document page may include: receiving an information viewing request from the second user, the information viewing request is used to request to view the target elements of the reference user; when the reference user is in an invisible state, displaying a third prompt message on the second document page of the second user, the third prompt message is used to prompt the second user that he does not have the authority to view the information; or, when the reference user is not in an invisible state, displaying the target elements of the reference user on the second document page of the second user based on the information viewing request.

[0169] Exemplarily, the second user's terminal sends an information viewing request to the server. After receiving the second user's information viewing request, the server can determine the target element of the reference user based on the information viewing request, wherein the reference user is the user for whom the second user requests to view information, and the target element can be at least one of the user basic information or user behavior information of the reference user. The server can obtain the document viewing status of the reference user in the terminal of the reference user, and send the document viewing status of the reference user to the terminal of the second user.

[0170] If the reference user is in an invisible state when viewing the document, a third prompt message is displayed on the second document page of the second user, and the third prompt message is used to prompt the second user that he does not have the authority to view the information. For example, the third prompt message is "Sorry, this user is an invisible user and cannot view user information." If the reference user is in a non-invisible state when viewing the document, a target element of the reference user is displayed on the second document page of the second user based on the information viewing request, for example, an information panel of the reference user is displayed on the second document page of the second user, and the information panel of the reference user may include at least one of the reference user account, the reference user name, or the reference user avatar.

[0171] In an exemplary embodiment of the present application, when a configuration condition associated with a page element changes, an updated expression string is obtained based on the expression string and modification information corresponding to the changed configuration condition; an updated calling object is determined based on the updated expression string, and the modification information includes at least one of increasing the configuration condition associated with the page element, reducing the configuration condition associated with the page element, or modifying the configuration condition associated with the page element; the updated calling object is sent to the terminal of the user who views or edits the document.

[0172] Exemplarily, when the configuration condition associated with the page element changes, the server can obtain the modification information corresponding to the configuration condition, wherein the modification information may include but is not limited to adding a configuration condition, reducing a configuration condition, and modifying a configuration condition. The expression string is updated using the modification information corresponding to the configuration condition to obtain an updated expression string, and then the updated call object is determined using the updated expression string, and the updated call object is sent to the terminal of the user who views or edits the document.

[0173] Take the scenario where the current user experiences incognito viewing of documents as an example. For example, when the user experiences incognito viewing of documents, the duration of incognito is 15 minutes. At this time, the configuration conditions corresponding to the page elements need to be increased, that is, the incognito duration of the current user's target element is 15 minutes. The expression string is updated based on the configuration conditions of the incognito duration of the target element, and an updated call object is generated.

[0174] It should be noted that the process of determining the updated calling object using the updated expression string is similar to step 221 to step 224, and will not be described in detail here.

[0175] In an exemplary embodiment of the present application, after the server sends the updated call object to the terminal of the user viewing or editing the document, the terminal of the user viewing or editing the document updates the second document page (the current document page) based on the updated call object. The process of the user's terminal updating the second document page based on the updated call object may include: determining a second reference area in the second document page based on the updated call object, the second reference area being the area of ​​the call object where the update is performed; and displaying a third document page, the third document page being obtained by updating the page elements of the second reference area in the second document page.

[0176] Exemplarily, after the server sends the updated call object to the terminal of the user who views or edits the document, the user's terminal parses the updated expression string contained in the updated call object, determines the parameter value corresponding to the variable parameter in the second document page based on the variable parameter contained in the updated expression string, and determines the second reference area in the second document page using the determined variable. The user's terminal can update the page element based on the detection result of the page element in the second reference area to obtain a third document page.

[0177] When the configuration conditions associated with the page elements change, compared with the prior art of generating a new program version by modifying the code of the user terminal, the present application obtains an updated calling object based on the modification information of the configuration conditions, and the terminal of the user who views or edits the document updates the page elements in the second reference area of ​​the second document page based on the updated calling object to obtain a third document page. The present application can realize dynamic updating of page elements by updating the page elements based on the detection results of the calling object in the second reference area. Updating page elements by calling objects can simplify the update process of page elements, thereby improving the flexibility and scalability of document page updates. The update process is easy to upgrade and maintain, making document pages suitable for more application scenarios and meeting diverse user needs.

[0178] The present application also provides a device for displaying a document. Fig.16 is a schematic diagram of a document display device structure provided in an embodiment of the present application, such as Fig.16 As shown, the device comprises:

[0179] The display module 1510 is used to display a first document page, where the first document page includes multiple page elements, and the multiple page elements include hidden controls.

[0180] The detection module 1520 detects the configuration conditions associated with multiple page elements in the first document page in response to the triggering operation of the hidden control, and obtains the detection results. The configuration conditions associated with any page element include variable parameters and operations of the variable parameters. The variable parameters are dynamically changing parameters corresponding to any page element.
