[0081] Figure 7 It is a schematic diagram of the structure of a computer system of a terminal device or a server suitable for implementing an embodiment of the present invention. DETAILED DESCRIPTION

[0082] The following is a description of exemplary embodiments of the present invention in conjunction with the accompanying drawings, including various details of the embodiments of the present invention to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0083] In the prior art, when the client monitors the page scrolling, it determines the element currently displayed in the scrolling window based on the attribute information of the element, and determines whether the element needs to be exposed through the embedding solution. If so, it determines that the element is an exposure element and sends the exposure element to the server.

[0084] However, in this method, the client frequently sends requests to the server, increasing the pressure on the server. In addition, page jumps or re-rendering may cause the client to fail to send requests and lose exposure data. In addition, due to the high computing pressure on the client, elements such as animations on the page cannot be displayed normally, causing the page to freeze.

[0085] like Figure 1 As shown, an embodiment of the present invention provides a method for determining an exposure element, which is applied to a client, and the method includes:

[0086] Step 101: Determine the size of the scroll window.

[0087] The client can be a PC or mobile application, such as a browser, email, etc.

[0088] The scrolling window is used to display the content of the page. As the page scrolls, elements at different positions in the page can be displayed in the scrolling window. The size of the scrolling window may include: the height and width of the scrolling window. The size of the scrolling window obtained by the client may be different depending on the device where the client is located. For example, under normal circumstances, the height of the scrolling window on the PC side of the same browser is greater than the height of the scrolling window on the mobile side. The size of the scrolling window obtained by the client may also be different depending on the type of client. For example, the width of the scrolling window of the web version of mailbox A may be greater than the width of the scrolling window of the web version of mailbox B.

[0089] In the embodiment of the present invention, the size of the scrolling window can be obtained after the page is loaded.

[0090] In actual application scenarios, the execution order of determining the size of the scroll window, obtaining the attribute information of the element, and recording the scrolling track information can be adjusted, and the embodiment of the present invention does not limit it. For example, step 101 and step 102 are executed interchangeably, step 101 is executed after step 104, etc.

[0091] Step 102: Obtain attribute information of several elements on the page.

[0092] The attribute information of an element includes: the element's height, width, position on the page and other layout information.

[0093] Step 103: monitor whether the page is scrolling, if it is monitored that the page is scrolling, execute step 104.

[0094] In actual application scenarios, whether the page is scrolled can be determined based on whether the scroll bar on the page moves or whether the position of the element on the page in the scroll window changes. The scrolling direction can be up and down or left and right.

[0095] Step 104: Record the scrolling track information.

[0096] The scrolling track information is used to record the scrolling track of the page. From monitoring the page scrolling to sending the scroll window size to the server, the page may scroll only once continuously or multiple times intermittently.

[0097] The scrolling track information may include: the scrolling start position, the scrolling stop position, and the scrolling direction change position.

[0098] In an application scenario, the page first scrolls downward 1 and then scrolls upward 2. The scrolling track information includes: the scrolling start position is 0, the scrolling direction change position is 1, and the scrolling end position is -1.

[0099] The scrolling direction and distance may also be recorded in the scrolling track information. The page first scrolls downward 1 and then scrolls upward 2. The scrolling track information includes: scrolling downward 1 and scrolling upward 2.

[0100] Step 105: Send the size of the scroll window, attribute information of several elements and scroll track information to the server.

[0101] The server determines the exposure element according to the size of the scrolling window, the attribute information of several elements and the scrolling track information.

[0102] The client determines the size of the scroll window, the attribute information of the element, and the scrolling track information, and provides them to the server, which determines the exposure element based on this information. Since the server undertakes part of the calculation process, the client's calculation amount is reduced, reducing the probability of client lag.

[0103] A page may include multiple elements. In actual application scenarios, it may not be necessary to pay attention to whether each element in the page is exposed. In view of this situation, in one embodiment of the present invention, the multiple elements include: multiple buried point elements and multiple other elements.

[0104] The method further includes:

[0105] According to the tracking point plan of the page, determine several tracking point elements from several elements;

[0106] Determine the identification of several tracking elements;

[0107] Send the scroll window size, attribute information of several elements, and scroll track information to the server, including:

[0108] The size of the scroll window, scroll track information, attribute information and identifiers of several embedding elements, and attribute information of several other elements are sent to the server.

[0109] The embodiment of the present invention can determine whether an element is a buried point element through an identifier, and the server can determine whether the element is an exposed element based on the identifier. The client or server can distinguish buried point elements from other elements through the identifier, and the server can also store the identifier of the exposed element in a database or other location. By querying the identifier in the database, the exposed buried point element can be determined.

[0110] In one embodiment of the present invention, the method may include: adding identifiers of several buried elements to real DOM nodes corresponding to the several buried elements respectively; wherein the real DOM nodes corresponding to the several elements constitute a real DOM tree;

[0111] Get the attribute information of several elements on the page, including:

[0112] Asynchronously traverse the real DOM tree to obtain a virtual DOM tree; wherein the virtual DOM tree includes: attribute information and identifiers of several embedding elements and attribute information of several other elements;

[0113] Send the scroll window size, scroll track information, attribute information and identifiers of several embedding elements, and attribute information of several other elements to the server, including:

[0114] Send the scroll window size, scroll track information, and virtual DOM tree to the server.

[0115] In addition to storing the attribute information of DOM nodes in the real DOM tree, the virtual DOM tree can also store the hierarchical relationship between DOM nodes.

[0116] The format of the virtual DOM tree is as follows:

[0117]

[0118] The attribute information and identifier of the tracking point element and the attribute information of other elements are stored in the form of key-value pairs.

[0119] The embodiment of the present invention stores the attribute information and identification of the buried element and the attribute information of other elements through the virtual DOM tree and provides it to the server, so that the server can more quickly determine the exposed elements by traversing the virtual DOM tree. Considering that frequently sending the attribute information of the element to the server will increase the pressure on the server, in the actual application scenario, when the trigger condition is met, the size of the scrolling window, the attribute information of several elements and the scrolling track information are sent to the server.

[0120] The trigger condition may be page destruction or page re-rendering. Specifically, in one embodiment of the present invention, the method further includes:

[0121] Monitor whether the page is destroyed or re-rendered. If so, send the size of the scroll window, attribute information of several elements, and scroll track information to the server.

[0122] Taking page destruction as an example, from the time the page is scrolled to the time the page is destroyed, if the page scrolls multiple times intermittently, the client does not need to send information to the server every time it scrolls, but instead sends the obtained information to the server after the page is destroyed.

[0123] Among them, page destruction includes: page closing, page rollback, etc.

[0124] The trigger condition may also be that the size of the scroll window, the attribute information of the element, and the data volume of the scroll track information reach a specified threshold. In addition, the size of the scroll window, the attribute information of several elements, and the scroll track information may also be sent to the server according to a preset time period.

[0125] like Figure 2 As shown, an embodiment of the present invention provides a method for determining an exposure element, which is applied to a server and includes:

[0126] Step 201: receiving the size of the scroll window, attribute information of several elements on the page, and scroll track information sent by the client.

[0127] Step 202: Determine the exposure element according to the size of the scrolling window, attribute information of several elements and scrolling track information.

[0128] In the embodiment of the present invention, the exposure element is determined by the server, which reduces the amount of calculation on the client and reduces the probability of freeze on the client.

[0129] In one embodiment of the present invention, receiving the size of the scroll window, the attribute information of several elements on the page, and the scroll track information sent by the client includes:

[0130] Receive the size of the scrolling window, scrolling track information, attribute information and identifiers of several embedding elements, and attribute information of several other elements sent by the client; wherein the several elements include: several embedding elements and several other elements;

[0131] According to the size of the scrolling window, the attribute information of several elements and the scrolling track information, the exposure elements are determined, including:

[0132] The exposure element is determined based on the size of the scrolling window, the scrolling track information, the attribute information and identification of several embedded point elements, and the attribute information of several other elements.

[0133] In actual application scenarios, it is possible to determine whether each element in the page is exposed. However, considering that this will increase the amount of computation on the client and server, the embodiment of the present invention only determines whether the buried element is exposed, which can reduce the amount of computation on the client and server.

[0134] In one embodiment of the present invention, receiving the size of the scrolling window, scrolling track information, attribute information and identifiers of several embedding elements, and attribute information of several other elements sent by the client includes:

[0135] Receive the size of the scroll window, scroll track information and virtual DOM tree sent by the client; wherein the virtual DOM tree includes: attribute information and identifiers of several embedding elements and attribute information of several other elements;

[0136] The exposure elements are determined based on the size of the scrolling window, scrolling track information, attribute information and identifiers of several embedding elements, and attribute information of several other elements, including:

[0137] Determine the exposed elements based on the size of the scroll window, scroll track information, and virtual DOM tree.

[0138] The embodiment of the present invention stores the attribute information and identification of the embedded element and the attribute information of other elements through the virtual DOM tree. Since the virtual DOM tree stores data in the form of objects, the server can determine the exposed elements more quickly.

[0139] In the embodiment of the present invention, determining the exposure element according to the size of the scrolling window, the scrolling track information and the virtual DOM tree includes:

[0140] Determine the view area according to the size of the scroll window and the scroll track information;

[0141] Determine the exposed elements based on the view area and the virtual DOM tree.

[0142] In the embodiment of the present invention, the server determines the area of ​​the page exposure, i.e., the view area, according to the size of the scrolling window and the scrolling track information. Compared with determining the buried element according to the virtual DOM tree and determining the exposed element according to the buried element, the size of the scrolling window and the scrolling track information, the embodiment of the present invention can reduce the amount of calculation of the server and determine the exposed element more quickly.

[0143] In one embodiment of the present invention, the scrolling track information includes: a scrolling start position, a scrolling stop position, and a scrolling direction change position;

[0144] Determine the view area based on the size of the scroll window and the scroll track information, including:

[0145] Determine the scrolling distance according to the scrolling start position, the scrolling stop position and the scrolling direction change position;

[0146] Determine the view area based on the scroll distance and the size of the scroll window.

[0147] The scrolling track information includes: the scrolling start position is 0, the scrolling direction change position is 1, the scrolling direction change position is -1, and the scrolling end position is 2. It can be concluded that the page scrolls down 1, scrolls up 2, and scrolls down 3. Scrolling distance = 1 + (2-1) + (3-2) = 3.

[0148] Scroll distance + scroll window width = view area width, scroll window length = view area length.

[0149] In one embodiment of the present invention, determining the exposed element according to the view area and the virtual DOM tree includes:

[0150] For each element of the virtual DOM tree:

[0151] It is determined whether the element is located in the viewing area according to the attribute information of the element, and if so, it is determined whether the element has an identification, and if so, it is determined that the element is an exposure element.

[0152] Specifically, the server traverses each node of the virtual DOM and determines whether the element is in the view area based on the height, width and position of the element in the page. If it is in the view area, it means that the element is exposed. However, in the embodiment of the present invention, only the exposed buried elements are concerned, and the buried elements can be confirmed by identification. The exposed buried elements are exposed elements.

[0153] like Figure 3 As shown, an embodiment of the present invention provides a method for determining an exposure element, which is applied to a system for determining an exposure element. The method includes:

[0154] Step 301: The client determines a number of embedding elements from a number of elements according to the embedding scheme of the page.

[0155] Step 302: The client determines the identifiers of several tracking elements.

[0156] Step 303: The client adds the identifiers of the plurality of embedded elements to the real DOM nodes corresponding to the plurality of embedded elements, respectively, wherein the real DOM nodes corresponding to the plurality of elements constitute a real DOM tree.

[0157] Step 304: The client determines the size of the scroll window.

[0158] Step 305: The client asynchronously traverses the real DOM tree to obtain the virtual DOM tree.

[0159] The virtual DOM tree includes: attribute information and identifiers of several embedding elements and attribute information of several other elements.

[0160] Step 306: The client monitors whether the page is scrolled.

[0161] Step 307: When the client detects that the page is scrolling, it records the scrolling track information; the scrolling track information includes: the scrolling start position, the scrolling stop position and the scrolling direction change position.

[0162] Step 308: The client monitors whether the page is destroyed or re-rendered.

[0163] Step 309: When the client monitors whether the page is destroyed or re-rendered, it sends the size of the scroll window, scroll track information and virtual DOM tree to the server.

[0164] Step 310: The server determines the scrolling distance according to the scrolling start position, the scrolling stop position and the scrolling direction change position.

[0165] Step 311: The server determines the view area according to the scrolling distance and the size of the scrolling window.

[0166] Step 312: The server determines for each element of the virtual DOM tree whether the element is located in the viewing area according to the attribute information of the element. If so, execute step 313; otherwise, terminate the current process.

[0167] Step 313: The server determines whether the element has an identifier. If so, step 314 is executed. Otherwise, the current process is terminated.

[0168] Step 314: The server determines that the element is an exposed element.

[0169] In this system, the server determines the exposure elements based on the size of the scroll window and other data, which can reduce the amount of calculation on the client side and reduce the chance of client freezing. The client sends data to the server uniformly when the page is re-rendered or destroyed, reducing the number of times data is sent to the server and reducing resource consumption on both the client and server sides.
