[0051] 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.

[0052] Figure 1 is a cascade information echo method according to an embodiment of the present invention, such as Figure 1 As shown, the cascade information echoing method may include the following steps:

[0053] Step S101: receiving a request for echoing cascade information, wherein the request for echoing includes: a characteristic identifier of the cascade information and a current level to be echoed in the cascade information;

[0054] Step S102: according to the characteristic identifier of the cascade information, calling the preset information query interface, obtaining and assembling the information of each level before the current level to be echoed and the information of the current level to be echoed;

[0055] Step S103: injecting information of each level before the current level to be echoed and information of the current level to be echoed into a pre-selected cascade component;

[0056] Step S104: echoing the information of each level before the current level to be echoed and the information of the current level to be echoed through the cascade component.

[0057] The characteristic identifier of the cascade information may be characteristic information of a data table storing the cascade information, such as the name of the data table, characteristic code, etc. The characteristic identifier of the cascade information may also be characteristic identifier of a data block, such as a data block number, a data block name, etc.

[0058] In addition, the feature identifier of the cascade information may also be the feature identifier of the first level in the cascade information.

[0059] The cascade information may be stored in a server or a terminal. Accordingly, step S102 calls a preset information query interface to obtain information of each level before the current level to be echoed in the cascade information and information of the current level to be echoed from the server or the terminal.

[0060] The current level to be echoed refers to the level to which the information to be echoed belongs. For example, a cascaded information is: Province A (first level) → City B (second level) → District C (third level). If the information to be echoed is District C, the current level to be echoed is the third level.

[0061] The selected cascade component may be any existing cascade component, for example, the Cascader cascade selection component in the Ant Design component library.

[0062] exist Figure 1 In the illustrated embodiment, during the cascade information echoing process, the information query interface can be called to obtain and assemble the information of each level before the current level to be echoed and the information of the current level to be echoed included in the echo request according to the characteristic identifier of the cascade information included in the echo request. Therefore, even if the information of any level is modified or edited, the information of each level before the current level to be echoed and the information of the current level to be echoed can be obtained according to the characteristic identifier of the cascade information included in the echo request, and the modified or edited information can be obtained. Then, by injecting this information into the cascade component and echoing this information through the cascade component, the dynamic echoing of the cascade information is realized.

[0063] In an embodiment of the present invention, a specific implementation method of obtaining and assembling information of each level before the current level to be echoed and information of the current level to be echoed may include: obtaining and assembling information of each level from the first level of cascade information to the current level to be echoed in a recursive manner.

[0064] Among them, the recursive method is adopted to obtain and assemble the information of each level through the recursive search module. The part of the running program of the recursive search module can be as follows: Figure 2 shown.

[0065] from Figure 2 As can be seen in the figure, by calling the information query interface, the recursive search module obtains the information of the current level based on: the parent level ID corresponding to the current level (the parent level ID is the ID of the level above the current level), and the relevant index and data under the index can be obtained according to the parent level ID; by traversing the loop, the data of the corresponding level is found and assembled into children. After reaching the last level, the loop stops querying.

[0066] That is, if the current level to be echoed is not less than two levels, such as Figure 3 As shown, obtaining and assembling information at each level in a recursive manner may include the following steps:

[0067] Step S301: acquiring the information of the first level and the feature identifier of the first level according to the feature identifier of the cascade information, and assembling the information of the first level;

[0068] Step S302: Based on the feature identifier of the first level, sequentially obtain and assemble information of each level from the second level to the current level to be echoed.

[0069] Among them, the Figure 3 The steps shown can be Figure 2 The recursive search module implementation shown.

[0070] That is, the above recursive method is to obtain and assemble information from the first level to the subsequent levels in a progressive manner. For example, for the cascade information A Province (first level) → B City (second level) → C District (third level) → D Tourist Attractions (fourth level), the current level to be echoed is the fourth level, then first obtain the first-level information "A Province", and assemble the "A Province", for example, the "A Province" can be assembled into the recursive search module, and then based on the first-level feature identifier, sequentially obtain the second-level information "B City", the third-level information "C District" and the fourth-level information "D Tourist Attractions", and assemble "B City", "C District" and "D Tourist Attractions", for example, assemble "B City", "C District" and "D Tourist Attractions" into the recursive search module.

[0071] Among them, Figure 4 As shown, sequentially acquiring and assembling information of each level from the second level to the current level to be echoed may include the following steps:

[0072] Step S401: when each level from the second level to the current level to be echoed in the cascade information is taken as the current level, the following steps are performed: obtaining information of the current level according to the feature identifier of the previous level of the current level, and assembling the information of the current level;

[0073] Step S402: determine whether the current level is the last level, if yes, end the current process; otherwise, execute step S403;

[0074] Step S403: Obtain the feature identifier of the current level.

[0075] For example, for the cascade information A Province (first level) → B City (second level) → C District (third level) → D Tourist Attraction (fourth level), the current level to be echoed is the fourth level. After obtaining the information "A Province" of the first level and assembling the "A Province", for example, "A Province" can be assembled into the recursive search module, and then based on the feature identifier of the first level, the information "B City" of the second level is obtained, and "B City" is assembled, for example, "B City" is assembled into the recursive search module; since the second level is not the last level, obtaining the second level The feature identifier of the second level is used to obtain the information "Area C" of the third level, and assemble "Area C", such as assembling "Area C" into a recursive search module; since the third level is not the last level, the feature identifier of the third level is obtained, and based on the feature identifier of the third level, the information "D Tourist Attractions" of the fourth level is obtained, and assemble "D Tourist Attractions", such as assembling "D Tourist Attractions" into a recursive search module; since the fourth level is already the last level, there is no need to obtain the feature identifier of the fourth level.

[0076] Generally speaking, when cascading information is stored, it is usually stored in an associated manner. For example, the information storage of each level is stored based on the feature identifier of the previous level. Therefore, the current level can be found through the feature identifier of the previous level. By searching and obtaining the next level through the previous level, the information of the next level can be accurately found. Even if the information of the next level is changed, the updated information can be obtained in time, thereby ensuring the accuracy of the information obtained, so that the information can be displayed completely and accurately.

[0077] In the embodiment of the present invention, the specific implementation of assembling the information of each level may include: filling the information of each level into a preset tree structure option according to the hierarchical relationship between the first level to the current level to be echoed in the cascade information.

[0078] The tree structure options can be Figure 5 as well as Figure 6 For example, for cascade information: A1 province (first level) → B1 city (second level) → C1 district (third level) and A2 province (first level) → B2 city (second level) → C2 district (third level) are filled in respectively. Figure 5 as well as Figure 6 In the tree structure options shown.

[0079] In the embodiment of the present invention, a specific implementation of injecting information of each level before the current level to be echoed and information of the current level to be echoed into a pre-selected cascade component may include: injecting information filled in the tree structure options into the pre-selected cascade component.

[0080] In the embodiment of the present invention, Figure 7As shown, after receiving the echo request for cascade information, the following steps may be further included:

[0081] Step S701: Determine whether the current level to be echoed is the first level. If yes, execute step S702; otherwise, execute step S703;

[0082] Step S702: calling the information query interface, obtaining the information of the first level according to the feature identifier of the first level, injecting the information of the first level into the pre-selected cascade component, echoing the information of the first level through the cascade component, and ending the current process;

[0083] Step S703: Execute the step of acquiring and assembling the information of each level before the current level to be echoed and the information of the current level to be echoed.

[0084] The following takes the cascade information (Province A (first level) → City B (second level) → District C (third level) → Tourist Attraction D (fourth level)) as an example to explain the cascade information echo process in detail. Figure 8 As shown, the cascade information echoing method may include the following steps:

[0085] Step S801: receiving an echo request of cascade information, wherein the echo request includes: a feature identifier of the first level and a current level to be echoed in the cascade information;

[0086] For example, for cascade information (Province A (first level) → City B (second level) → District C (third level) → Tourist Attraction D (fourth level)), the echo request includes: the feature identifier of the first level and the current level to be echoed: the fourth level.

[0087] Step S802: Determine whether the current level to be echoed is the first level. If yes, execute step S803; otherwise, execute step S805;

[0088] For example, if the current level to be echoed is the fourth level, not the first level, then step S805 is executed.

[0089] Step S803: directly calling the information query interface to obtain the first-level information according to the first-level feature identifier;

[0090] Step S804: injecting the information of the first level into the pre-selected cascade component, echoing the information of the first level through the cascade component, and ending the current process;

[0091] The above steps S803 and S804 are mainly for information that does not have a hierarchical relationship. After the information is directly obtained, it is injected into the cascade component to realize the echo.

[0092] For each level from the second level to the current level to be echoed in the cascade information as the current level, execute:

[0093] Step S805: acquiring information of the current level according to the feature identifier of the level above the current level, and assembling the information of the current level;

[0094] For cascading information (Province A (first level) → City B (second level) → District C (third level) → Tourist Attraction D (fourth level)), for example, if the current level is the second level, then according to the feature identifier of the first level, the preset information query interface is called to obtain City B from the stored information; for another example, if the current level is the third level, then according to the feature identifier of the second level, the preset information query interface is called to obtain District C from the stored information, and so on.

[0095] Among them, assembling the information of the current level can assemble the information of the current level into Figure 5 or Figure 6 In the structure shown.

[0096] Step S806: Determine whether the current level is the last level, if yes, execute step S808; otherwise, execute step S807;

[0097] Step S807: Obtain the feature identifier of the current level, and take the current level as the previous level, and execute step S805;

[0098] Step S808: injecting information of each level before the current level to be echoed and information of the current level to be echoed into the pre-selected cascade component;

[0099] Step S809: echoing the information of each level before the current level to be echoed and the information of the current level to be echoed through the cascade component.
