Description

A data sorting method and device

technical field

The invention relates to the field of data processing, in particular to a data sorting method and device.

Background technique

With the rapid development of science and technology, computers are widely used in the fields of work and life due to their powerful functions. In daily work, it is often necessary to realize different functions through various application systems, such as scoring, saving, and publishing all manuscripts in the system through the newspaper assessment system.

When the user logs in to the application system to perform corresponding operations, such as viewing the data information in the operating system, it may be required to implement some additional functions in the above-mentioned application system that has been put into use, such as presenting the above-mentioned data in the operation interface of the application system The result of sorting the information according to the corresponding sorting rules. For example, for the existing newspaper evaluation system, users with higher priority can view the ranking of all current manuscripts in the presentation interface of the newspaper evaluation system during the process of grading manuscripts, that is, the above-mentioned priority is higher. Users can view the results of all manuscripts sorted from high to low after passing a round of review.

In view of the above-mentioned situation of adding new functions to the application system that has been put into use, the addition of the above-mentioned new functions of the application system is usually implemented by modifying the source code of the application system. When the business logic itself carried by the application system is relatively complex, it will be difficult to modify the source code of the application system, and it will take a certain amount of manpower to complete the realization of the new functions of the application system; and, the method of modifying the source code is adopted Adding new functions of the application system requires adding code corresponding to the above new functions in the source code, which is equivalent to adding a large number of source codes to realize new functions on the basis of the original source code, thereby further increasing the business carried by the application system. The complexity of the logic, the high-complexity application system needs to consume more resources of the server during operation, and brings greater computing pressure to the server, thus increasing the cost of system maintenance. In addition, the above-mentioned application system is a system that has been tested and put into use, and has a certain degree of stability. When the source code of the application system is modified to add other functions, there may be some subtle logic errors in the newly modified source code, resulting in There are certain application hidden dangers in the application system, that is, the application system has poor stability.

It can be seen that, in the prior art, when it is necessary to add a sorting function to an application system that has already been put into use, the source code of the application system needs to be modified, thereby consuming manpower, increasing system maintenance costs, and making the system poor in stability.

Detailed ways

In the embodiment of the present invention, by installing a JS (JavaScript, scripting language) plug-in in the client, the JS plug-in uses the AJAX (Asynchronous JavaScript And XML, asynchronous JavaScript and XML, or called dynamic loading) method to obtain Authority information, when it is determined that the user has the authority to view the sorting results, the AJAX method is used to obtain the corresponding data information and the preset sorting rules in the server, and the above data is sorted according to the preset sorting rules. By adopting the technical scheme of the present invention, it is not necessary to modify the source code in the server corresponding to the existing application system, and the data information in the existing application system can be realized conveniently and quickly only by installing the JS plug-in compiled for the application system on the client side. The sorting process of the data in the list does not need to consume a lot of human resources, effectively avoiding the problem of high system maintenance costs when adding new functions to the existing application system, and does not affect the stability of the original application system.

Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

Referring to Fig. 1, in the embodiment of the present invention, the detailed process for sorting the data in the server is:

Step 100: After receiving the login server instruction sent by the user, the client determines whether the JS plug-in is installed locally.

In the embodiment of the present invention, after the user interface in the application system corresponding to the server is loaded, it is judged whether the JS plug-in is locally installed on the client.

Step 110: When it is determined that the JS plug-in has been installed locally, the JS plug-in obtains the identification information of the above-mentioned server, and invokes the authority information of the user in the above-mentioned server according to the identification information.

When it is determined that the JS plug-in is not installed locally, the JS plug-in is installed locally on the client. When there is a user logging into the server, after the JS plug-in detects the current user, the AJAX method can be used to obtain the user's permission information.

Step 120: When the JS plug-in determines that the user has the right to view the sorted results according to the authority information of the user, the AJAX method is used to obtain the data information list and the sorting rules in the server.

In the embodiment of the present invention, after the JS plug-in obtains the user's authority information, it can determine whether to display the sorting function key in the data information presentation page of the application system according to the user's authority information. Wherein, the permission information of the above user includes the user's permission to view the sorting results, and the user does not have the permission to view the sorting results. At this time, if it is determined that the above-mentioned user has the right to view the sorting results, then display a sorting prompt message on the data information presentation page for the user to choose, for example, display a sorting function key on the data information presentation page, or pop up a sorting prompt dialog box, Ask the user whether to sort the data in the data information presentation interface; when the user clicks the sort function button, or clicks the confirmation button in the above sort prompt dialog box, that is, the JS plug-in in the application system receives the user's instruction to confirm and proceed When sorting, use the AJAX method to obtain the data information list and sorting rules stored in the server.

Preferably, the above sorting rules include sorting by score, sorting by last review time, etc. According to the above sorting rules, correspondingly, when it is determined that the user has the right to view the sorting results, multiple sorting function keys are displayed on the data information presentation page for the user to choose, or multiple sorting functions are displayed in the pop-up sorting prompt dialog box The selection key is for the user to select.

Step 130: The JS plug-in sorts the data in the above data information list according to the above sorting rules, and presents the sorting results.

In the embodiment of the present invention, the JS plug-in sorts the data in the above data information list according to the acquired sorting rules in the server.

Further, after finishing sorting the data in the above data information list, refresh all the information in the data information presentation page; or refresh some information that has changed in the data information presentation page; and update the refreshed data information presentation page presented. When the latter method is used to display the sorted data information presentation page, the time for sorting the data can be reduced, and the data sorting result can be obtained more quickly.

In particular, when the JS plug-in detects that the list of data information in the server changes (for example, adding or deleting a piece of data information, and modifying one or more pieces of data information), it can display data updates on the data information presentation page Prompt information, for example, in the form of a pop-up dialog box on the page to prompt the user that the data information list has been updated, and ask the user whether to reorder the updated data information list; when the JS plug-in receives the user's instruction to confirm and display the updated data information is presented After the page is displayed, the result of sorting the updated data list is displayed, and the updated data information list and sorting rules are obtained by using the AJAX method, and the data in the above updated data information list are sorted according to the sorting rules; Then, the updated sorting result is presented on the above data information presentation page.

Referring to Fig. 2, it is a logical schematic diagram of sorting data in the server in an embodiment of the present invention, wherein the operating system corresponding to the server can be divided into two parts, that is, the presentation layer (that is, for displaying the above-mentioned data information, that is, the above-mentioned data information presentation page), and the control layer (that is, used to save the data information list and sorting rules). Referring to the above logical schematic diagram, in the embodiment of the present invention, a JS plug-in is installed in the application system, the JS plug-in sends information to the control layer, and obtains a list of data information and sorting rules saved by the control layer, and the JS plug-in performs the above-mentioned sorting rules according to the sorting rules. The list of data information is sorted.

It can be seen that, by adopting the technical scheme of the present invention, it is not necessary to notify the server to sort the data in the data information list according to the sorting rules stored locally every time in the process of sorting the data in the application system, and only need to call the JS plug-in The sorting sequence and data information list in the server can complete the data sorting process, thereby avoiding the problem of heavy system load caused by the server in the process of sorting data.

The following describes the sorting process of data in the application system in detail in combination with specific application scenarios.

Referring to Figure 3, the detailed process of sorting data in the server is as follows:

Step 300: When there is a logged-in user and it is determined that the JS plug-in is not installed locally, install the JS plug-in locally on the client.

Step 310: When the JS plug-in detects that there is a logged-in user, obtain the identification information of the currently logged-in user and the identification information of the server.

Step 320: The JS plug-in logs in to the server according to the identification information of the above-mentioned server, and uses the AJAX method to call the permission information corresponding to the identification information of the current login user from the server according to the above-mentioned identification information of the currently logged-in user. According to the permission information, It is judged whether the currently logged-in user has the right to view the sorted results, and if the currently logged-in user does not have the right to view the sorted results, perform step 330 ; otherwise, perform step 340 .

Step 330: Do not display the sorting function key on the data information presentation page.

Step 340: Display the sorting function keys on the above data information presentation page.

Step 350: When the JS plug-in detects that the user clicks the sorting function key and instructs to confirm the sorting, use the AJAX method to obtain the list of data information stored in the server and the sorting rules, and sort the items in the above data information list according to the sorting rules obtained above. The data is sorted.

Step 360: Refresh the changed part of the above data information presentation page, and present the refreshed data information presentation page.

Based on the above technical solution, as shown in FIG. 4, a device for sorting data in the application system can be constructed, including an installation unit 40, a first acquisition unit 41, a second acquisition unit 42, and a sorting unit 43, wherein:

The installation unit 40 is configured to determine whether the Java scripting language JS plug-in is installed locally after receiving the login server instruction sent by the user;

The first obtaining unit 41 is configured to, when it is determined that the JS plug-in has been installed locally, the JS plug-in obtains the identification information of the server, and invokes the authority information of the user in the server according to the identification information;

The second acquiring unit 42 is configured to use the AJAX method to acquire the data information list and sorting rules in the server when determining that the user has the authority to view the sorting results according to the authority information of the user;

The sorting unit 43 is configured to sort the data in the above-mentioned data information list according to the above-mentioned sorting rule, and present the sorting result.

To sum up, in the embodiment of the present invention, after the client receives the login server instruction sent by the user, it judges whether the JS plug-in is installed locally. The authority information of the current user, when it is determined that the current user has the authority to view the sorting results, use the AJAX method to obtain the data information list and sorting rules; sort the data in the above data information list according to the sorting rules. By adopting the technical solution of the present invention, there is no need to modify the source code in the application system, and the sorting process of the data in the existing application system can be realized only by installing the JS plug-in in the application system and using the AJAX method, and the operation process is convenient and fast.
