Background
A Single Page Application (SPA) refers to a Single Page webApplication, i.e., an application with only one web Page, which is a web application that loads a Single html (HyperText Markup Language) Page and dynamically updates the Page when a user interacts with the application. Wherein, the single page jump only refreshes local resources, and common resources (such as js, css and the like) in the single page application only need to be loaded once.
Currently, when a single-page application calls a map application (such as a high-resolution map or a Baidu map) to render a plurality of maps in a page, a call interface of the map application is downloaded (i.e., loaded) for each rendering task, and the map application is called through the downloaded call interfaces to process the corresponding rendering tasks. Therefore, when a calling interface is downloaded in a current rendering task, a downloading request of the calling interface of another rendering task is easily interrupted, so that partial map rendering fails, for example, when a user applies for a car insurance claim in a single-page application and a plurality of maps such as the position of a surveyor and the navigation track of a trailer are rendered by calling related software, only the position of the surveyor can be rendered, but the navigation track of the trailer cannot be rendered. Therefore, how to solve the problem that when the existing single-page application calls the map application to render a plurality of maps, partial map rendering failure exists, so that the map rendering effect of the single-page application is poor becomes a technical problem to be solved urgently at present.

In fig. 1, the network communication module is mainly used for connecting to a server and performing data communication with the server; and the processor 1001 may call a map rendering program of the single-page application stored in the memory 1005 and perform the map rendering method of the single-page application provided by the embodiment of the present invention.
The embodiment of the invention provides a map rendering method for single-page application.
Referring to fig. 2, fig. 2 is a flowchart illustrating a map rendering method for a single-page application according to a first embodiment of the present invention.
In this embodiment, the map rendering method for single-page application is applied to a processor or a program for monitoring map calling of each page application, and the map rendering method for single-page application includes the following steps:
step S10, when receiving a map calling instruction sent by a single page application, determining whether a calling interface corresponding to the map application exists in a storage area corresponding to the single page application;
when a plurality of maps are rendered by the current single-page application, the calling interface of the map application is downloaded (loaded) for each rendering task, and when the downloading of the downloaded calling interface is successful, the map application is called by the downloaded calling interface to process the rendering task. However, when the previous rendering task downloads the call interface, the previous rendering task is easily interrupted by the request of downloading the call interface by the next rendering task, so that the previous rendering task cannot monitor the success of downloading the call interface, and the rendering of the previous rendering task fails, thereby causing the rendering failure of the map corresponding to the rendering task.
According to the method and the device, the mode that one calling interface is downloaded to process a plurality of rendering tasks is used for replacing the mode that the existing calling interfaces process a plurality of rendering tasks, and the problem that the single-page application map rendering effect is poor due to the fact that the downloading request of the calling interface of one rendering task is interrupted is solved.
In this embodiment, when a map call instruction of a map application sent by a single-page application is detected, it is first detected whether a downloaded call interface of the map application exists in a storage area (for example, a file storing data corresponding to the target page application) corresponding to the single-page application, and if the downloaded call interface exists, the downloaded call interface is directly called to sequentially process a plurality of rendering tasks without repeatedly downloading the call interface.
For example, the determining whether a call interface corresponding to the map application exists in the storage area corresponding to the single-page application specifically includes:
and determining whether an interface identifier of the calling interface or a variable identifier of a global variable for storing the calling interface exists in the storage area.
In this embodiment, when the downloading of the calling interface is completed, a global variable AMap is defined in the storage area of the single-page application, and is used for storing the calling interface of the map application. Therefore, when determining whether the downloaded call interface exists in the storage area, the interface identifier of the call interface may be searched in the storage area, and the variable identifier of the global variable may also be searched in the storage area, and if the interface identifier of the call interface exists in the storage area or the variable identifier of the global variable for storing the call interface exists in the storage area, it may indicate that the downloaded call interface exists in the storage area. If the interface identifier of the calling interface does not exist in the storage area, the variable identifier of the global variable for storing the calling interface does not exist, that is, the downloaded calling interface does not exist in the storage area.
Step S20, if the calling interface does not exist in the storage area, determining whether a first download task corresponding to the single-page application exists in a preset download task list based on a download task identifier;
in this embodiment, before downloading the map call interface, a script element needs to be newly created for each download task, and a corresponding Identifier (ID) is set for the script element corresponding to each download task. Through the method, the corresponding downloading task identifier (script element ID) is set for the downloading task corresponding to each page application, and the downloading data of the page application is recorded through the downloading task table. The map calling interface is used for receiving a map application, wherein the map calling interface is used for calling a map according to a map application, and the map calling interface is used for calling a map according to a map application; the download task table may also be a record table of download tasks corresponding to each page application, that is, record each call interface downloaded by each page application and a download task identifier corresponding to each download task of each call interface downloaded by each page application.
Specifically, if the downloaded call interface does not exist in the storage area, the identifier of the download task for downloading the call interface based on the single-page application is further searched in the download task list, and if the identifier exists in the download task list, the identifier indicates that the interface download task (the first download task) currently exists in the download.
Step S30, if the first download task exists in the download task list, wait for the execution of the first download task, and call the downloaded call interface to process the rendering tasks in the single-page application until the first download task is completed.
In this embodiment, when the first download task exists in the download task list, the download request of the invocation interface does not need to be repeatedly triggered, execution of the first download task in the download is waited, and when the first download task completes the download of the invocation interface, the invocation interface is invoked to sequentially process the rendering tasks. Therefore, when the single-page application does not have a calling interface for completing downloading, whether an interface downloading task in downloading exists in the single-page application is further judged, and if yes, the execution of the downloading task in downloading is waited until the execution is completed.
Further, the step S30 specifically includes:
if the first downloading task exists in the downloading task list, acquiring downloading time corresponding to the first downloading task;
and when the downloading time does not exceed a preset time threshold, generating and displaying prompt information in the downloading of a map calling interface, waiting for the execution of the first downloading task, and calling the downloaded calling interface to process a plurality of rendering tasks in the single-page application until the first downloading task is completed.
In this embodiment, if the first download task exists in the download task list, it indicates that the single-page application has sent a download request corresponding to downloading the call interface. That is to say, there are currently ongoing and incomplete download tasks, and in order to avoid the call interface download abnormality caused by the timeout of the download task, the download time of the download task is monitored, and if the download time does not exceed the preset time threshold, it indicates that the first download task is not abnormal, and a prompt message in the map call interface download is generated and displayed, so as to avoid the user from repeatedly triggering the download instruction, improve the user experience, and facilitate the user to know the map rendering progress.
Further, if the first download task exists in the download task list, after obtaining the download time corresponding to the first download task, the method further includes:
when the downloading time exceeds a preset time threshold, interrupting the first downloading task, sending a downloading request through a preset map downloading public component, generating a third downloading task of the calling interface downloaded by the single-page application, and adding a corresponding downloading task identifier to the third downloading task;
and waiting for the execution of the third downloading task until the third downloading task finishes downloading, and calling the downloaded calling interface to process the plurality of rendering tasks in the single-page application.
In this embodiment, when the download time exceeds a preset time threshold, that is, it indicates that the first download task is abnormal, the abnormal download task (the first download task) is interrupted, then a preset map download common component (a component for downloading a call interface of a map application) is called to resend a request for downloading the call interface to a server, that is, a new download task (a third download task) is created, and a corresponding identifier is added to the third download task, so that the third download task is searched based on the download task identifier of the third download task.
Specifically, in order to increase maintainability of the map rendering program, based on the existing logic code (such as the map rendering application program) for calling the map application to perform rendering task processing, the logic code for calling the interface download is extracted, and packaged as a map download common component for sending a download request to perform the calling interface download, so as to serve as a preset map download common component.
For example, the step of processing the plurality of rendering tasks in the single-page application by invoking the downloaded invocation interface specifically includes:
obtaining each map rendering task, and adding each map rendering task to a rendering task queue;
acquiring a rendering task in the rendering task queue as a target rendering task, calling the calling interface, and processing the target rendering task based on rendering data corresponding to the target rendering task;
acquiring a next rendering task in the rendering task queue as the target rendering task, and executing: and calling the calling interface, and processing the target rendering task based on rendering data corresponding to the target rendering task until all rendering tasks in the rendering task queue are completed.
In this embodiment, a plurality of map rendering tasks are added to the rendering task queue, and when it is monitored that the downloading of the calling interface is completed or the downloaded calling interface is detected to exist at present, each rendering task in the rendering task queue is sequentially processed through the calling interface. A global variable array initAmpaArray is predefined and used as the rendering task queue for storing a plurality of rendering tasks.
Specifically, a rendering task in the rendering task queue is obtained as a target rendering task, the call interface is called, and a map of a corresponding area in the single-page application is rendered according to rendering data corresponding to the target rendering task, so that processing of the target rendering task is completed. And then acquiring the next rendering task in the rendering task queue as an updated target rendering task, and calling the calling interface to sequentially complete the processing of each rendering task in the rendering task queue.
In a specific embodiment, when a rendering task is processed, a corresponding rendering completion identifier is added to the completed rendering task, so that the processed rendering task and the unprocessed rendering task can be distinguished conveniently.
The embodiment provides a map rendering method for a single-page application, which determines whether a calling interface corresponding to the map application exists in a storage area corresponding to the single-page application when a map calling instruction sent by the single-page application is received; if the calling interface does not exist in the storage area, determining whether a first download task corresponding to the single-page application exists in a preset download task list; and if the first download task exists in the download task list, waiting for the execution of the first download task until the first download task is completed, and calling the downloaded calling interface to process a plurality of rendering tasks in the single-page application. In this way, the embodiment only sends the download request of calling the interface once for a plurality of rendering tasks in the single-page application, the mode of processing the plurality of rendering tasks by downloading one calling interface replaces the mode of processing the plurality of rendering tasks by downloading the plurality of calling interfaces, the problem that partial map rendering fails in the single-page application due to interruption of the download request of the calling interface of one rendering task is avoided, the map rendering effect of the single-page application is improved, the user experience is improved, and the technical problem that the map rendering effect of the existing single-page application is poor is solved.
Referring to fig. 3, fig. 3 is a flowchart illustrating a map rendering method for a single-page application according to a second embodiment of the present invention.
Based on the foregoing embodiment shown in fig. 2, in this embodiment, after step S20, the method further includes:
step S40, if the first download task does not exist in the download task list, sending a download request through a preset map download common component, generating a second download task of the single-page application download calling interface, and adding a corresponding download task identifier to the second download task;
step S50, when it is detected that the second download task completes downloading, the downloaded call interface is called to process a plurality of rendering tasks in the single-page application.
In this embodiment, if the first download task does not exist in the download task list, that is, the download task does not exist at present, that is, the call interface for completing the download does not exist, and the download task in the download does not exist, a request for downloading the call interface is sent to the server through the preset map download common component, a download task (a second download task) of the single-page application download call interface is newly created, and a corresponding download task identifier is added to the second download task. Therefore, the calling interface is downloaded to the storage area corresponding to the single-page application through the second downloading task, and then the downloaded calling interface is called to process the rendering tasks.
Therefore, when the single-page application does not have a calling interface for completing downloading, whether an interface downloading task in downloading exists in the single-page application is further judged, if not, an interface downloading task is newly established, and the downloading calling interface carries out processing on a plurality of rendering tasks. Therefore, repeated downloading of the calling interface is avoided, not only is the downloading task prevented from being interrupted, but also resource waste caused by repeated downloading of the calling interface is avoided.
Referring to fig. 4, fig. 4 is a flowchart illustrating a map rendering method for single-page application according to a third embodiment of the present invention.
Based on the foregoing embodiment shown in fig. 3, in this embodiment, after step S10, the method further includes:
step S60, if the calling interface exists in the storage area, the calling interface is called to process multiple rendering tasks in the single-page application, so as to avoid repeated downloading of the calling interface.
In this embodiment, if the calling interface exists in the storage area corresponding to the single-page application, the map application is directly called through the calling interface to sequentially process the rendering tasks, and rendering of the map of each area in the single-page application page is completed, so that repeated downloading of the calling interface is avoided, and resource waste is reduced.
