The embodiment of the invention provides a map rendering method for single-page application.
Referring to fig. 2, fig. 2 is a flowchart of 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 of the single page application is applied to a processor or a program for monitoring map call of each page application, and the map rendering method of the single page application includes the following steps:
step S10, when a map calling instruction sent by a single page application is received, determining whether a calling interface corresponding to the map application exists in a storage area corresponding to the single page application;
when the current single-page application renders a plurality of maps, the calling interfaces of the map application are respectively downloaded (i.e. loaded) for each rendering task, and when the success of the downloading of the calling interfaces which are respectively downloaded is monitored, the map application is called through the calling interfaces which are respectively downloaded to process the rendering tasks. However, when the previous rendering task downloads the calling interface, the previous rendering task is easily interrupted by the request of the next rendering task downloading the calling interface, so that the previous rendering task cannot monitor the successful downloading of the calling interface, and the rendering of the previous rendering task fails, and the map rendering corresponding to the rendering task fails.
According to the invention, the mode of processing the plurality of rendering tasks by downloading one calling interface is replaced by the mode of processing the plurality of rendering tasks by the plurality of calling interfaces, so that the problem of poor rendering effect of the single-page application map caused by interruption of the downloading request of the calling interface of one rendering task is avoided.
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 corresponding to the single page application (for example, a file storing data corresponding to the target page application), and if the downloaded call interface exists, the downloaded call interface is not required to be repeatedly downloaded, and the downloaded call interface is directly called to sequentially process a plurality of rendering tasks.
In an exemplary embodiment, the determining whether the call interface corresponding to the map application exists in the storage area corresponding to the single page application specifically includes:
in the memory area, it is determined whether there is an interface identification of the call interface or a variable identification for storing a global variable of the call interface.
In this embodiment, when downloading the call interface is completed, a global variable AMap is defined in a storage area of the single page application, and is used to store the call 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 can be searched in the storage area, the variable identifier of the global variable can 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, the downloaded call interface exists in the storage area. And if the interface identifier of the calling interface does not exist in the storage area, the variable identifier for storing the global variable of the calling interface does not exist, namely 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 downloading task corresponding to the single page application exists or not based on a downloading task identifier in a preset downloading task list;
in this embodiment, before downloading the map call interface, a script element needs to be created for each download task, and a corresponding Identifier (ID) is set for the script element corresponding to each download task. By the method, a corresponding download task identifier (script element ID) is set for each page application corresponding download task, and download data of the page application is recorded through a download task table. The download task list is a record list of download tasks corresponding to the map calling interface, namely, the download tasks corresponding to each page application of the calling interface and the download task identifiers corresponding to each download task are recorded; 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 each 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 identification of the download task of the call interface is further downloaded based on the single page application, the identification is searched in the download task list, and if the identification exists in the download task list, the interface download task (first download task) in the current existing download is indicated.
And step S30, if the first download task exists in the download task list, waiting for 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 embodiment, when the first download task exists in the download task list, it is not necessary to repeatedly trigger a download request of the calling interface, wait for execution of the first download task in the download, and call the calling interface to sequentially process a plurality of rendering tasks when the first download task completes the download of the calling interface. Therefore, when the single page application does not have a call interface for completing downloading, whether the single page application has an interface downloading task in downloading is further judged, and if so, 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 map calling interface downloading, waiting for 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, the download task list indicates that the single page application has sent a download request corresponding to the call interface. That is, in order to avoid abnormal downloading of the calling interface caused by overtime of the downloading task, the downloading time of the downloading task is monitored, for example, the downloading time corresponding to each downloading task is detected according to a preset time interval, if the downloading time does not exceed a preset time threshold, the first downloading task is indicated to be abnormal, and the generated and displayed map calls the prompt information in the interface downloading, so that the user is prevented from repeatedly triggering the downloading instruction, the user experience is improved, and the user is facilitated 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 single page application downloading the calling interface, 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 a plurality of rendering tasks in the single page application.
In this embodiment, when the download time exceeds a preset time threshold, it indicates that the first download task is abnormal, interrupts the abnormal download task (first download task), and then invokes a preset map download public component (a component for downloading a call interface of a map application) to resend a request for downloading the call interface to a server, that is, newly create a download task (a third download task), and add a corresponding identifier to the third download task, so as to search for the third download task based on a download task identifier of the third download task.
Specifically, in order to increase maintainability of the map rendering program, a logic code (such as the map rendering application program) for performing rendering task processing by calling the map application based on the existing single page application is extracted, and the logic code downloaded by the calling interface is packaged into a map downloading common component for sending a downloading request to perform calling interface downloading, and the map downloading common component is used as a preset map downloading common component.
The step of calling the downloaded call interface to process the plurality of rendering tasks in the single page application specifically includes:
acquiring 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 the 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 a rendering task queue, and the downloading of the calling interfaces is monitored to complete or the currently downloaded calling interfaces are detected, and each rendering task in the rendering task queue is sequentially processed through the calling interfaces. A global variable array initampaaray 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 firstly obtained and used as a target rendering task, the calling interface is called, and the map of the corresponding area in the single page application is rendered according to the rendering data corresponding to the target rendering task, so that the 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 finish the processing of each rendering task in the rendering task queue.
In a specific embodiment, when processing of a rendering task is completed, 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 of a single-page application, which is used for determining 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 downloading task corresponding to the single page application exists in a preset downloading task list; and if the first downloading task exists in the downloading task list, waiting for the execution of the first downloading task until the first downloading task is completed, and calling the downloaded calling interface to process a plurality of rendering tasks in the single page application. By means of the mode, the method and the device for processing the single-page application aim at the multiple rendering tasks in the single-page application, only one downloading request of the calling interface is sent, the mode that the multiple rendering tasks are processed by downloading one calling interface is replaced by the mode that the multiple rendering tasks are processed by downloading the multiple calling interfaces, the problem that partial map rendering fails in the single-page application due to the fact that the downloading request of the calling interface of one rendering task is interrupted is avoided, map rendering effect of the single-page application is improved, 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 according to a second embodiment of the present invention.
Based on the 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, a download request is sent through a preset map download public component, a second download task of the call interface is generated for downloading the single page application, and a corresponding download task identifier is added to the second download task;
and step S50, when the second downloading task is detected to finish downloading, the downloaded calling 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, there is no call interface for completing the download at present, and there is no download task in the download, then a request for downloading the call interface is sent to the server through a preset map download public component, a download task (second download task) of a single page application download call interface is newly created, and a corresponding download task identifier is added to the second download task. And then, the downloaded calling interface is called to process a plurality of rendering tasks.
Therefore, when the single page application does not have a call interface with finished downloading, whether the single page application has an interface downloading task in downloading is further judged, if the single page application does not have the interface downloading task, an interface downloading task is newly built, and the downloading call interface processes a plurality of rendering tasks. Therefore, repeated downloading of the calling interface is avoided, not only is the downloading task interrupted avoided, but also resource waste caused by repeated downloading of the calling interface is avoided.
