Specifically, when the browser acquires the data display request, the data display request is sent to the server so as to receive response information returned by the server. The data display request may be an http request generated according to an http protocol. Correspondingly, the response information returned by the server is http response information. The browser analyzes the response information to obtain an http response header. The browser identifies whether the state of the visualization application is changed, i.e. whether an updated version of the visualization application exists, according to an ETag (Entity Tag) field in the http response header. When the value of the ETag field in the http response header is changed, the visualization application is updated, and an updated version exists. At this time, the browser acquires the visualization application of the updated version in the server and runs the visualization application of the updated version. And when the value of the ETag field in the http response header is not changed, the visualization application is not updated, and no updated version exists. At this time, the browser acquires the visual application from the cache resource and runs the visual application.
In this embodiment, the terminal receives response information returned by the server through the browser, identifies whether the updated version exists in the visual application according to the response information, and accordingly determines whether to acquire the visual application of the updated version from the server or acquire the visual application from the cached resource, and can automatically acquire the visual application of the new version when the new version is released, so that manual pulling of the visual application of the new version is not needed, and automation of releasing the application of the new version is realized.

The vehicle-mounted data may be vehicle-mounted data within a preset time period. The server returns the vehicle-mounted data to the visualization application in the form of character strings, and the visualization application converts the received character strings into index data, namely objects. The index data may include indices of travel speed, mileage, location coordinates, and the like. And rendering the index data, namely rendering a page by the browser to generate a vehicle-mounted image, wherein the vehicle-mounted image is a vehicle-mounted image of continuous multiple frames with chronological order. Each frame is a static picture, the terminal displays the plurality of frames of vehicle-mounted images through visual application, and the plurality of frames of vehicle-mounted images form animation. The page rendering refers to a process of analyzing html (hypertext markup language) by using a rule defined by CSS (Cascading Style Sheets), so as to realize page rendering.
In this embodiment, the terminal converts the vehicle-mounted data into corresponding index data through visual application, and the browser is facilitated to accurately and quickly render the vehicle-mounted data, so that the index data are rendered through the browser, and a vehicle-mounted image is obtained. Because the vehicle-mounted image is obtained by rendering and analyzing the browser, the obtained vehicle-mounted image is more complete, and the accuracy of vehicle-mounted image display is improved.
In one embodiment, the terminal can calculate and combine the index data through a scripting language engine in the browser, and render the index data to obtain the vehicle-mounted image. Specifically, the corresponding positions of the index data are calculated through a script language engine in the browser, so that the index data are combined to obtain a complete vehicle-mounted image, and the complete vehicle-mounted image is displayed on a visual application. The scripting language engine may be a javascript engine.
