Method for improving memory of browser

Abstract

The invention relates to the field of web, in particular to a method for improving the memory of a browser, which solves the problem that the memory occupation of the browser cannot be obviously reduced, improves the use of the memory of the browser, and improves the use fluency and the user experience. The invention discloses a method for improving the memory of a browser. The method comprises the following steps: analyzing picture data of a url request; decoding the requested picture data and storing the decoded picture data in a memory; judging an invisible area of the page, and removing nodes in the DOM tree of the invisible area; traversing the removed nodes, and obtaining a corresponding url containing the picture; removing decoded data corresponding to the url in a memory accordingto the obtained corresponding url containing the picture, and associating the url with the corresponding data before decoding; and judging the visual area of the page, and if the original invisible area of the removed node returns to the visual area again, adding the removed node back to the DOM tree again. The method is suitable for improving the browser memory.

Description

technical field [0001] The invention relates to the web field, in particular to a method for improving browser memory. Background technique [0002] With the popularization of web technology, the requirements for browser application performance and user experience are getting higher and higher. As an important performance indicator of browsers, memory usage directly affects browser experience. In the context of more and more web pages today, the image occupation on the page is the main reason for the increase in browser memory usage. Without affecting the function, reducing the memory usage of image data in the browser is decisive for improving user experience. [0003] Too many nodes on a web page will complicate the DOM tree structure and affect the fluency of the page, so the front end needs to remove unnecessary nodes. [0004] Existing technologies such as figure 1 , first create a node with a picture in the DOM tree, request the picture data according to the url, de...
