Abstract

Embodiments of the application disclose a synthesis rendering acceleration based webpage updating method and apparatus. The method comprises: establishing a synchronous updating mechanism between a webpage snapshot of a synthesis thread and a webpage snapshot of a kernel thread; when a browser runs a JavaScript dynamic code to change CSS attributes corresponding to layer attributes in a webpage element, correspondingly updating the attributes of a layer, in which the webpage element is located, in the current webpage snapshot of the kernel thread by the kernel thread, and correspondingly updating the attributes of the corresponding layer in the current webpage snapshot of the synthesis thread by the synthesis thread according to the updated webpage snapshot of the kernel thread; and then performing a synthesis operation according to the updated current webpage snapshot to finish the webpage updating. According to the technical scheme provided by the embodiments of the application, the resetting and webpage snapshot copy of the kernel thread and the pre-drawing step of the synthesis thread are reduced, and the processing efficiency of webpage updating and the performance of webpage dynamic display are improved.

Description

technical field [0001] The present invention relates to the technical field of web page rendering, in particular to a method and device for updating web pages based on composite rendering acceleration. Background technique [0002] At this stage, browsers generally adopt a multi-threaded rendering acceleration architecture to make full use of the hardware performance of multi-core CPU (Central Processing Unit, central processing unit) and GPU (Graphic Processing Unit, graphics processing unit), and avoid UI (UserInterface, user interface) thread blocking Cause user operation is not smooth. Among them, composite rendering acceleration uses more rendering acceleration architectures, and improves rendering performance by dividing web pages into multiple layers. Under the composite rendering acceleration architecture, the browser groups all web page elements according to predetermined rules, making them belong to a specific layer, and organizes all layers into a layer tree in a...
