Method and device for loading JavaScript file as required by domestic CPU

Abstract

The invention relates to the technical field of construction of web sites, in particular to a method for loading JavaScript files as required by a domestic CPU (central processing unit), which comprises the following steps of: firstly, creating a blank HTML5 page, and specifying js files which are only required to be displayed by a first screen and do not contain js files which are required by click login; the method comprises the following steps of: introducing a js file required by first screen loading in an array form according to loadJsFile, calculating a js file feature vector, analyzing each function of the js file, converting a basic unit of a control flow diagram into a vector with a fixed length, extracting a vector with a fixed length as a minimum unit which is equivalent to an element, segmenting the js file into a plurality of elements, the js file is composed of a plurality of elements. Compared with the prior art, the method has the advantages that the unneeded files are not loaded, the needed files are only loaded when needed, repeated loading is avoided, and rapidness is achieved.

Description

technical field [0001] The invention relates to the technical field of building web sites, and in particular provides a method and a device for loading JavaScript files on demand by a domestic CPU. Background technique [0002] With the country's strong support for Xinchuang, the industry has developed rapidly. A number of excellent Xinchuang software and hardware products have emerged in China, which can already meet daily use. More and more Web application software systems based on Xinchuang software and hardware are used in many industries. Put into use. [0003] At present, the loading mode of JS files is blocking loading, that is, the next JS file can be loaded only after the current JS file is completely loaded. Displaying pages in front of users consumes a lot of time. [0004] However, in terms of front-end performance optimization, it has always been traditional optimization, such as: resource merging and compression, the principle of image encoding, and the selec...

Problems solved by technology

[0005] Although these can play a certain role, it is too cumbersome to use a variety of technologies, and the extreme compression of files may cause inconvenience to our use. It is very troublesome to modify the code and decompress it, and then compress it back.
