Front-end multi-process calculation method and system based on Web Worker

Abstract

The invention discloses a front-end multi-process calculation method and system based on Web Worker, and the method comprises the steps: judging whether a current thread is started or not, and transmitting parameters to a background thread in the starting process to create a Worker thread if the current thread is started; calculating data of the currently started threads, and assigning names to each started thread for searching a corresponding relation in a plurality of threads in the background; obtaining the context and access parameters of the execution content of the current thread, and setting a success callback and an error callback; searching the named thread, and binding the named thread with the corresponding context, the access parameter, the successful callback and the wrong callback; and calling corresponding data to successfully callback or falsely callback to a main thread according to a background multi-thread execution result. According to the method and the system, the phenomena of main thread waiting and page false death in the process of executing big data calculation by a javascript single thread can be solved by utilizing multiple threads of a browser, so that the main thread does not need to be blocked.

Description

technical field [0001] The invention relates to the field of Internet technology, in particular to a front-end multi-process computing method and system based on Web Worker Background technique [0002] At present, the front-end of the existing technology needs to deal with the actual DOM due to the particularity of the operating mechanism. Therefore, according to the application scenario, when creating a js oracle, it is determined by innate conditions that it is a single-threaded language, which also leads to the need to use the front-end for large data operations. A performance bottleneck occurs. In order to solve this problem, we can use the multi-threaded mechanism and communication of the browser to effectively solve the phenomenon that the front-end single-threaded computing will cause the page to freeze or freeze. Web Workers provide an easy way for web content to run scripts in a background thread. And a separately opened thread will perform tasks independently an...

AI Technical Summary

Problems solved by technology

[0003] The above-mentioned prior art has the following technical problems: no matter through algorithm optimization or data optimization, it will always enter the main thread of javascript execution, resulting in the inability to execute other programs

Even if the asynchronous solution is used, in the asynchronous execution, there will still be a problem that the execution takes too long to cause a freeze, because other programs need to wait when the main thread is always executed.
