The above content is a small compilation for you to share the browser to detect access to the Web page rendering engine, platform, Windows operating system, mobile devices and game system, all the description, I hope you like. The following article to introduce the JavaScript learning notes of the detection client type is (engine, browser, platform, operating system, mobile device), please pay attention to.
