JS Judge Mobile Browser

Original: JS Judge Mobile Browser

Principle of judgment:

JavaScript is the primary language for front-end development, and we can write JavaScript programs to determine the type and version of the browser. JavaScript generally has two ways of judging browser types, one is based on the unique attributes of various browsers, and the other is judged by analyzing the browser's useragent properties. In many cases, after the value of the browser type is determined, you also need to determine the browser version to handle compatibility issues, and the browser version can only be determined by analyzing the browser useragent to know.

Browser type

⑴ Browser-specific properties

⑵ according to UserAgent

Browser version
