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

⑴ according to UserAgent

for mobile browser judgment

1. How to determine whether to use regular match for mobile terminals,

Matches whether the navigator.useragent contains a string applewebkit*****mobile

Android QQ Browser HD version only AppleWebKit

2 Phone language version of the judgment

Use navigator.browserlanguage to derive the Windows Phone language version,
Of course, hateful little mobile language versions also have compatibility differences, compatible with Mozilla, and the AppleWebKit kernel browser to access its language version, which will list Navigator.language

<script type="text/javascript">/** 智能机浏览器版本信息:**/  var browser={    versions:function(){            var u = navigator.userAgent, app = navigator.appVersion;            return {//移动终端浏览器版本信息                 trident: u.indexOf(‘Trident‘) > -1, //IE内核                presto: u.indexOf(‘Presto‘) > -1, //opera内核                webKit: u.indexOf(‘AppleWebKit‘) > -1, //苹果、谷歌内核                gecko: u.indexOf(‘Gecko‘) > -1 && u.indexOf(‘KHTML‘) == -1, //火狐内核                mobile: !!u.match(/AppleWebKit.*Mobile.*/)||!!u.match(/AppleWebKit/), //是否为移动终端                ios: !!u.match(/\(i[^;]+;( U;)?

More special places.

UC Browser does not have an Android header, only return: Linux, here is roughly based on Linux to determine that Android (the premise must be satisfied with the mobile terminal, UC this is satisfied)

Android QQ browser HD test results are: Mac, Safari, this is a pervert, you look at the process of it

3 Web sites that detect browser user-agent information
