Share the encapsulated js judgment operating system with the browser code and encapsulate the js browser code

Abstract:
The most important task for front-end development is compatibility, system compatibility, browser compatibility, and so on. Today, I will share a method for judging operating systems and browsers encapsulated in my project.

Operating System:

Copy codeThe Code is as follows:
Var OS = (function (){
Var UserAgent = navigator. userAgent. toLowerCase ();
Return {
IsIpad:/ipad/. test (UserAgent ),
IsIphone:/iphone OS/. test (UserAgent ),
IsAndroid:/android/. test (UserAgent ),
IsWindowsCe:/windows ce/. test (UserAgent ),
IsWindowsMobile:/windows mobile/. test (UserAgent ),
IsWin2K:/windows nt 5.0/. test (UserAgent ),
IsXP:/windows nt 5.1/. test (UserAgent ),
IsVista:/windows nt 6.0/. test (UserAgent ),
IsWin7:/windows nt 6.1/. test (UserAgent ),
IsWin8:/windows nt 6.2/. test (UserAgent ),
IsWin81:/windows nt 6.3/. test (UserAgent)
};
}());

To determine whether the system is iPad, you only need to determine if (OS. isIpad ){}.

Browser:
 
Copy codeThe Code is as follows:
Var bw = (function (){
Var UserAgent = navigator. userAgent. toLowerCase ();
Return {
IsUc:/ucweb/. test (UserAgent), // UC Browser
IsChrome:/chrome/. test (UserAgent. substr (-33,6), // Chrome browser
IsFirefox:/firefox/. test (UserAgent), // firefox
IsOpera:/opera/. test (UserAgent), // operabrowser
IsSafire:/safari/. test (UserAgent )&&! /Chrome/. test (UserAgent), // safire Browser
Is360:/360se/. test (UserAgent), // 360 browser
IsBaidu:/bidubrowser/. test (UserAgent), // Baidu Browser
IsSougou:/metasr/. test (UserAgent), // sogou Browser
IsIE6:/msie 6.0/. test (UserAgent), // IE6
IsIE7:/msie 7.0/. test (UserAgent), // IE7
IsIE8:/msie 8.0/. test (UserAgent), // IE8
IsIE9:/msie 9.0/. test (UserAgent), // IE9
IsIE10:/msie 10.0/. test (UserAgent), // IE10
IsIE11:/msie 11.0/. test (UserAgent), // IE11
IsLB:/lbbrowser/. test (UserAgent), // cheetah Browser
IsWX:/micromessenger/. test (UserAgent), // built-in browser
IsQQ:/qqbrowser/. test (UserAgent) // QQ Browser
};
}());

Summary:
Browsers are tested by myself. The problem may be caused by chrome. Most browsers use the WebKit kernel, so I cut chrome navigator out to distinguish it. If the location of chrome navigator Information or the length after chrome is changed in the future, it is easy to see problems. However, it can be seen at present.
