Jquery browser Judgment Method
In jquery, the navigator. userAgent. indexOf is used to determine the browser type and perform some processing. If you do not want to use jquery, you can use it if you change the code slightly.
Jquery determines the source code of the browser (jquery1.31 is used as an example)
Js Code:
Copy codeThe Code is as follows:
Var userAgent = navigator. userAgent. toLowerCase ();
// Figure out what browser is being used
JQuery. browser = {
Version: (userAgent. match (/. + (? : Rv | it | ra | ie) [\/:] ([\ d.] +)/) | [0, '0']) [1],
Safari:/webkit/. test (userAgent ),
Opera:/opera/. test (userAgent ),
Msie:/msie/. test (userAgent )&&! /Opera/. test (userAgent ),
Mozilla:/mozilla/. test (userAgent )&&! /(Compatible | webkit)/. test (userAgent)
};

Version --- browser version
Msie ---- IE browser (Microsoft Internet Explorer)
Mozilla-Firefox
Opera-operabrowser
Js Code:
Var userAgent = navigator. userAgent. toLowerCase ();
Browser = {
Version: (userAgent. match (/. + (? : Rv | it | ra | ie) [\/:] ([\ d.] +)/) | [0, '0']) [1],
Safari:/webkit/. test (userAgent ),
Opera:/opera/. test (userAgent ),
Msie:/msie/. test (userAgent )&&! /Opera/. test (userAgent ),
Mozilla:/mozilla/. test (userAgent )&&! /(Compatible | webkit)/. test (userAgent)
}
The call is the same as that of jquery, except that the $ symbol is removed.

Jquery is used to determine the type of the browser. If this method is used only to determine the type of the browser, it is not recommended. It is only recommended when jquery is used, because there is no need to load such a large class library because of such a small function.
It is recommended that you learn about jquery and learn about it.
Main usage: $. browser. ['browser keyword ']
The Code is as follows:
Copy codeThe Code is as follows:
<Script type = "text/javascript">
$ (Function (){
If ($. browser. msie ){
$ (Function () {alert ("this is msie ");});
}
Else if ($. browser. safari)
{
$ (Function () {alert ("this is safari! ");});
}
Else if ($. browser. mozilla)
{
$ (Function () {alert ("this is mozilla! ");});
}
Else if ($. browser. opera)
{
$ (Function () {alert ("this is opera ");});
}

{
$ (Function () {alert ("I don't konw! ");});
