jquery Judge Browser version plugin, jquery-browser.js

First, jquery judge browser version plugin, jquery-browser.js

After jquery 1.9 has deleted the method of judging the browser version:

$.browser.version

The reasons are:

Note: It is not a good idea to detect the browser through the user agent string, and the method will be completely removed in 1.9, but you can use the jquery Migrate (migration) plugin. Or you can try Modernizr.

But what if you want to use it?

Second, the solution:

Copy the following code, save as Jquery-browser.js, add jquery-browser.js under Jquery.js, you can use jquery to delete the browser version of the method of judging.

The attached file is also available for direct download.

(function(jQuery) {if(Jquery.browser)return; Jquery.browser= {}; JQuery.browser.mozilla=false; JQuery.browser.webkit=false; JQuery.browser.opera=false; JQuery.browser.msie=false; varNAGT =navigator.useragent; JQuery.browser.name=Navigator.appname; JQuery.browser.fullVersion= ' +parsefloat (navigator.appversion); JQuery.browser.majorVersion= parseint (navigator.appversion, 10); varNameoffset, Veroffset, IX; //in Opera, the true version was after "Opera" or after "version"        if((Veroffset = Nagt.indexof ("Opera"))! =-1) {JQuery.browser.opera=true; JQuery.browser.name= "Opera"; JQuery.browser.fullVersion= nagt.substring (Veroffset + 6); if((Veroffset = Nagt.indexof ("Version"))! =-1) JQuery.browser.fullVersion= nagt.substring (Veroffset + 8); }          //in MSIE, the true version was after ' MSIE ' in useragent        Else if((Veroffset = Nagt.indexof ("MSIE"))! =-1) {JQuery.browser.msie=true; JQuery.browser.name= "Microsoft Internet Explorer"; JQuery.browser.fullVersion= nagt.substring (Veroffset + 5); }          //in Chrome, the true version was after "Chrome"        Else if((Veroffset = Nagt.indexof ("Chrome"))! =-1) {JQuery.browser.webkit=true; JQuery.browser.name= "Chrome"; JQuery.browser.fullVersion= nagt.substring (Veroffset + 7); }          //in Safari, the true version was after "Safari" or after "version"        Else if((Veroffset = Nagt.indexof ("Safari"))! =-1) {JQuery.browser.webkit=true; JQuery.browser.name= "Safari"; JQuery.browser.fullVersion= nagt.substring (Veroffset + 7); if((Veroffset = Nagt.indexof ("Version"))! =-1) JQuery.browser.fullVersion= nagt.substring (Veroffset + 8); }          //in Firefox, the true version was after "Firefox"        Else if((Veroffset = Nagt.indexof ("Firefox"))! =-1) {JQuery.browser.mozilla=true; JQuery.browser.name= "Firefox"; JQuery.browser.fullVersion= nagt.substring (Veroffset + 8); }          //in the very other browsers, "Name/version" are at the end of the useragent        Else if(Nameoffset = Nagt.lastindexof (') + 1) < (Veroffset =nagt. LastIndexOf (‘/‘)) {jQuery.browser.name=nagt.substring (Nameoffset, Veroffset); JQuery.browser.fullVersion= nagt.substring (Veroffset + 1); if(jQuery.browser.name.toLowerCase () = =jQuery.browser.name. toUpperCase ()) {JQuery.browser.name=Navigator.appname; }          }          //Trim the fullversion string at semicolon/space if present        if(ix = jQuery.browser.fullVersion.indexOf (";"))!! =-1) JQuery.browser.fullVersion=jQuery.browser.fullVersion. Substring (0, ix); if(ix = jQuery.browser.fullVersion.indexOf (""))! =-1) JQuery.browser.fullVersion=jQuery.browser.fullVersion. Substring (0, ix); JQuery.browser.majorVersion= parseint (' + jQuery.browser.fullVersion, 10); if(IsNaN (jQuery.browser.majorVersion)) {jQuery.browser.fullVersion= ' +parsefloat (navigator.appversion); JQuery.browser.majorVersion= parseint (navigator.appversion, 10); } jQuery.browser.version=jQuery.browser.majorVersion;  }) (JQuery); 

In addition, there is another plugin on the internet, the principle is the same. I have not tested, first recorded here:

Jquery.extend ({browser:function()           {              varRwebkit=/(WebKit) \ ([\w.] +)/, Ropera=/(opera) (?:. *version)? [ \/] ([\w.] +)/, Rmsie=/(MSIE) ([\w.] +)/, Rmozilla=/(Mozilla) (?:. * RV: [\w.] +))?/, Browser={}, UA=window.navigator.userAgent, Browsermatch=Uamatch (UA); if(Browsermatch.browser) {Browser[browsermatch.browser]=true; Browser.version=browsermatch.version; }              return{Browser:browser};            },      }); functionUamatch (UA) {UA=ua.tolowercase (); varMatch =rwebkit.exec (UA)||ropera.exec (UA)||rmsie.exec (UA)|| Ua.indexof ("compatible") < 0 &&rmozilla.exec (UA)|| []; return{browser:match[1] | | "", version:match[2] | | "0"              }; }
