Determine the browser's kernel and version number method Rollup _jquery

Using jquery to determine the kernel and version number of the browser

Copy Code code as follows:

<script type= "Text/javascript" >
$ (function () {
if ($.browser.msie && ($.browser.version = = "7.0")) {
$ ("#yourannet"). CSS ("Margin-left", "10px");
}//ie7 Browser
else if ($.browser.msie && ($.browser.version = = "6.0") &&!$.support.style) {
$ ("#yourannet"). CSS ("Margin-left", "15px");
}//ie6 Browser
else if ($.browser.msie && ($.browser.version = = "8.0")) {
$ ("#yourannet"). CSS ("Margin-left", "20px");
}//IE8 Browser
else if ($.browser.msie && ($.browser.version = = "9.0")) {
$ ("#yourannet"). CSS ("Margin-left", "25px");
}//IE9 browser
else if (Window.navigator.userAgent.toLowerCase (). IndexOf ("360SE") >= 1) {
$ ("#yourannet"). CSS ("Margin-left", "30px");
}//360 Browser
})

JQuery uses the regular to match useragent to determine the type and version of the browser . What if we're going to judge whether the current browser is IE6?

Copy Code code as follows:

$ (function () {
if ($.browser.msie) {
Alert ("This is Msie");
}
else if ($.browser.safari)
{
Alert ("This is safari!");
}
else if ($.browser.mozilla)
{
Alert ("This is mozilla!");
}
else if ($.browser.opera) {
Alert ("This is opera");
}
else {
Alert ("I don ' t konw!");
}

The following is a regular expression of jquery: support for distinguishing ie, Firefox, opera, Chrome, Safari

Copy Code code as follows:

Browser Check-----start
var useragent = navigator.useragent,//useragent
Rmsie =/.* (MSIE) ([\w.] +). */,//IE
Rfirefox =/.* (Firefox) \/([\w.] +). */,//Firefox
Ropera =/(opera). +version\/([\w.] +)/,//Opera
Rchrome =/.* (Chrome) \/([\w.] +). */,//Chrome
Rsafari =/.*version\/([\w.] +). * (Safari). */;//Safari
Jmeteor.browser = {};
var ua = Useragent.tolowercase ();
function Uamatch (UA) {
var match = rmsie.exec (UA);
if (match!= null) {
return {browser:match[1]¦¦ "", version:match[2]¦¦ "0"};
}
var match = rfirefox.exec (UA);
if (match!= null) {
return {browser:match[1]¦¦ "", version:match[2]¦¦ "0"};
}
var match = ropera.exec (UA);
if (match!= null) {
return {browser:match[1]¦¦ "", version:match[2]¦¦ "0"};
}
var match = rchrome.exec (UA);
if (match!= null) {
return {browser:match[1]¦¦ "", version:match[2]¦¦ "0"};
}
var match = rsafari.exec (UA);
if (match!= null) {
return {browser:match[2]¦¦ "", version:match[1]¦¦ "0"};
}
if (match!= null) {
return {browser: "", Version: "0"};
}
}
var browsermatch = Uamatch (Useragent.tolowercase ());
if (Browsermatch.browser) {
Jmeteor.browser[browsermatch.browser] = true;
Jmeteor.browsername = Browsermatch.browser;
JMeteor.browser.version = browsermatch.version;
JMeteor.browser.language = (navigator.language? navigator.language
: navigator.userlanguage¦¦ "");
}
Browser Check-----End
　　　　
　　　　　
How to use:
JavaScript code
JMeteor.browser.msie//Determine if IE is, return true to represent
Jmeteor.browsername//Browser name
JMeteor.browser.version//Browser version
JMeteor.browser.language//language
</script>

Using browser version information to determine the browser

Copy Code code as follows:

var _uat=navigator.useragent;
if (_uat.indexof ("MSIE 6.0") >0) alert ("IE6");
else if (_uat.indexof ("MSIE 7.0") >0) alert ("IE7");
else if (_uat.indexof ("MSIE 8.0") >0) alert ("IE8");
else if (_uat.indexof ("Firefox") >0) alert ("Firefox");

CSS to judge the browser

Copy Code code as follows:

#example {color:red;}/*firefox*/
* HTML #example {color:blue;}/*ie6*/
*+html #example {Color:green}/*ie7*/

HTML Judgment Browser

Copy Code code as follows:

1. <!--[if! ie]><!--> can recognize <!--<! except IE [endif]-->
2. <!--[if ie]> all IE identifiable <! [endif]-->
3. <!--[if IE 6]> only IE6 identifiable <! [endif]-->
4.<!--[If Lt IE 6]> IE6 and IE6 The following versions can be identified <! [endif]-->
5. <!--[if GTE IE 6]> IE6 and IE6 above versions can be identified <! [endif]-->
6.<!--[If IE 7]> only IE7 identifiable <! [endif]-->
7. <!--[if Lt IE 7]> IE7 and IE7 The following versions can be identified <! [endif]-->
8. <!--[if GTE IE 7]> IE7 and IE7 above versions can be identified <! [endif]-->
