What\'s the least error-prone way to target just IE11 with JavaScript?
Note: This should really only be done for analytics or informing the user what browser they\'r
This will set ie
to the version of IE, or 0 if none. It'll work for 1 through 11, but may not detect future versions if Microsoft drops the Trident engine.
var ie = 0;
try { ie = navigator.userAgent.match( /(MSIE |Trident.*rv[ :])([0-9]+)/ )[ 2 ]; }
catch(e){}

I use the following pattern to target all IE browsers. You can short it down if you only need IE 11.
/msie|trident|edge/g.test(navigator.userAgent.toLowerCase());
Good luck!

Try this,
navigator.sayswho= (function(){
var N= navigator.appName, ua= navigator.userAgent, tem;
var M= ua.match(/(opera|chrome|safari|firefox|msie)\/?\s*(\.?\d+(\.\d+)*)/i);
if(M && (tem= ua.match(/version\/([\.\d]+)/i))!= null) M[2]= tem[1];
M= M? [M[1], M[2]]: [N, navigator.appVersion,'-?'];
return M;
})();
Source from Browser detection in JavaScript?
Updated for IE=11
Use this
var isIE11 = navigator.userAgent.match(/Trident\/7.0; rv 11.0/);

IE11 keeps "Trident" in it's UA string, but drops MSIE. A simple way to detect the browser is IE11 or above (IE12, IE13, etc) is:
var isAtLeastIE11 = !!(navigator.userAgent.match(/Trident/) && !navigator.userAgent.match(/MSIE/));
If you want just IE11 (and you don't want future versions of IE to match), do this:
var isIE11 = !!(navigator.userAgent.match(/Trident/) && navigator.userAgent.match(/rv[ :]11/));
Here's a script you can use to detect any browser:
<script>
// Opera
var isOpera = (!!window.opr && !!opr.addons) || !!window.opera || navigator.userAgent.indexOf(' OPR/') >= 0;
// Firefox 1.0+
var isFirefox = typeof InstallTrigger !== 'undefined';
// Safari 3.0+ "[object HTMLElementConstructor]"
var isSafari = /constructor/i.test(window.HTMLElement) || (function (p) { return p.toString() === "[object SafariRemoteNotification]"; })(!window['safari'] || safari.pushNotification);
// Internet Explorer 6-11
var isIE = /*@cc_on!@*/false || !!document.documentMode;
// Edge 20+
var isEdge = !isIE && !!window.StyleMedia;
// Chrome 1+
var isChrome = !!window.chrome && !!window.chrome.webstore;
// Blink engine detection
var isBlink = (isChrome || isOpera) && !!window.CSS;
if (isFirefox==true) {
alert(isFirefox)
$('.container-fluid').css({"overflow-y":"auto","height":"150%"});
}
</script>
The User-agent string for IE 11 is currently this one :
Mozilla/5.0 (Windows NT 6.3; Trident/7.0; rv 11.0) like Gecko
Windows 10 example:
Mozilla/5.0 (Windows NT 10.0; Trident/7.0; rv:11.0) like Gecko
Which means your can simply test, for versions 11.xx,
var isIE11 = /Trident.*rv[ :]*11\./.test(navigator.userAgent);
As IE10 user agent was
Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.2; Trident/6.0)
it's probably also safe to bet on the fact that now Trident/X
is supposed to be the real versionning.
