How to detect IE 11 with javascript in Asp.net

Question

Hello I want to detect the Browser , IE 8 or more will be appropriate for me. For this i used following code but it fails for IE 11 . For other its detecting properly.

Answer 1

I used the following code recently to detect IE in general and it worked just fine for IE 11 as well

var bs = document.body.style, isIE=false;
if ('msTransition' in bs) {
        isIE = true;
}

The idea is to look for vedor prefix.
