IF IE conditional comment in JavaScript?

Question

I need to display a text e.g. "You are using Internet Explorer browser" within the div for all users using IE browsers (6-11). MS has dropped conditional comments as of IE10 so I'm unable to do so via css. Any advice?

Why? IE 10 and 11 are pretty much comparable with other browsers, and versions 6 - 9 can be targeted with conditional comments. — David Thomas, Mar 25 '14 at 00:31
You could do it the old-fashioned way...check `navigator.userAgent` — Matt Browne, Mar 25 '14 at 00:32
@David Thomas For some unknown reasons IE11 is not uploading attachments via php upload. It's working fine with Chrome and Firefox, but not with IE so I thought it's gonna be quicker for me just to put a warning message for IE users :) — user3426374, Mar 25 '14 at 00:35
@Pointy Could be just a temporary fix while he digs out the cause of the problem. — SomeKittens, Mar 25 '14 at 00:43
I think it'd be better, long-term, to find out why it's not working, rather than force your users to switch browsers. — David Thomas, Mar 25 '14 at 00:45
@DavidThomas IE10 and 11 are NOT comparable to other browsers and are still the worst on the planet. — Rob, Mar 25 '14 at 00:50
Feature testing for the particular capabilities you need is a much better alternative. — Jeremy J Starcher, Mar 25 '14 at 02:03

Use navigator.userAgent:

function isIE () {
  var myNav = navigator.userAgent.toLowerCase();
  if( myNav.indexOf('msie') > -1 || myNav.indexOf('.net') > -1) {
    // do stuff;
  }
}

myNav.indexOf('.net') is needed to detect IE 11, all other versions have msie in the UA string.

use ie conditional compilation to target 10/11, which is essentially conditional comments in javascript. you can see a demo here: http://dev.bowdenweb.com/ua/browsers/ie/ie10-detection-via-cc.html
