- // A short snippet for detecting versions of IE in JavaScript
- // without resorting to user-agent sniffing
- // ----------------------------------------------------------
- // If you're not in IE (or IE version is less than 5) then:
- // ie === undefined
- // If you're in IE (>=5) then you can determine which version:
- // ie === 7; // IE7
- // Thus, to detect IE:
- // if (ie) {}
- // And to detect the version:
- // ie === 6 // IE6
- // ie > 7 // IE8, IE9 ...
- // ie < 9 // Anything less than IE9
- // ----------------------------------------------------------
- // UPDATE: Now using Live NodeList idea from @jdalton
- var ie = (function(undefined){
- var v = 3,
- div = document.createElement('div'),
- all = div.getElementsByTagName('i');
- while (
- div.innerHTML = '<!--[if gt IE ' + (++v) + ']><i></i><![endif]-->' &&
- all[0]
- );
- return v > 4 ? v : undefined;
- }());
