// ---------------------------------------------------------- | |
// A short snippet for detecting versions of IE: | |
// Uses a combination of object detection and user-agent | |
// sniffing. | |
// ---------------------------------------------------------- | |
// If you're not in IE then: | |
// ie === NaN // falsy | |
// If you're in IE 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 | |
// script needs to be wrapped on conditional comments to exclude > ie9 | |
// appends class of "ieX" where X is version number, to document's html element | |
// ie8 demo http://dev.bowdenweb.com/ua/browsers/ie/ie8-detection.html | |
// ie9 demo http://dev.bowdenweb.com/ua/browsers/ie/ie9-detection.html | |
var ie = ( !!window.ActiveXObject && +( /msie\s(\d+)/i.exec( navigator.userAgent )[1] ) ) || NaN; | |
if (ie === 6) { | |
document.documentElement.className+=' ie6'; | |
} else if (ie === 7) { | |
document.documentElement.className+=' ie7'; | |
} else if (ie === 8) { | |
document.documentElement.className+=' ie8'; | |
} else if (ie === 9) { | |
document.documentElement.className+=' ie9'; | |

// ie10 doesn't support conditional comments but it does support @cc_on | |
// @cc_on activates conditional comments within a script | |
// appends class of "ie10" to the document's html element | |
