/** Get IE version */
|
|
// ----------------------------------------------------------
|
|
// 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
