|

// ----------------------------------------------------------
|
||
// 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, IE10 ...
|
||
// ie < 9 // Anything less than IE9
