Or a single line change: inArray: function( elem, array ) { if(array.indexOf) return array.indexOf(elem); for ( var i = 0, length = array.length; i < length; i++ ) { if ( array[ i ] === elem ) { return i; } } return -1; },
The availability of indexOf is tested every time but I don't think it makes much difference.
