jQuery has one for jQuery objects:
$("div").index( someElement )
> Is there Javascript equivalent of php inArray?
But, no, none exists for a JavaScript Array. However, you can create one easy:
Array.prototype.indexOf = function(obj) {
for ( var i = 0; i < this.length; i++ )
if ( this[i] == obj ) return i;
return -1;
};
and just do something like:
if ( [0,1,2].indexOf(2) >= 0 ) {
// do stuff
}
