Check if a value is in an Array in jQuery

[javascript]
//jQuery version
jQuery.inArray("value", arr); // Usage: if( jQuery.inArray("value", arr) != -1 ) { true };

//Javascript version
Array.prototype.inArray = function (value) {
var i;
for (i=0; i < this.length; i++) {
if (this[i] === value) {
return true;
}
}
return false;
};

//[1,2,3].inArray(2) > true
//[1,2,3].inArray(22) > false
[/javascript]
