The normal technique for that kind of validation involves regular expressions. But there's nothing wrong with what you're trying to do.Here's a nifty way of adding a method to the Array object. It does what you want, and you'll find 1001 uses for it besides.

Array.prototype.contains = function (val) {	for (var sub in this) {		if (this[sub] == val) {			return true;		}	}	return false;}// USE IT LIKE THISvar arr = ['Sam','Abdul','Grete'];var person = "Abdul";if (arr.contains(person) ) {	alert ("YES");}
