Validating a String

By Raúl | April 6, 2009

well this is a handy code snippet to validate a string
if you want to avoid some bad words, this is for you:

 
function isValid(str:String):Boolean {
        var regExp:RegExp = /\b(badword|nastyWord)\b/i;
	var _isValid:Boolean = !regExp.test(str);
        return _isValid;
}
 
var _inValidMessage = "this is a example for a bad badword it's really nasty";
var _validMessage = "Hello Word!";
 
trace(isValid(_inValidMessage)) //false
trace(isValid(_validMessage))//true

you can add more words just separating them by a pipeline ( | ) in the Regular Expression

Cheers.
