<script type="text/javascript">
function yourCheckAlgo(formControl,listOfAcceptableNames){
var argLen=arguments.length;
for(var i=1;i<argLen;i++){
var Reg=new RegExp(arguments
,"i");
if(Reg.test(formControl.value)){return true;}
alert("Not acceptable");
formControl.focus();
return false;
</script>
<form>
<p><input type="text"
onchange= "yourCheckAlgo(this,'Tom','Dick','Harry')"
>Gents</p>
<p><input type="text"
onchange= "yourCheckAlgo(this,'Thelma','Louise')" >
Ladies</p>
</form>
