using 'intro' in RegExp

hi, is possible to create a regular expression, who will match entire, but return only a part of a string given?

mystring = 'yiha(whatever)';

-i would like, i.e., only extract whatever is written in a between '(' and ')', but if followed with a word 'yiha'


tnx:)

You can try working with this regular expression...


<script type="text/javascript">
<!--//
var mystring = 'yiha(whatever)';
if(/yiha\((.*)\)/.test(mystring)){
alert(RegExp.$1);
}
//-->
</script>
