how to check for valid currency value in javascript?

[wvdba]

Hi.
i have a field in a page that i have to check for validity of currency. i know how to do it in vbscript/asp. but my edit routine is in javascript. the field is populated after user selects another option from a drop-down menu. the field shows up as $20.00
how would i check to see if it is a valid currency field with the $ sign beside it?
thanks.

?! this is the ASP forum, but you want a javascript answer?
you want a client side javascript check on a currecny field?
code snippet?

<script language=javascript>
var s="1s4";
alert(isCurrency(s));
function isCurrency(pInput) {
var re = /^\$?[0123456789\.-]+$/;
return re.test(pInput);
}
</script>
