Regular Expression

I want to validate a form with only numbers and "$" sign.
so far i know this
currencyValue = which.value;
var re = /^[0-9]*$/;
if (!re.test(currencyValue)) {
alert("Value must be all numberic charcters, non numeric's removed from field!");
field.value = field.value.replace(/D/g,"");
}


but how do I also add the "$" sign as ok?

Ah, got it guys... my Reg Ex should be
/^[0-9\,\.\$]*$/

field.value = field.value.replace(/D/g,"");

That will replace the capital letter D with "" (nothing).

Try

field.value = field.value.replace([^0-9\,\.\$]/gi, "");
