I am currently using this textbox constraint to allow 6 figure numbers with up to 3 decimal places.

<textbox  id="bal" maxlength="11"  constraint="/^[0-9]{1,6}(?:[.][0-9]{1,3})?$/"/>

So I can enter up to 999999.999. However, I want to allow for a $ sign to be entered before the number. How do I add that to the constraint?

How about this? It is optional to enter a dollar sign in front:


if it should always be in front, just remove the "?"
