HTML5 pattern for input(mask)

Question

( (0)|(\d{1,3})([\,])(\d{2}))

we would like get pattern for pattern 0 or number format ***,** in input, where * is number. But we cann't find options for this regexp . How syntax will be right in this case?

Thanks!

The space at the beginning is what's causing you trouble.

 <form action="foo.html"> <input type="text" required pattern="((0)|(\\d{1,3})([\\,])(\\d{2}))" /> <button>Submit</button> </form>
