Angular ng-pattern to allow one dot

Question

How to allow on text input , numbers and one dot using Angular?

I have this on html :

  <input type="text"  ng-pattern="/^[0-9.]*$/" />

But I want to allow just one dot.

Any idea?

you mean this `^[0-9]*\.[0-9]*$` – Avinash Raj May 25 '15 at 11:08 — Avinash Raj, May 25 '15 at 11:08

Seems like you want to allow decimal or integer numbers.

^[0-9]+(?:\.[0-9]+)?$
