ng-pattern is not considering if starting number is zero in angularjs

Question

I have to validate the brazil phone no, in brazil phone can be started with zero and it will be 8 digits I have given <input type="number" name="mobileNo" ng-model="booking.phone" ng-pattern="/^[0-9]{8,8}$/" required placeholder="Phone no">

validation is working fine if i given something like "25869859" But if i have given as "02587895" it is not counting the first number if it is start with zero, it is taking 9 digits what is need is it should take only 8 digits even if i given number starting with zero

It is ionic cordova mobile app if i changed input type as text then the text keyboard will pop up — Gollapalli, May 12 '17 at 11:21

Try change the Quantifier: ^[0-9]{8,9}$

Quantifier - {8,9} Matches between 8 and 9 times

Or if you want to verify 0, try:

 ^0?[0-9]{8,8}$

0? matches the character 0 literally between zero and one times, as many times as possible, giving back as needed
