validate natural input number with ngpattern

Question

I use ng-pattern=\"/0-9/\" to set price_field do not accept decimal number. But when I input natural number (from 0 to 9999999),

Answer 1

The problem is that your REGX pattern will only match the input "0-9".

To meet your requirement (0-9999999), you should rewrite your regx pattern:

ng-pattern="/^[0-9]{1,7}$/"

My example:

HTML:

  

    
    Not a valid number!
    This field is required!
    
  

JS:

function formCtrl($scope){
  $scope.onSubmit = function(){
    alert("form submitted");
  }
}

Here is a jsFiddle demo.
