Question

This does it incorrectly:
Can jQuery add commas while user typing numbers?

  $('input.number').keypress(function(event){
      if(event.which >= 37 && event.which <= 40){
          event.preventDefault();
      }
      var $this = $(this);
      var num = $this.val().replace(/,/g, '');
      $this.val(num.replace(/(\d)(?=(\d{3})+(?!\d))/g, "$1,"));
  });

I need “1000000” to be “1,000,000” or better with spaces “1 000 000”.

Please help. Thanks.

Answer 1

if you wanted to have something like “1 000 000”, you can change the code to something like this.

  var num = $this.val().replace(/(\s)/g, '');
  $this.val(num.replace(/(\d)(?=(\d{3})+(?!\d))/g, "$1 "));

Hope this helps
