How to increment number using animate with comma using jQuery?

Question

I'm trying to increment a number inside an element on page. But I need the number to include a comma for the thousandth place value. (e.g. 45,000 not 45000)

<script>
// Animate the element's value from x to y:
  $({someValue: 40000}).animate({someValue: 45000}, {
      duration: 3000,
      easing:'swing', // can be anything
      step: function() { // called on every step
          // Update the element's text with rounded-up value:
          $('#el').text(Math.round(this.someValue));
      }
  });
</script>
<div id="el"></div>

How can I increment a number using animate with comma?

Working Demo http://jsfiddle.net/4v2wK/

Feel free to change it more for your need, you can also look at the currency formatter, Hope this will fit your need :)

Code

// Animate the element's value from x to y:
  var $el = $("#el"); //[make sure this is a unique variable name]
  $({someValue: 40000}).animate({someValue: 45000}, {
      duration: 3000,
      easing:'swing', // can be anything
      step: function() { // called on every step
          // Update the element's text with rounded-up value:
          $el.text(commaSeparateNumber(Math.round(this.someValue)));
      }
  });

 function commaSeparateNumber(val){
    while (/(\d+)(\d{3})/.test(val.toString())){
      val = val.toString().replace(/(\d)(?=(\d\d\d)+(?!\d))/g, "$1,");
    }
    return val;
  }

**output*

Answer 2

You should also add a complete function as such:

step:function(){
    //..
},
complete:function(){
    $el.text(commaSeparateNumber(Math.round(this.someValue)));
}

Answer 3

Had the same problem and used toLocaleString to put commas As suggested in the above answer I found the result deviating from the real value and I solved that by adding the complete callback function that is called when the animation is finished

value_to_be_shown=100000000
// Animate a value from 0 to `value_to_be_shown`
$({
    someValue: 0 // Starting value
}).animate({
    someValue: value_to_be_shown // Ending value
}, {
    duration: 1000, // Animation duration in milliseconds
    easing: 'swing', // Easing function to control acceleration of the animation
    step: function () { // Function to be called on every step of the animation
        // Update the element's text with the rounded-up value of `someValue`:
        $('#el_id').text(Math.round(this.someValue).toLocaleString('en-US'));
    },
    complete: function () { // Function to be called after the animation completes
        // Update the element's text with the final value
        $('#el_id').text(value_to_be_shown.toLocaleString('en-US'));
    }
});
