how to add a comma automatically after every 3 digits

Hi, thanks for your reply. could you please help me to write a custom mask. I have checked the given link and there are only a few examples and I couldn’t find the one that work for me.

Thanks!

Hi thanks for your reply. This is not what I was looking for. this mask forces me to enter 10 digits with a pattern. what if the user has a random number to enter. he/she should be able to put any value for example 999 OR 74,634 OR 3,333,333. is this something that can be done with masks?

Thanks

Never mind, I figured it out with a JQuery code:

jQuery(document).ready(function( $ ){
  
    // Selecting field e.g "#wpforms-139-field_8"
    $('input#wpforms-139-field_8').on('blur',function(){
       $(this).manageCommas();
    });
  	
  	// replace the field id here as well
    $('input#wpforms-139-field_8').on('focus',function(){
        $(this).santizeCommas();
    });
  
String.prototype.addComma = function() {
  return this.replace(/(.)(?=(.{3})+$)/g,"$1,").replace(',.', '.');
}
//Jquery global extension method
$.fn.manageCommas = function () {
    return this.each(function () {
        $(this).val($(this).val().replace(/(,|)/g,'').addComma());
    });
}

$.fn.santizeCommas = function() {
  return $(this).val($(this).val().replace(/(,| )/g,''));
}
  
});

And thanks for adding this feature for future updates.
