I am using jQuery Validator for validations. However for number or digits only the validation not working.

It is accepting special characters also. Instead of letters and special characters I want only digits.

$.validator.addMethod("Length", function(value, element) {
  // var password_regex = this.optional(element) || /^(?=.*[a-z])(?=.*[A-Z])(?=.*\d)(?=.*[@$!%*?&])[A-Za-z\d@$!%*?&]{6,}$/.test(value);
  if ($(element).val() != '' && $(element).val().length !== 20) {
    return false;
  }
  return true;
}, "Please enter exact 20 digit.");

$("#add_form_id").validate({
  rules: {
    rational_id: {
      // number: true,
      Length: true,
      maxlength: 30,
      digits: true,

    },
  }
);

Can you add the markup for your `#add_form_id`? – Peppermintology Oct 20 '20 at 08:14
its working on form submit – jandial nidhi Oct 20 '20 at 08:40
So you actually want to prevent people from even typing a non number into the field prior to submitting the form? If so, [check this question](https://stackoverflow.com/questions/3764821/best-way-to-restrict-a-text-field-to-numbers-only). – Peppermintology Oct 20 '20 at 08:47
use this validation plugin https://cdn.jsdelivr.net/jquery.validation/1.16.0/jquery.validate.min.jsv – Elangovan Selvaraj Oct 20 '20 at 08:47
Stll not working .I am able to add letter and special characters – jandial nidhi Oct 20 '20 at 09:14
Why it's not working ? Any errors? – executable Oct 20 '20 at 09:21
No error occur . Still it taking letters and special characters too.I only want numbers. – jandial nidhi Oct 20 '20 at 10:45
The validation check only happens when the form is submitted. If you want to prevent people even typing non numeric characters you will need to use something like `keydown` events in conjunction with your validation. – Peppermintology Oct 20 '20 at 15:14
