Client side validation accept comma separated values

Question

I am using the jQuery.validator.addClassRules method to validate my input fields. How do I allow my textbox to accept only comma seperated values and show the default message if incorrect.

<input type="text" class="form-control numberValidation" />


<!-- JS Plugins Init. -->
<script>
    $(document).on('ready',
        function () {

            $("#signupform").validate({

            errorClass: 'invalid-input'            

        });

        jQuery.validator.addClassRules('numberValidation',
        {
            number: true
        });
    });
</script>

Please share with us an example with valid and invalid input values — adampweb, Dec 15 '20 at 14:32
What inputs would you be considering as invalid? You wouldn't want to invalidate if it doesn't have any commas because if you only had one item, it shouldn't have a comma at the end. — Dan Csharpster, Dec 15 '20 at 15:32
If you wrapped each item in single or double quotes, you could validate that the character inbetween, if there is more than one item, has to be a comma — Dan Csharpster, Dec 15 '20 at 15:38
@ZainNabi, validation is more about what you're going to disallow. You can validate something is a valid date, but often you're validating that its not a negative number, etc. What is somebody tries to send strings with commas and then tries to separate them with semicolons, like: foo,bar;123,,,456;abc;def ? Is that invalid input? I would argue that its fine, it is valid input and just parse it on the commas and let the user see their bad input. Maybe have a preview step before saving the values? — Dan Csharpster, Dec 16 '20 at 14:00
@Dan Csharpster strings are not allowed. Only comma separated numbers are allowed e.g. 0,00 , 1,20 — Zain Nabi, Dec 17 '20 at 02:55

If you combine this answer which shows you how to validate with a regular expression with this answer that contains regex examples for comma separated integers, that should meet your needs.
