I am using the jQuery.validator.addClassRules method to validate my input fields for numbers. How do I allow my textbox to accept only comma seperated numbers (0,00) and show the default message if incorrect. Incorrect decimal numbers are:

0.00
1.20
2.30

What I have tried:

<pre><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>

1 solution

I'm not sure about JavaScript - I see a number of possibilities

1) (short sighted) .. check if the string representing the number has a '.' in it, ie string.contains('.') sort of thing and reject if found .. it's not a great solution in that it's not flexible

2) validate using a regular expression - allowing '0'-'9' and '.' - this can be changed later if needed
