        $("#register-form").validate({
            rules: {
                regPassword: {
                    required: true,

                },
                Designation: "required",
                IC: {
                    required: true,
                    },
            },
            messages: {
                regPassword: {
                    required: "<br><font color='red'>Enter Your Password</font>",
                    minlength: "<br><font color='red'>Your password must be at least 4 characters long</font>"
                },
                IC: "<br><font color='red'>Enter Your I/C Number</font>",
            },
            submitHandler: function(form) {
                form.submit();
            }
        });


    }
}

//when the dom has loaded setup form validation rules
$(D).ready(function($) {
    JQUERY4U.UTIL.setupFormValidation();
}); })(jQuery, window, document);

Quote OP:

---

Use required: true, number: true, and rangelength: [12, 12] to require only a 12-digit number. See documentation for a list of all methods/rules.

rules: {
    IC: {
        required: true,
        number: true,
        rangelength: [12, 12]
    }
},
