I have created forms using php and using jquery for validation.What i exactly need is if validation successful on submit button, disable the submit button till submission gets over.Here is my code:
  if(document.location.pathname == "/contact-us"){
            $("#form-contact-user").validate({
                    ignore: [],
                    rules: {
                        name:{
                            required: true
                        },email: {
                            email: true
                        },
                        phne: {
                            phnDash: true
                        },
                        zip: {
                        zipcode: true
                        }
                    },
                    errorPlacement: function(error, element) {
                        if (element.attr("type") == "checkbox") {
                            error.appendTo( element.parent().parent().parent(".form-checkboxes"));
                        }
                        else if (element.attr("name") == "mailing_address") 
                        {
                         error.appendTo(element.parent().parent().parent());
                        }
                        else{
                            error.insertAfter(element);
                        }
                    }
            });
