Validate fields using JQuery validation without any submit?

I have a HTML5 web application with numerous user-entered fields, and I would like to do some client-side validation on those fields in javascript before sending them to the server. Easy right? Just use JQuery validation plugin ---

But there's a catch. My web app has no forms. There is no submit anywhere in the HTML. Instead there's a JQuery change handler on every user-changeable element, and when the user changes the value of one of those element, an AJAX call is made. (This nonstandard user interaction architecture makes sense for this application.)

I would like to validate the field before the AJAX call, and use the JQuery validation plugin to do that. But I can't figure out how.

Is it possible to use the JQuery validation plugin without a submit anywhere? How would I do this? Or is another approach better?

Firstly, and most importantly, you must wrap your input elements inside <form></form> tags for the jQuery Validate plugin to operate. However, a submit button is not required.

Secondly, you can programatically trigger the validity test of any or all elements without a submit button by using the .valid() method.

$(document).ready(function() {

    $('#myform').validate({  // initialize the plugin on your form.
        // rules, options, and/or callback functions

    // trigger validity test of any element using the .valid() method.

    // trigger validity test of the entire form using the .valid() method.

    // the .valid() method also returns a boolean...
    if ($('#myform').valid()) {
        // something to do if form is valid



jQuery Validation Without Form Submit, I am doing validation to my input fields using jquery validation plugin. inside a form tag and accessing it in jquery like, $("#formID").validate() --> this is working fine. My need is to achieve it without using a form. just DIV. There are two types of validation: client side validation and server side validation. In client side validation the data is validated in the browser using JavaScript before submitting the data to the server. For example, suppose your user submits the form without entering a mandatory field. If you validate the form using jQuery, you can notice this and alert the user to their mistake instead of submitting the form.

You will have to wrap your fields within a form to use the validation plugin and it's a good practice anyway. Also, you can invoke the plugin's validation programmatically and check if the form is valid by doing:

var $form = $('#your_form'),
    validator = $form.validate({...});

//validate the form

//check if the form is valid 
if ($form.valid()) {
    //form is valid

For more options, have a look at the docs.

I've created a little helper. Just add this line of code and then you can use any button anywhere.

$("body [data-submit-form]").on("click", function (event) {
    $("#" + $('submit-form')).valid();

<form id="component-form">


<button data-submit-form="component-form">Button</button>

Explanation: The jquery code listens for all clicks on an element with the attribute 'data-submit-form', in the listener the data-attribute gets extracted and then i trigger the valid method on the matching form.

NOTE: if you want to submit the form if the form is valid use this code:

$("body [data-submit-form]").on("click", function (event) {
    var form = $("#" + $('submit-form'));
    if (form.valid()) {

  • @Sparky, there are several methods that can only be invoked on the validator returned from the validate function, so it's a good idea to keep a reference to it if needed. Also, it's a bad practice to always requery the DOM for getting elements referenced multiple times.
