In Magento 1.x we can validate individual form field like.

<input class="input-text required-entry" id="name" title="First Name" type="text" name="name" value="" onblur="validate(this)"/>

function validate(id){

In Magento 2.x How can we validate individual form field?

I want to validate only one field from multiple fields in a single form.


You can validate specific field using below code of line.

], function($){
   $( "#new-button" ).click(function() {        
           return false;

NOTE: make sure you have added data-mage-init='{"validation":{}} in form tag.

  • To make it work you will need to wrap the field with in a form: like it is shown in the other answer by Ankit Shah – open-ecommerce.org Nov 28 '17 at 11:30
  • yes, that's I have added in 'NOTE'. – chirag Nov 28 '17 at 12:26
  • Thanks chirag, but in the question it is not form tag at all so is not completely clear specially when the other answer doesn't have any points. – open-ecommerce.org Nov 28 '17 at 12:52

I found this one to work:


More about how it's implemented and used here: https://mage2.pro/t/topic/5504

<form class="form"
      action="<?php Your Action ?>"
      data-hasrequired="<?php /* @escapeNotVerified */ echo __('* Required Fields') ?>"
      enctype="multipart/form-data" >
<input type="text" name="title" id="title" title="<?php /* @escapeNotVerified */ echo __('Title') ?>" class="input-text data-validate="{required:true}"  value=""  />
