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 Nov 28, 2017 at 11:30
  • yes, that's I have added in 'NOTE'. Nov 28, 2017 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. Nov 28, 2017 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=""  />
