Does anybody know how to solve this problem:

i'm trying to add custom field validation. Chrome console does not have any errors.


    function ($) {
        $.validator.addMethod('test-req', function(v) {
            return false;
        }, 'The amount you entered is too low.');


<input class='required test-req' type='text'  data-bind="value: checker" placeholder='Enter the value' minlength='10' maxlength='10'/>

On page loading fire1 always works. But fire2 is never called. What could be a problem here?

take a look at how Magento 2 validations were added in: lib/web/prototype/validation.js That should give you some hints how to add custom validations.

Also take a look here https://magento.stackexchange.com/a/192407/50597

  • The problem is that i did like manual says and it does not work for me. Normally when you press submit button src/lib/web/mage/validation.js:_create function is called. But in my case does not.
