hello I have this field in checkout, I would like use 'mage/validation' to verify if the is true or not.

I tried, but it doesn't work, maybe I didn't understand how it works :

let password = $('[for="customer-password"]').next().find('.input-text').validation('isValid')


<div class="field amcheckout-password required" data-bind="fadeVisible: isPasswordVisible, css: {required: isPassword}"
    style="display: block;"> <label class="label" for="customer-password" style="top: 16px; font-size: 16px;"> <span
            data-bind="i18n: 'Password'">Mot de passe</span></label>

    <input class="input-text mage-error" type="password" name="password" id="customer-password">


Also I added a button

<div class="buttonContinue buttonContinueStepOne"> Continuer</div>

With his js

Add data-validation to the password input field

data-validate="{required:true, 'isValid':true}

So when based on isValid function it will validate the password

Try this

<input class="input-text mage-error" type="password" name="password" data-validate="{required:true, 'isValid':true}" id="customer-password">


Make this disabled by default:

<div class="buttonContinue buttonContinueStepOne" disabled>Continuer</div>

Then add the below code, where condition is if your validation return true

let password = document.getElementsByClassName('buttonContinue');
password.disabled = false;
  • I appended a button with jquery, is it possible to disable this button if form is not valid ?
