rated 0 times [ 56] [ 4] / answers: 1 / hits: 19261 / 10 Years ago, fri, june 13, 2014, 12:00:00

Magento has awesome Javascript validation library, which can be initialized var myForm= new VarienForm('[your form id]', true);. However this validation function is triggered when one click on submit button.

Is not there way to validate particular field as you type. For example if I type postal code 2 digit and go to second field, it should instantly validate postal code and show error. As postal code require at least 5 digits.

thanks

Yes, Magento provide awesome validation library. You can call validation for each field with `validate' method.

For example to validate zip code, you can observe blur event and call validate method.

$('billing:postcode').observe('change', function(e){

    Validation.validate($('billing:postcode'))

})

Notice Validation.validate($('billing:postcode')), this will call validation for postcode field.
