Is that possible?

I already wrote a simple validator that is triggered when the form is submitted.
Can I use the same validator, but it must be triggered right after the input field has been left.

is it possible?

    It would be possible, here is one way to go about it.

    • Add a Javascript onblur event to the form element
    • The onblur call sends an ajax request containing that one field and its value to a ZF action
    • The action calls the validator on that element, or uses Zend_Form::isValidPartial to check the populated element
    • Return a JSON response indicating valid/invalid and optional error message
    • On ajax complete, read the JSON response and update HTML to reflect the result of validation

    Hope that helps.
