ZF2 validation filter fails on ajax request?

Question

Zend Framework

When sending data by Ajax, by clicking on submit, the input filter does not work (does it not display a message saying that the password in the input is too short or the required field is empty at all)? I can't figure out why

form.find('.js-event-submit').on('click', function(){
        var dataForm = form.serialize();
        $.ajax({
            type: 'POST',
            url: form.attr('action'),
            dataType: 'json',
            data: dataForm,
            success: function(data){
                if(data.completeRegistration) {
                    form.find('.js-event-success').show();
                }
                console.log(data);
            }
        });

        return false;
    });

But there is an interesting feature. If you remove return false, then the filters work, but the page is reloaded when sending

Answer 1

When sending data by Ajax, by clicking on submit, the input filter does not work (does not display a message saying that the password in the input is too short or the required field is empty in general)

And why on earth should error messages be displayed? You should receive these messages with JavaScript and arrange them yourself. What outputs console.log(data);? What does an AJAX request handler return? Hopefully JSON/XML and not HTML?
Not surprising. By removing return false, the submit button starts working in the standard way - it sends a request to the server with a page reload.
