If you are aware about passing data with ajax, then the work flow is as follows.

1) Send form data through ajax to your controller.

2) Do form validation as of now.

3) If success then "echo" value 1

4) If failure, echo value 0

So that using the value in echo, you can determine whether the validation fails or not. I can give you an example if you need

Sample ajax code

$('#form').on('submit', function(e){
    e.preventDefault();
    var data = $(this).serialize();
    $.ajax({
        url: 'your url',
        type: 'POST',
        data: data,
        success: function(data){
            if(data == 1){
                $('#form')[0].reset();
                alret('success');
            }
            else if(data == 0){
                alret('failed');
            }
        },
        error: function(){
            alert('error');
        }
    });
});
