Question

I have a form that, when submitted, goes through the usual e.preventDefault() and sends an ajax request instead. However, if this ajax request returns a certain condition, I want the form to be submitted normally. How do I achieve this?

// Submit handler
$(".reserveer_form").submit(function(event){
  event.preventDefault();

  $.ajax({
    url: $(this).attr("action"),
    data: $(this).serialize(),
    success: function(data) {
      if($(".messagered",data).length > 0){
        var errors = $(".messagered",data);
        $(".gegevens").before(errors);
      } else {
          // SUBMIT THE FORM!
      } 
      
    }
  });

})

Invoke the native submit method on the form, so that it doesn’t trigger the jQuery handler.

$.ajax({
    context: this, // <-- set the context.
    url: $(this).attr("action"),
    data: $(this).serialize(),
    success: function (data) {
        if ($(".messagered", data).length > 0) {
            var errors = $(".messagered", data);
            $(".gegevens").before(errors);
        } else {
            this.submit(); // <-- submit the form
        }
    }
});
