• Why not do $(document).on('click', 'button[type="submit"]', function() { // 'this' is button and form information is still available.. }); – Gavin Commented Oct 11, 2016 at 19:14
• it looks like $(document) should be an id selector for the form – robbmj Commented Oct 11, 2016 at 19:14
• @robbmj Why do you suggest that? – Gavin Commented Oct 11, 2016 at 19:16

Try binding the event to the submit buttons like this:

$('.save_form').on('click', '[type=submit]', function(event) {
  event.preventDefault();
  var submitbutton = $(this).attr('id');
  var formDetails = $(this).closest('form');
  var formID = formDetails.attr('id');
  var fileurl = formDetails.attr('action');
  console.log(submitbutton);
});

<script src="https://ajax.googleapis./ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<form id="new_contact" class="save_form" action="kontaktdetails.php?art='.$_POST['art'].'" method="post">
  <button class="btn" id="submit1" type="submit" name="save_close">Save and close<i class="fa fa-save-right"></i>
  </button>
  <button class="btn" id="submit2" type="submit" name="save_next">Save and next one<i class="fa fa-save-right"></i>
  </button>
</form>

There are many ways to do this, one would be to add an event handler to the buttons, as the click happens before the submit, and then use a class or something to identify which button was clicked inside the submit handler.
That way you'd still catch and prevent submits that wasn't initiated from the buttons.

If you don't need to catch the submit specifically, you could just use an event handler for the buttons instead of the form submit

$(document).on('click', '.save_form button', function() {
    $('.save_form button').removeClass('clicked');
    $(this).addClass('clicked');
});

$(document).on('submit', '.save_form', function(event) {
    event.preventDefault();
    var formID = $(this).attr('id');
    var formDetails = $('#' + formID);
    var fileurl = $(this).attr('action');

    var id = $(this).find('button.clicked').prop('id');
    alert(id)
});

<script src="https://ajax.googleapis./ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form id="new_contact" class="save_form" action="kontaktdetails.php?art='.$_POST['art'].'" method="post">
  <button class="btn" id="submit1" type="submit" name="save_close">Save and close<i class="fa fa-save-right"></i>
  </button>
  <button class="btn" id="submit2" type="submit" name="save_next">Save and next one<i class="fa fa-save-right"></i>
  </button>
</form>

let say you have the form bellow,

<form id="sForm">
      <input type="text" name="toSearch" id="toSearch" />
      <input type="submit" id="mysubmit"/>
 </form>

and you want to retrieve to value when the form is submitted.In my example the id of the input is named "toSearch". Just do the following.

$('#sForm').on("submit",function(e){
var myvar = $('#toSearch').val();
//Now you can do anything you wish with the variable myvar
//  Put more code here.

  e.preventDefault();

});

The value will be retrieved on submit but you can change it to Onclick or any other kind of action.

Hope it will help
