This is the solution used by me and work very well:

// prevent enter key on some elements to prevent to submit the form
function stopRKey(evt) {
  evt = (evt) ? evt : ((event) ? event : null);
  var node = (evt.target) ? evt.target : ((evt.srcElement) ? evt.srcElement : null);
  var alloved_enter_on_type = ['textarea'];
  if ((evt.keyCode == 13) && ((node.id == "") || ($.inArray(node.type, alloved_enter_on_type) < 0))) {
    return false;
  }
}

$(document).ready(function() {
  document.onkeypress = stopRKey;
  // catch the id of submit button and store-it to the form
  $("form").each(function() {
    var that = $(this);

    // define context and reference
    /* for each of the submit-inputs - in each of the forms on
			 the page - assign click and keypress event */
    $("input:submit,button", that).bind("click keypress", function(e) {
      // store the id of the submit-input on it's enclosing form
      that.data("callerid", this.id);
    });
  });

  $("#form1").submit(function(e) {
    var origin_id = $(e.target).data("callerid");
    alert(origin_id);
    e.preventDefault();

  });
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<form id="form1" name="form1" action="" method="post">
  <input type="text" name="text1" />
  <input type="submit" id="button1" value="Submit1" name="button1" />
  <button type="submit" id="button2" name="button2">
    Submit2
  </button>
  <input type="submit" id="button3" value="Submit3" name="button3" />
</form>

Another possible solution is to add a hidden field in your form:

<input type="hidden" id="btaction"/>

Then in the ready function add functions to record what key was pressed:

$('form#myForm #btnSubmit').click(function() {
    $('form#myForm #btaction').val(0);
});

$('form#myForm #btnSubmitAndSend').click(function() {
    $('form#myForm #btaction').val(1);
});

$('form#myForm #btnDelete').click(function() {
    $('form#myForm #btaction').val(2);
});

Now in the form submition handler read the hidden variable and decide based on it:

var act = $('form#myForm #btaction').val();
