推荐答案

如果要获取在form submit上按下的submit button的ID，可以通过单击的listening进行操作，保存为，然后按access that variable in form submit event handler:
检查下面的代码段

If you want to get the id of pressed submit button on form submit you can do it by listening which one was clicked, save it's id in variable, and then access that variable in form submit event handler:
Check the below snippet

 var subm = "";
 $('input[type="submit"]').click(function(e) {
   subm = e.target.id;
 });


 $("#edit_posting1").on("submit", function(e) {
   e.preventDefault();
   var el = subm;
   alert(el);
 });

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form name="edit_posting1" id="edit_posting1" method="post" action="edit_posting_bk.php" role="form">

  <center>

    <input class="btn btn-home" type="submit" name="publish" id="publish" alt="Publish" value="Preview" />
    <input class="btn btn-home" type="submit" name="save" id="save" onclick="return confirm('Are you sure you want to Submit.')" alt="Save" value="Save" />
    <?php if($disable==t rue){ echo '<input class="btn btn-home" type="submit" name="disable" id="disable" alt="Disable" value="Disable"/>'; }else{ echo '<input class="btn btn-home" type="submit" name="enable" id="enable" alt="Enable" value="Enable"/>'; }
    ?>
  </center>
