对我来说，最好的解决方案是:

$(form).submit(function(e){

   // Get the button that was clicked       
   var submit = $(this.id).context.activeElement;

   // You can get its name like this
   alert(submit.name)

   // You can get its attributes like this too
   alert($(submit).attr('class'))

});

下面的方法似乎更符合我的目的。

首先，对于任何形式:

$('form').click(function(event) {
  $(this).data('clicked',$(event.target))
});

当为表单触发此单击事件时，它只是记录稍后要访问的原始目标(在事件对象中可用)。这是一个相当宽泛的描边，因为它将在表单上的任何地方触发任何单击。欢迎提供优化评论，但我怀疑它永远不会引起明显的问题。

然后，在$('form').submit()中，您可以查询上次点击的内容，例如

if ($(this).data('clicked').is('[name=no_ajax]')) xhr.abort();

如果你不添加.click事件的意思是你不想为这些事件使用单独的处理程序，你可以在一个函数中处理所有的单击(提交):

$(document).ready(function(){
  $('input[type="submit"]').click( function(event){ process_form_submission(event); } );
});

function process_form_submission( event ) {
  event.preventDefault();
  //var target = $(event.target);
  var input = $(event.currentTarget);
  var which_button = event.currentTarget.value;
  var data = input.parents("form")[0].data.value;
//  var which_button = '?';       // <-- this is what I want to know
  alert( 'data: ' + data + ', button: ' + which_button );
}

假设我有这些“提交”按钮:

<button type="submit" name="submitButton" id="update" value="UpdateRecord" class="btn btn-primary">Update Record</button>
<button type="submit" name="submitButton" id="review_info" value="ReviewInfo" class="btn btn-warning sme_only">Review Info</button>
<button type="submit" name="submitButton" id="need_more_info" value="NeedMoreInfo" class="btn btn-warning sme_only">Need More Info</button>

这个"submit"事件处理程序:

 $('#my_form').on('submit', function (e) {
     let x1 = $(this).find("input[type=submit]:focus");
     let x2 = e.originalEvent.submitter.textContent;

两种表达都可以。如果我点击第一个按钮，“x1”和“x2”都返回更新记录。

对我来说，最好的解决方案是:

$(form).submit(function(e){

   // Get the button that was clicked       
   var submit = $(this.id).context.activeElement;

   // You can get its name like this
   alert(submit.name)

   // You can get its attributes like this too
   alert($(submit).attr('class'))

});

这对我来说很管用:

$("form").submit(function() {
   // Print the value of the button that was clicked
   console.log($(document.activeElement).val());
}
