表单提交jQuery不起作用

第一个错误是您的表单中包含submit作为ID或NAME的任何内容.

The NUMBER ONE error is having ANYTHING with submit as ID or NAME in your form.

重命名表单元素，否则您将无法在表单上调用.submit()，因为Submit方法/处理程序被name/id属性遮盖了.

Rename your form elements, otherwise you cannot call .submit() on the form since the submit method/handler is shadowed by the name/id attribute.

其他几件事:

如前所述，您需要使用比jQuery事件更简单的事件来提交表单

As mentioned, you need to submit the form using a simpler event than the jQuery one

但是您还需要取消对链接的点击

BUT you also need to cancel the clicks on the links

为什么，您有两个按钮?由于您使用jQuery提交表单，因此除非您在click上设置了隐藏字段，否则您将永远不知道单击了两个按钮中的哪个.

Why, by the way, do you have two buttons? Since you use jQuery to submit the form, you will never know which of the two buttons were clicked unless you set a hidden field on click.

<form action="deletprofil.php" id="form_id" method="post">
  <div data-role="controlgroup" data-filter="true" data-input="#filterControlgroup-input">
  <button type="submit" value="1" class="ui-btn ui-shadow ui-corner-all ui-icon-delete ui-btn-icon-right" data-icon="delete" aria-disabled="false">Anlegen</button>
  <button type="submit" value="2" class="ui-btn ui-shadow ui-corner-all ui-icon-delete ui-btn-icon-right" data-icon="delete" aria-disabled="false">Bnlegen</button>
  </div>
</form> 

 $(function(){
    $("#NOlink, #OKlink").on("click", function(e) {
        e.preventDefault(); // cancel default action
        $("#popupDialog").popup('close');
        if (this.id=="OKlink") { 
          document.getElementById("form_id").submit(); // or $("#form_id")[0].submit();
        }
    });

    $('#form_id').on('submit', function(e){
      e.preventDefault();
      $("#popupDialog").popup('open');
    });
});    

从您的评论来看，我认为您确实想这样做:

Judging from your comments, I think you really want to do this:

<form action="deletprofil.php" id="form_id" method="post">
  <input type="hidden" id="whichdelete" name="whichdelete" value="" />
  <div data-role="controlgroup" data-filter="true" data-input="#filterControlgroup-input">
  <button type="button" value="1" class="delete ui-btn ui-shadow ui-corner-all ui-icon-delete ui-btn-icon-right" data-icon="delete" aria-disabled="false">Anlegen</button>
  <button type="button" value="2" class="delete ui-btn ui-shadow ui-corner-all ui-icon-delete ui-btn-icon-right" data-icon="delete" aria-disabled="false">Bnlegen</button>
  </div>
</form> 

 $(function(){
    $("#NOlink, #OKlink").on("click", function(e) {
        e.preventDefault(); // cancel default action
        $("#popupDialog").popup('close');
        if (this.id=="OKlink") { 
          // trigger the submit event, not the event handler
          document.getElementById("form_id").submit(); // or $("#form_id")[0].submit();
        }
    });
    $(".delete").on("click", function(e) {
        $("#whichdelete").val(this.value);
    });
    $('#form_id').on('submit', function(e){
      e.preventDefault();
      $("#popupDialog").popup('open');
    });
});
