jQuery的提交（）是不是叫

Question

我試圖凌駕於提交行爲<form>，所以我用下面的代碼：

<script type="text/javascript"> 
    $(function() { 
     var form = $("#FilterForm"); 

     form.submit(function() { 
      alert("Submit"); 

      $.ajax({ 
       url: form.attr("action"), 
       type: 'POST', 
       data: new FormData(this), 
       processData: false, 
       contentType: false, 
       success: function (response) { 
        alert(response); 
        $('#Container').html(response); 
       }, 
       error: function() { 
        $('#Container').html(loadingFailedStr); 
       }, 
       timeout: 15000 
      }); 

      return false; 
     }) 
    }); 
</script> 

此腳本塊位於我的表後。這種形式的局部視圖聲明：

<div class="panel card-0"> 
    <div class="panel-body"> 
     @using (Html.BeginForm("TasksGridViewPartial", "Tasks", new { StaffId = staffId, StageId = stageId }, FormMethod.Post, new { id = "FilterForm", enctype = "multipart/form-data" }))

我打電話渲染這個@Html.Action("FilterPartial")局部視圖。
最有趣的是，我檢查了form變量在文檔就緒事件，它被宣佈爲需要。但submit仍然沒有被調用。
問題在哪裏？

return false是不夠的，還需要阻止默認：

$(function() { 
     var form = $("#FilterForm"); 

     form.submit(function (e) { // Pass the event to the function 
      e.preventDefault(); // Stop the form submitting. 

      $.ajax({ 
       url: form.attr("action"), 
       type: 'POST', 
       data: new FormData(this), 
       processData: false, 
       contentType: false, 
       success: function (response) { 
        alert(response); 
        $('#Container').html(response); 
       }, 
       error: function() { 
        $('#Container').html(loadingFailedStr); 
       }, 
       timeout: 15000 
      }); 

      return false; 
     }) 
    });
