@ Ajax.BeginForm LoadingElementId不起作用

Question

我在ajax请求中显示加载元素时遇到问题， 任何人都可以帮忙吗？ 这是我的代码

@using (Ajax.BeginForm("Browse", "Item", new {category = "dropDownValue" }, new AjaxOptions{
  InsertionMode = InsertionMode.Replace,
  HttpMethod = "GET",
  LoadingElementId = "loader",
  UpdateTargetId = "divTable"
}))
{
@Html.DropDownListFor(m => category, new SelectList(category), "--select a category--", new { @class = "form-control", onchange="this.form.submit()"})
}


<div id="loader" style="display:none">
    Loading...<img src="~/Content/gears.gif" />
</div>

好吧，我想通了我用onchange ="this.form.submit()"替换了onchange = "$(form).submit()"，我忘了指定我的动作方法应该返回一个PartialView。
