@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，有人可以帮忙吗？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>

Answer 1

好的，我想通了，我用 onchange = "$(form).submit()" 替换了 onchange ="this.form.submit()" 并且我忘记指定我的操作方法应该 return 一个 PartialView。
