c# - Ajax.BeginForm 部分 View 替换整个页面

Question

我的 MVC 应用程序有一些问题，当我使用按钮(提交)时一切正常，但是如果我使用 onchange，在同一窗口中打开的部分 View 不会替换任何 div，我使用所有我在这里看到的方法，但没有任何帮助，这里是所有代码(任何都不能正常工作)。为什么会这样？

Controller :

public class HomeController : Controller
{
    public ActionResult Index()
    {
        List<string> Year = new List<string>();
        Year.Add("1");
        Year.Add("2");
        Year.Add("3");
        Year.Add("4");
        ViewBag.Years = new SelectList(Year);
        return View();
    }
 public PartialViewResult testt()
    {
        return PartialView();
    }
    [HttpPost]
public PartialViewResult testTwo()
        {
            return PartialView();
        }
}

查看(我在我的页面上包括了所有不显眼的 ajax、microsoft ajax、jquery 和许多其他脚本):

    </div>
</div>
}

@using (Ajax.BeginForm("testTwo", new AjaxOptions { HttpMethod = "POST", UpdateTargetId = "testDiv", InsertionMode = InsertionMode.Replace }))

{
<div>
    <div>
        @Html.DropDownList("Years", (SelectList)ViewBag.Years, new { onchange = "$(this.form).onsubmit()" })
    </div>
    <div>
        @Html.DropDownList("Years", (SelectList)ViewBag.Years, new { onchange = "$(this.form).submit()" })
    </div>
    <div>
        @Html.DropDownList("Years", (SelectList)ViewBag.Years, new { onchange = "this.form.submit()" })
    </div>
    <div>
        @Html.DropDownList("Years", (SelectList)ViewBag.Years, new { onchange = "this.form.onsubmit()" })
    </div>
</div>
}

<div id="testDiv">
    <h4>here i need a partial view</h4>
</div>

谢谢!

你必须包括

@section scripts {
    @Scripts.Render("~/bundles/jqueryval")
}

这在你的页面中，否则它不会工作。像这样尝试，而不是使用脚本标签。
