Asp.net mvc ajax更新div

Asp.net mvc ajax更新div,asp.net-mvc,asp.net-ajax,Asp.net Mvc,Asp.net Ajax,控制器操作: public ActionResult Index() { ViewData["sample"] = DateTime.Now.ToLongTimeString(); Thread.Sleep(3000); return View(); } 查看页面: <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server

控制器操作:

    public ActionResult Index()
    {

        ViewData["sample"] = DateTime.Now.ToLongTimeString();
        Thread.Sleep(3000);
        return View();
    }
查看页面:

<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">

<h2>Index</h2>

<div id="divId"><%= Html.Encode(ViewData["sample"])%></div>

 <script type="text/javascript">var event = new Object(); $get("panelOneForm").onsubmit();</script>
 <%using (Ajax.BeginForm("Index", "Proba", new AjaxOptions() { UpdateTargetId = "divId" }, new { id = "panelOneForm" })) { } %>

</asp:Content>

我尝试创建自动更新视图,但失败。怎么了?

您是否导入了microsoft ajax库

<script src="/Content/MicrosoftAjax.debug.js" type="text/javascript"></script>
<script src="/Content/MicrosoftMvcAjax.debug.js" type="text/javascript"></script>

这是一本书。你有萤火虫吗?如果是这样,请尝试查看库是否正确加载,以及在执行时是否检测到错误。您可以在表单中定义一个不可见的提交按钮:

<div id="divId"></div>

<%using (Ajax.BeginForm("Index", "Proba", new AjaxOptions() { UpdateTargetId = "divId" })) { %>
    <input type="submit" id="btnSubmit" style="display:none;" />
<% } %>

<script type="text/javascript">
    // Make sure you put this script after the form
    // so that the button is loaded into the DOM before
    // manipulating it
    $get("btnSubmit").click();
</script>

我在MisrosoftAjax.debug.js上遇到此错误:Sys.ArgumentTypeException:类型为“Sys.\u Application”的对象无法转换为类型为“Sys.\u Application”。参数名称:实例[Break on this error]if!this.isInstanceofTypeInstance…e',Object.getTypeinstance,this;页面中是否有其他正在进行调用的ajax?你在web.config中引用了脚本吗?我在site.masterIn web.config中引用了脚本我有这样一个:奇怪的是,你在mvc中引用了这个脚本。我想不出来。我会使用jquery,很抱歉,我会尝试使用您的代码,但问题仍然存在,日期和时间不会自动更新$getbtnSubmit.click;只点击一次,why@Ognjen,可能是因为您只调用了一次。我将如何使用setInterval函数调整为每10秒调用一次ie自动刷新:window.setIntervalfunction{$getbtnSubmit.click;},10000;
public ActionResult Index()
{
    // You probably want to remove the next line before shipping your
    // application in production as it is not good to stall the thread for 3s
    Thread.Sleep(3000);
    return Content(DateTime.Now.ToLongTimeString(), "text/plain");
}
