Request.IsAjaxRequest从来没有在MVC3返回true [英] Request.IsAjaxRequest never returns true in MVC3

问题描述

我使用的Asp.net MVC3，并尝试做一个简单的Ajax职位，它返回一个局部视图，并在搜索过程中更新我的产品清单的服务器。

I am using Asp.net MVC3 and trying to do a simple Ajax post to the server which returns a partial view and updates my list of items during a search.

    @using (Ajax.BeginForm("PartialUpdate", "Listing"
        , new  AjaxOptions { 
                UpdateTargetId = "ListPartialDiv",
                HttpMethod = "GET",
                InsertionMode = InsertionMode.Replace,

        }))
    {
        <!-- Search Boxes and buttons here -->
    }

    <div id = "ListPartialDiv">
        @{
            Html.RenderPartial("_ListPartial", Model);
         }
    </div>

阿贾克斯成功地将调用服务器和服务器发送一个局部视图来响应。但局部视图总是在一个新的页面呈现。我发现，这是因为它不知道这是一个Ajax调用来了，所以它呈现了新的一页。我已经包含了正确的jQuery ubobtrusive-ajax.min.js脚本，并且增加了密钥，根据如下<一个href="http://stackoverflow.com/questions/5164540/why-doesnt-request-isajaxrequest-work-in-asp-net-mvc-3">This问

    <script src="@Url.Content("~/Scripts/jquery.unobtrusive-ajax.js")" type="text/javascript"></script>
    <script src="@Url.Content("~/Scripts/jquery-1.7.1.min.js")" type="text/javascript"> 

我的控制器code是很简单的：

My controller code is very simple:

      if (Request.IsAjaxRequest())
          return PartialView("_ListPartial", list);

      return View("Index", list);

但Request.IsAjaxRequest（）总是不管返回false。 根据该课题并没有看到在X请求 - 随着头，但我真的不能找出这意味着什么或如何去改变它。我唯一​​能想到的是，我看到每一个其他例子使用的jQuery的旧版本。这是否有什么关系呢？感谢您的帮助。

But Request.IsAjaxRequest() always returns false no matter what. I have also used fiddler and firebug according to This Question and don't see the X-Requested-With header but I can't really figure out what that means or how to change it. The only thing I can think of is that every other example I see uses an older version of jquery. Does that have anything to do with it? Thanks for any help.

推荐答案

您正在包括不显眼，AJAX脚本的jQuery之前，所以没有脚本的工作。

You're including the unobtrusive-AJAX script before jQuery, so none of your scripts are working.
