方法不是从剃刀视图触发的

我正在使用带有剃刀视图引擎的ASP.NET MVC 3。

我的NewsController中有以下方法:

public JsonResult GetAllNews()
{
   var items = newsService.FindAll();
   var jsonResult = Json(items);

   return jsonResult;
}

在我看来,我想尝试调用此方法来填充我的YUI数据表。我在这个方法的第一行放了一个断点但是没有命中断点。以下是调用此方法的视图中的代码:

var newsDataSource = YAHOO.util.DataSource('@Url.Action("GetAllNews");');

我甚至尝试过:

var newsDataSource = YAHOO.util.DataSource("/News/GetAllNews/");

两者似乎都不起作用。

这是我的数据表代码:

<div id="grdNews"></div>

<script type="text/javascript">
   // News grid
   var newsColumnDefs = [
      { key: "id", label: "Identifier" },
      { key: "title", label: "Title" },
      { key: "body", label: "Body" }
   ];

   //var newsDataSource = YAHOO.util.DataSource('@Url.Action("GetAllNews");');
   var newsDataSource = YAHOO.util.DataSource("/News/GetAllNews/");
   newsDataSource.responseType = YAHOO.util.DataSource.TYPE_JSON;
   newsDataSource.responseSchema = {
      fields: [
         { key: "id" },
         { key: "title" },
         { key: "body" }
      ]
   };

   var myDataTable = new YAHOO.widget.DataTable("grdNews", newsColumnDefs, newsDataSource);
</script>

我做错了什么?

1 个答案:

答案 0 :(得分:1)

不要忘记让此方法也为GET请求返回JSON:

public JsonResult GetAllNews()
{
   var items = newsService.FindAll();
   return Json(items, JsonRequestBehavior.AllowGet);
}

同样设置datasource并不意味着它会调用该方法。也许你的代码中有一些其他部分存在问题。安装FireBug并查看是否发送了AJAX请求。


更新:

现在问题已经澄清,你在谈论YUI数据表,这里有一个完整的例子:

控制器:

public class HomeController : Controller
{
    public ActionResult Index()
    {
        return View();
    }

    public ActionResult GetAllNews()
    {
        var news = new[] 
        {
            new { id = 1, title = "title 1", body = "body 1" },
            new { id = 2, title = "title 2", body = "body 2" },
            new { id = 3, title = "title 3", body = "body 3" },
        };
        return Json(new
        {
            Result = news
        }, JsonRequestBehavior.AllowGet);
    }
}

查看(~/Views/Home/Index.cshtml):

@{
    ViewBag.Title = "Home Page";
}
