Question

我有一个Ajax调用，如下所示

$.ajax({
                    type: "POST",
                    url: "<%= Url.Content("~/Post/GetItems/")%>"  + userId,                             
                    success: function(data) {  
alert(data.rows.lenth)

                    },
                    error:function(response, status, error) { 

                       }               
                });   
[/code]   
and at controller i have

[code]
public JsonResult GetItems(.......)
{
..............
............

  return Json(new {  rows = from tag in Nodes select new { level = tag.Depth } }, JsonRequestBehavior.AllowGet);
}

我可以在所有浏览器中访问data.rows.length 但在chrome data.rows为null

我该怎么做才能解决这个问题？

可能不相关但是尝试这样：

$.ajax({
    type: 'POST',
    url: '<%= Url.Action("GetItems", "Post") %>',
    data: { userId: userId },
    success: function(result) {
        alert(result.rows.length);
    },
    error: function(response, status, error) { 

    }               
});

和

[HttpPost]
public ActionResult GetItems(string userId)
{
    ...
    var rows = from tag in Nodes select new { level = tag.Depth };
    return Json(new { rows = rows }, JsonRequestBehavior.AllowGet);
}

还要确保控制器操作在那里发送一些值。也许首先通过硬编码来确保AJAX调用有效：

[HttpPost]
public ActionResult GetItems(string userId)
{
    return Json(new 
    { 
        rows = new[]
        {
            new { level = 1 },
            new { level = 2 },
            new { level = 3 },
        } 
    }, JsonRequestBehavior.AllowGet);
}
