Dynatree ASP.NET MVC：将树发布到服务器

Question

我想通过 ajax 将数据从 dynatree 发布到我的 asp.net mvc 服务器。我使用来自 Steve 的模型类 (Dynatree with ASP.NET MVC)，它们可以很好地从服务器获取数据到客户端。但是我仍然无法将树数据发布到服务器。

客户：

 var td = $("#tree").dynatree("getTree").toDict();
 var json = JSON.stringify(td);

 $.ajax({
        type: "POST",
        url: "/parttree",
        data: json,
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        success: function (response) {
            alert(response);
        }
    });

服务器：

[POST("/parttree")]
public ActionResult TreeData2( List<TreeItem>  ot)
{
    // ot is always null here
}

VS调试器中json的内容： {"title":null,"key":"_1","isFolder":false,"isLazy":true,"tooltip":null,"href":null,"icon":null,"addClass":null ,"noLink":false,"activate":false,"focus":false,"expand":true,"select":false,"hideCheckbox":false,"unselectable":false,"children":[{"标题":"root","key":"_2","isFolder":false,"isLazy":false,"tooltip":null,"href":null,"icon":null,"addClass":null ,"noLink":false,"activate":false,"focus":false,"expand":false,"select":false,"hideCheckbox":false,"unselectable":false,"children":... .

Answer 1

我想说的是：

 $.ajax({
        type: "POST",
        url: "/parttree",
        data: {tree: json},
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        success: function (response) {
            alert(response);
        }
    });

您的 MVC 操作将是：

    [HttpPost]
    public ActionResult PartTree(FormCollection form)
    {
        List<TreeItem> ot =  new JavaScriptSerializer().Deserialize<List<TreeItem>>(form["tree"]);

    }

虽然如果您返回 JSON，您可能会寻找 JsonResult 而不是 ActionResult。
