ASP .NET MVC 3 设计问题（通过 Ajax 加载数据）

发布于 2024-10-21 01:56:42 字数 764 浏览 6 评论 0原文

我有一个类别类别，代表产品类别... 所以我创建了一个视图，显示一个树视图，左侧有我的类别...... 当用户选择 TreeView 节点时，我想在同一页面/视图中显示所有类别数据（右侧）

到目前为止我所做的是通过 Ajax 加载 JQuery TreeView...并在每个 TreeView 上添加了一个单击事件节点... 单击通过 Ajax 调用所选类别，如下所示 (CategoryController)：

    [HttpGet]
    public ActionResult GetCategory(string idCategory)
    {
        if (ModelState.IsValid)
        {
            var _category = _categoryRepository.Get(Convert.ToInt16(idCategory));

            if (Request.IsAjaxRequest())                
                return Json(_category, JsonRequestBehavior.AllowGet);

            return RedirectToAction("Index");
        }

        return View();
    }

因此，我在客户端上获取了类别 JSON，并且必须手动填写所有字段...

这是正确/最佳的方法吗？我错过了什么吗？

到目前为止谢谢

保罗

I have a class Category, that represents products category...
So I created a View that shows a Treeview with my Categories on left ...
When user select a TreeView Node, I´d like to show all the Category data in the same Page/View (On right)

What I did so far is load the JQuery TreeView via Ajax... And added a click event on each TreeView Node...
The click calls, via Ajax, the selected Category, like that (CategoryController):

    [HttpGet]
    public ActionResult GetCategory(string idCategory)
    {
        if (ModelState.IsValid)
        {
            var _category = _categoryRepository.Get(Convert.ToInt16(idCategory));

            if (Request.IsAjaxRequest())                
                return Json(_category, JsonRequestBehavior.AllowGet);

            return RedirectToAction("Index");
        }

        return View();
    }

So, I got the Category JSON on client, and have to manually fill all the fields ...

Is that the right/best way to do that?
Am I missing something?

Thanks so far

Paul

如果您使用 JSTree，则可以使用 JSON_DATA 插件从服务器返回 JSON 数据，并让 JSTree 为您构建节点。我不知道您的 _category 对象是什么样的，但文档提供了 JSTree 期望的结构。

{ 
    data : "node_title", 
    // omit `attr` if not needed; the `attr` object gets passed to the jQuery `attr` function
    attr : { id : "node_identificator", some-other-attribute : "attribute_value" }, 
    // `state` and `children` are only used for NON-leaf nodes
    state: "closed", // or "open", defaults to "closed"
    children: [ /* an array of child nodes objects */ ]
}

如果您无法以这种格式返回数据，那么您必须像现在一样手动渲染树节点。

我希望这有帮助！

If you're using JSTree, you can use the JSON_DATA plugin to return JSON data from your server and have JSTree build your nodes for you. I don't know what your _category object looks like, but the documentation provides the structure that JSTree expects.

{ 
    data : "node_title", 
    // omit `attr` if not needed; the `attr` object gets passed to the jQuery `attr` function
    attr : { id : "node_identificator", some-other-attribute : "attribute_value" }, 
    // `state` and `children` are only used for NON-leaf nodes
    state: "closed", // or "open", defaults to "closed"
    children: [ /* an array of child nodes objects */ ]
}

If you can't return data in this format, then you'll have to render the tree nodes manually as you're doing it now.

I hope this helps!
