从递归模型创建表单

I have a recursive model like this:

我有一个像这样的递归模型：

public class Node
{
    public int Id { get; set; }
    public string Text { get; set; }
    public IList<Node> Childs { get; set; }

    public Node()
    {
        Childs = new List<Node>();
    }
}

I am building a tree with it withing a razor view by using this code:

我正在使用此代码构建一个带有剃刀视图的树：

<ul>
    @DisplayNode(Model)
</ul>

@helper DisplayNode(Node node) {
    <li>
        @node.Text

        @if(node.Childs.Any())
        {
            <ul>
                @foreach(var child in node.Childs)
                {
                    @DisplayNode(child)
                }
            </ul>
        }
    </li>
}

Everything works fine, my tree renders, but I need to add a textbox on each row of the tree and I want to have to input names like this:

一切正常，我的树呈现，但我需要在树的每一行添加一个文本框，我想要输入这样的名称：

Childs[0].Childs[1].Childs[2].Text

So my model binding will work as expected.

所以我的模型绑定将按预期工作。

Is there any way by using EditorTemplates or anything else to achieve this?

有没有办法使用EditorTemplates或其他任何方法来实现这一目标？

I want to avoid building input names in javascript on the form submit.

我想避免在表单提交的javascript中构建输入名称。

You could use editor templates which respect the current navigational context instead of such @helper.

您可以使用尊重当前导航上下文的编辑器模板而不是@helper。

So define a custom editor template for the Node type ( ~/Views/Shared/EditorTemplates/Node.cshtml):

因此，为Node类型定义一个自定义编辑器模板（〜/ Views / Shared / EditorTemplates / Node.cshtml）：

@model Node
<li>
    @Html.LabelFor(x => x.Text)
    @Html.EditorFor(x => x.Text)
    @if (Model.Childs.Any())
    {
        <ul>
            @Html.EditorFor(x => x.Childs)
        </ul>
    }
</li>

and then inside some main view:

然后在一些主视图中：

@model MyViewModel
<ul>
    @Html.EditorFor(x => x.Menu)
</ul>

where the Menu property is obviously of type Node.

其中Menu属性显然是Node类型。
