WebSharper接口生成器 - 记录

Question

如何定义将序列化为JSON对象的记录...我一直在尝试为YUI2构造函数构建oConfig参数，如：

type TreeParameter =
    {
        Type : string
        Label : string
        Expanded : bool
        Children : TreeParameter array
    }

谢谢！

我想我们可以实现这个，但它还没有进入接口生成器。现在你可以这样做：

let TreeParameter =
    let self = Type.New()
    Pattern.Config "TreeParameter" {
        Required =
            [
                "Type", T<string>
                "Label", T<string>
                "Expanded", T<bool>
                "Children", Type.ArrayOf self
            ]
        Optional = []
    }
    |=> self

从F＃的角度来看，生成的类型将如下所示：

type TreeParameter(t: string, l: string, e: bool, c: TreeParameter[]) =
    member this.Type = t
    member this.Label = l
    member this.Expanded = e
    member this.Children = c

从JavaScript的角度来看，值看起来像这样：

{Type:t,Label:l,Expanded:e,Children:c}

从本质上讲，它就像一个没有记录语法和功能扩展的记录。

WebSharper现已实现此功能。只需使用TSelf。

示例：

let TreeParameter =
    Pattern.Config "TreeParameter" {
        Required =
            [
                "Type", T<string>
                "Label", T<string>
                "Expanded", T<bool>
                "Children", Type.ArrayOf TSelf
            ]
        Optional = []
    }
