还是 json 大法好，这种我用过的，适合大表单，好处是利于测试，以及可以赋初值。看下面的定义就晓得了，属性超级多。

```ts
enum Widget {
div,
radio,
radioGroup,
select,
date
}

interface Option {
label: string;
value: string;
}

interface Field {
label: string;
hideLabel?: boolean;
id: string;
type: Function;
hidden: boolean;
labelAsSuffix?: boolean;
defaultValue?: any;
belongsTo?: string;
widget?: Widget;
required?: boolean;
options?: Option[];
fetchMethod?: () => Promise<any>;
delayFetchMethod?: () => Promise<any>;
suffixText?: String;
postMethod?(val: any): any;
fieldSet?: Field[];
close?: boolean;
rest?: object;
}
```

随手定义的分享出来，不过自己写的，别人未必能看懂。
