当 props 在 React、Typescript 中可以有多种类型时,如何传递特定的 prop?

How to pass a specific prop when the props can have multiple types in React, Typescript?

具有不同类型数据的道具接口:

interface ResultProp {
    type: string
    data: {} | AProp | BProp | CProp | DProp
}

Cardview 将根据 props.type:

将道具数据传递给相应的组件
const Cardview:React.FC<ResultProp> = (props) => {
    const renderComponent = () => {
        switch(props.type){
            case "aprop":
                return <A {...props.data} />    // Type mismatch here
            // rest of the types ...
        }
    }
    return (
        <div className="cardview">
            {() => renderComponent}
        </div>
    )
}

组件从 Cardview 接收道具:

const A: React.FC<AProp> = (props) => {
    return (
        <div>
        </div>
    )
}

为了让 TypeScript 理解 props.typeprops.data 之间的关系,您需要使用 discriminated union:

type ResultProp = {type: "aprop", data: AProp} | {type: "bprop", data: BProp} | ...;
