javascript - 用高阶组件装饰导入的 React 组件

Question

我知道如何在导出组件之前对其进行装饰，如下所示:

export default ButtonDecorator(MainButton)

但是如果我尝试创建一个索引来导入它并在某些情况下以不同的方式装饰它。它不会起作用。

这是索引的示例:

import MainButton from './main/main_button'
import BackButton from './back/back_button'

import { ButtonDecorator, LinkDecorator } from 'decorators'

export {
    ButtonDecorator(MainButton) as MainButton,
    LinkDecorator(MainButton) as MainHrefButton,
    BackButton
}

以及高阶组件:

import React, { Component } from 'react'

let Btn = InnerComponent => {
    class NewBtn extends Component {

        constructor(props) {
            super(props)
        }

        render() {
                return (
                    <button onClick={this.props.onClick}>
                        <InnerComponent disabled={this.props.disabled} />
                    </button>
                )
        }
    }

    return NewBtn
}

export default Btn

执行此操作的正确方法是什么？

据我所知export需要名称(变量)，而不是函数调用。试试这个:

const ButtonDecoratedMainButton = ButtonDecorator(MainButton);
const LinkDecoratedMainButton = LinkDecorator(MainButton);

export {
    DecoratedMainButton as MainButton,
    LinkDecoratedMainButton as MainHrefButton,
    BackButton
}
