如何在此 Codesandbox 中从 TSX 转换为 JSX

Question

我正在学习 React 和 JavaScript 现在我有了这个 CodeSandbox 但我无法将它转换为 JavaScript React 我已经为 Card 尝试过这个组件：

import React, { useState } from "react";

const Card = props => {
  const [expanded, setExpanded] = useState(false);

  const RenderCard = (className) => {
    return (
      <div
        className={`card ${className}${expanded ? " expanded" : ""}`}
        onClick={() => {
          setExpanded(!expanded);
        }}
      >
        <div className="image">
          <img alt="digger" src={props.image} />
        </div>
        <div className="info">
          <div
            className="bg1"
            style={{ backgroundImage: "url('" + props.image + "')" }}
          />
          <div
            className="bg2"
            style={{ backgroundImage: "url('" + props.image + "')" }}
          />
          <div
            className="bg3"
            style={{ backgroundImage: "url('" + props.image + "')" }}
          />

          <h1>JCB OES System</h1>
          <h2>Report Number #1</h2>
          <h3>Load lifter work area</h3>

          <div className="button">Open</div>
        </div>
      </div>
    );
  };

  return (
    <div className={`card-container${expanded ? " expanded" : ""}`}>
      {expanded && <div className="background" />}
      {<RenderCard className="card1"/>}
      {<RenderCard className="card2"/>}
    </div>
  );
};

export default Card;

我这样显示 Card。很简单，就是点击卡片的时候不像CodeSandbox那样弹出

import Card from "./Card";
import "./styles.scss";

const CreateContent = () => {
 
  return (
    <div className="app">
      <link rel="stylesheet" href="https://use.typekit.net/jli8mqj.css" />

      <Card image="https://www.thetimes.co.uk/imageserver/image/methode%2Fsundaytimes%2Fprodmigration%2Fweb%2Fbin%2Fbeae8dfb-0a41-4f8e-b076-ffd68417287b.jpg?crop=1024%2C683%2C0%2C0&resize=685" />
      <Card image="https://www.virginexperiencedays.co.uk/content/img/product/large/PJCBRA__01.jpg" />
      <Card image="https://www.toyfarmers.co.uk/images/britains-jcb-3cx-backhoe-loader.jpg" />
      <Card image="https://seatylive.blob.core.windows.net/eventimages/2019-Aug-20-Tue_18-37-31-969.png" />
    </div>
  );
};

export default CreateContent;

样式相同，没有变化：我知道 expanded background 设置为 expanded=true 时使用背景的 scss 样式应该生效的钩子，但我得到的只是黑屏。

    }
  }

我错过了什么？

Answer 1

要将您的代码沙盒从 TypeScript 切换到 JavaScript，您只需要：

从“.ts”和“.tsx”文件（接口、类型等）中删除所有 typescript 特定语法
将所有文件扩展名更改为它们的 JavaScript 等效文件，即“.ts”->“.js”和“.tsx”->“.jsx”。
更新“package.json”文件的“main”属性以指向重命名的入口点。即“src/index.jsx”.
