reactjs - 如何在此 Codesandbox 中从 TSX 转换为 JSX
问题描述
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
组件尝试过这个:
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;
我展示了Card
这样的东西。这很简单,只是当我点击一张卡片时,它不会像 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;
样式是相同的,没有变化:我知道expanded background
当设置为expanded=true
使用钩子时,背景的 scss 样式应该生效,但我得到的只是黑屏。

我错过了什么?
解决方案
要将您的代码沙箱从 TypeScript 交换到 JavaScript,您只需要:
- 从“.ts”和“.tsx”文件(接口、类型等)中删除所有打字稿特定的语法
- 将所有文件扩展名更改为其等效的 JavaScript,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”。
我已经创建了一个快速的CodeSandbox。
