所以我在 Codepen 上发现了一位名叫 Sean 的绅士完成的漂亮布局，他使用 React 创建了这个水平 Accordion 。
代码如下但 here如果您需要 fork 的话，就是 Codepen。
所以，我遇到的问题是；如何能够在每个“类别”中使用不同的“项目”。现在所有“类别”都使用相同的“项目”。我相信这很简单，我不理解，但我就是找不到它。
class ProjectList extends React.Component {
createProjectListItem(project) {
let byline = project.acf.project_byline
let client = project.acf.project_client
return (
<li key={'project-' + project.id}>
<a to={'/projects/' + project.slug}>
<h3 className="projectlist--client">{client}</h3>
<h4 className="projectlist--byline">{byline}</h4>
</a>
</li>
);
}
render() {
return (
<div className="project-list">
<ul className="menu vertical">
{ this.props.projects.map( this.createProjectListItem ) }
</ul>
</div>
)
}
}

<div id="root"></div>最佳答案
JSX (JavaScript XML) 无法直接在浏览器中运行。您需要将 JSX 文件转换为纯 JavaScript 才能在浏览器中运行。使用BabelJS为了这。
关于javascript - React - 有人可以做到这一点吗？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/45645743/
