Javascript onClick处理程序未向ReactDOMServer.renderToString注册
我正试图模仿这把小提琴： （我也试过这个例子 同样的Javascript onClick处理程序未向ReactDOMServer.renderToString注册,javascript,html,css,node.js,reactjs,Javascript,Html,Css,Node.js,Reactjs,我正试图模仿这把小提琴： （我也试过这个例子 同样的onClick处理程序问题也存在） 并使用ReactDOMServer.renderToString 我接到这个电话： res.send(ReactDOMServer.renderToString(( <html> <head> <link href={'/styles/style-accordion.css'} rel={'

一切都正常，CSS也正常工作，但问题是onClick没有注册。因此，单击手风琴元素没有任何作用。有人知道为什么在这种情况下onClick处理程序可能无法注册吗？React DOM render to string只将初始HTML作为字符串发送，而不发送任何JS。
您还需要一个客户端react路由器，它将根据所需的JS处理程序的react id将其附加到HTML。JS需要在两侧运行。

另一个问题与你的问题相似 所有钩子都不会向ReactDOMServer.RenderToString注册。如果要在react组件上完成服务器端呈现+挂钩，可以将其捆绑到客户端（webpack、gulp等），然后在服务器上使用ReactDOMServer.RenderToString 以下是一篇帮助我实现这一目标的博文：
JS到底在工作吗？有任何JS在客户端工作吗？我认为缺少的一点是，一旦标记到达客户端，我们需要进行更多的React调用来实际绑定处理程序
