React.js:在服务器端呈现时不触发handleSubmit或onClick

Her*_*e76 2 javascript node.js express reactjs

我在服务器端呈现所有内容并触发handleSubmit时出现问题.这是源代码:

index.js:

module.exports = require('./app/server');

此代码不会给我一个错误,但不会触发handleSubmit.我认为这是因为它不是由服务器端呈现的.如何在尝试从服务器端呈现页面时触发表单事件handleSubmit？

流程如下:

客户端请求页面
server执行React.renderComponentToString并将html返回给客户端
此时服务器停止做任何事情
页面加载客户端,并运行React.renderComponent
React通过反应通知标记
- 验证校验和
- 如果一切都好,只需添加事件监听器并等待发生的事情
用户可以提交表单,调用handleSubmit

在handleSubmit中,如果你想将一些数据发送到服务器,你可以使用普通的AJAX/WebSockets/etc技术.

检查一下在浏览器和节点中工作的好的http客户端的superagent.
