您可以在react组件中创建函数。实际上是从继承的常规ES6类
React.Component。只要小心，然后将其绑定到正确的上下文即可
onClick：
export default class Archive extends React.Component { saySomething(something) { console.log(something); } handleClick(e) { this.saySomething("element clicked"); } componentDidMount() { this.saySomething("component did mount"); } render() { return <button onClick={this.handleClick.bind(this)} value="Click me" />; }}
