如何在 React 中创建事件？

可以创建一个事件如下：

js
class Display extends React.Component({
show(msgEvent) {
// code
},
render() {
// Here, we render the div with an onClick prop
return (

);
}
});

示例：

js
import React, { Component } from 'react';
class App extends React.Component {
constructor(props) {
super(props);
this.state = {
companyName: ''
};
}
changeText(event) {
this.setState({
companyName: event.target.value
});
}
render() {
return (

);
}
}
export default App;
