react创建组件的三种方式

1 function myComponent(props) { 
2      return 
3         <div>Hello {props.name}</div> 
4 }

 1 var myCreate = React.createClass({
 2     defaultProps: { 
 3         //code
 4     },
 5     getInitialState: function() {
 6         return {
 7             //code
 8         };
 9     },
10     render: function() {
11         return (
12             <div>
13                 //code
14             </div>
15         );
16     }
17 });

class InputControlES6 extends React.Component {
    constructor(props) {
        super(props);
        this.state = {
            state_exam: ‘hello‘
        };

        // ES6 类中函数必须手动绑定
        this.handleChange = this.handleChange.bind(this);
    }

    handleChange() {
        this.setState({
            state_exam: ‘hello world‘
        });
    }

    render() {
        return (
            <div>
                //code
            </div>
        );
    }
};
