//Parent.js
class Parent extends React.Component {
    constructor() {
        super();
        this.state = {
            name: 'zhangsan'
        }
    }

    test() {
        this.setState({
            name: 'lisi'
        })
    }

    render() {
        return (
            <div>
                <button onClick={this.test.bind(this)}>gogo</button>                
                <Sub1 />
            </div>
        )
    }
}

export default Parent

//Sub1.js
class Sub1 extends React.Component {
    componentWillReceiveProps(nextProps) {        
        console.log('componentWillReceiveProps from sub1')
    }

    render() {
        return <div>Sub1x</div>
    }
}

export default Sub1

Parent中加載Sub1時(shí)未設(shè)置props。
點(diǎn)擊按鈕時(shí)，Parent中的state發(fā)生了變化，導(dǎo)致了Sub1中觸發(fā)了componentWillReceiveProps事件，這個(gè)合理嗎？？
