react 组件的继承，这个错误怎么改？

Question

import React from 'react'

import BaseWin from './baseWindow'

class Win extends BaseWin{
    constructor(props){
        super(props);
        this.state ={
            ...this.props
        };
        console.log(this.name);
        this.common();
    }

    getData(){
        return this.state;
    }

    render(){
        this.state.node.model.set({name:'zhongxia', age:17})
        return(
            <div className="pop-dialog">
                <h2>弹框1</h2>
                <form>
                    <label htmlFor="">用户名：</label><input value={this.state.name} type="text"/>
                    <label htmlFor="">密码：</label><input type="password" value={this.state.password}/>
                </form>
            </div>
        );

    }
}
export default Win;

import React from 'react'
/**
 * 所有弹框的基类
 */
class BaseWin extends React.Component{
    constructor(props){
        super(props);
        this.name ='zhongxia';
        this.state ={};
    }
    common(){
        alert('this is a common function!')
    }
}

export default BaseWin;

Answer 1

this.state.node是undefined， 传入的props有这个node参数吗？

Answer 2

在constructor中要用props而不是this.props

this.state ={
    ...props
};
