React—封装时组件嵌套

import Nav from '../nav/nav'; // 引一下即可
export default class Pic extends Component {
    render () {
        return (
            <div className="pic">
                <img className="img" src={require('images/1.jpg')} alt=""/>
                <Nav></Nav>
                {/*组件之间互相嵌套*/}
            </div>
        )
    }
}
