class Home extends React.Component {
constructor(props, context) {
super(props, context)
this.shouldComponentUpdate = PubeRederMixin.shouldComponentUpdate.bind(this)
}
render() {
return (
<div>
<HomeHeader cityName = {this.props.userinfo.cityName}/>
<Category/>
<div style = {{height: '15px'}}></div>
<Ad/>
<List cityName = {this.props.userinfo.cityName}/>
</div>
)
}
}
function mapStateToProps(state) {
return {
userinfo: state.userinfo
}
}这个 userinfo 哪里来的, 我在此页面修改 userinfo 都多导致无法正确获取 cityName
