使用react+ant design左侧导航默认选中和展开

1.

openKeys={[openKey]}

2.this.state = {

selectedKey: this.props.location.pathname, //选中

openKey: ''" //展开}

3.点击事件

menuClick =e=>{this.setState({selectedKey:e.key})}

4.更新默认状态

componentDidMount(){

const {pathname} = this.props.location;let path = pathname.split('/');

if(pathname.split('/').length>3){path = path[path.length-2];this.setState({openKey:path})}}

5.展开收缩更新状态

onOpenChange = (k) => {

if(k.length>1){this.setState({openKey:k[k.length-1],});}else{this.setState({openKey:'',});}};
