div設置了height:window.innerHeight但窗口變化時不起做用的解決代碼

componentDidMount(){

window.addEventListener('resize',this.onWindowResize());

}

componentWillUnmount(){

window.removeEventListener('resize',this.onWindowResize());

}

onWindowResize(){

let newHeight = window.innerHeight-this.getHeight(100);

setTimeout(() => {

this.setState({containerHeight:newHeight})

},200);

}
