VueJs 监听 window.resize 方法---窗口变化

mounted() {
        let _this = this;
        window.onresize = ()=>{
            return (()=>{
                this.vscreen.height=document.body.clientHeight+'px'
            })()
        }
}

 

给图片设置成屏幕高度：

<div :style="vscreen"></div>
data() {
    return {
        vscreen: {
            height: '',
          }
    }
},
created() {
   this.vscreen.height=document.body.clientHeight+'px'
},
