Vue 实时获取屏幕宽高

 

export default { name: 'page-index', data(){ return{ windowWidth: document.documentElement.clientWidth, //实时屏幕宽度
            windowHeight: document.documentElement.clientHeight,   //实时屏幕高度
 } }, methods: { }, // <!--在watch中监听实时宽高-->
 watch: { windowHeight (val) { let that = this; console.log("实时屏幕高度：",val, that.windowHeight ); }, windowWidth (val) { let that = this; console.log("实时屏幕宽度：",val, that.windowHeight ); } }, mounted() { var that = this; // <!--把window.onresize事件挂在到mounted函数上-->
        window.onresize = () => { return (() => { window.fullHeight = document.documentElement.clientHeight; window.fullWidth = document.documentElement.clientWidth; that.windowHeight = window.fullHeight;  // 高
              that.windowWidth = window.fullWidth; // 宽
 })() }; }, }
