获取dom元素高度的时候，发现是0要加上$nextTick确保dom元素都加载完毕了mounted: function () { this.$nextTick(() => { })}获取距离屏幕可视高度getBoundingClientRect()<div class="tab-main" ref="tabMain"></div> let screenHeight = window.innerHeight // 屏幕高度let

<div class="top" ref="top">mounted () { let topHeight = this.$refs.top.offsetHeight // 头部高度 console.log(topHeight)}

data () { return { windowHeight: window.innerHeight }}mounted () { window.onresize = () => { this.windowHeight = window.innerHeight }}watch: { 'windowHeight': function (newVal, oldVal) { //监听屏幕宽度变化 this.windowHe

也就是红框框的高度window.innerHeight
