项目用vue版本是2.0的,项目中用到es6
首先需要在data里面定义页面的高度
data (){
 return {
 fullHeight: document.documentElement.clientHeight
 }
}把window.onresize事件挂在到mounted
mounted() {
 const that = this
 window.onresize = () => {
 return (() => {
 window.fullHeight = document.documentElement.clientHeight
 that.fullHeight = window.fullHeight
 })()
 }
 }监听window.onresize事件
 watch: {
 fullHeight (val) {
 if(!this.timer) {
 this.fullHeight = val
 this.timer = true
 let that = this
 setTimeout(function (){
 that.timer = false
 },400)
 }
 }
 }这里的定时器是为了优化,如果频繁调用window.onresize方法会造成页面卡顿,增加定时器会避免频繁调用window.onresize方法
