vue 监听屏幕高度的实例

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
