vue判断滚动条到底部

mounted (){
     addEventListener('scroll', this.handleScroll)//监听函数
     }
methods:{
 handleScroll() {
   //变量scrollTop是滚动条滚动时，距离顶部的距离
   let scrollTop = document.documentElement.scrollTop||document.body.scrollTop;
   //变量windowHeight是可视区的高度
   let windowHeight = document.documentElement.clientHeight || document.body.clientHeight;
   //变量scrollHeight是滚动条的总高度
   let scrollHeight = document.documentElement.scrollHeight||document.body.scrollHeight;
    //滚动条到底部的条件
    if(scrollTop+windowHeight == scrollHeight){
     //你想做的事情
    }
    }
    }
