通过原生vue添加滚动加载更多功能

mounted () {
  window.addEventListener('scroll', this.handleScroll)
},
destroyed () {
  window.removeEventListener('scroll', this.handleScroll)
},

handleScroll () {
    //变量scrollTop是滚动条滚动时，距离顶部的距离
    var scrollTop = document.documentElement.scrollTop||document.body.scrollTop;
    //变量windowHeight是可视区的高度
    var windowHeight = document.documentElement.clientHeight || document.body.clientHeight;
    //变量scrollHeight是滚动条的总高度
    var scrollHeight = document.documentElement.scrollHeight||document.body.scrollHeight;
    //滚动条到底部的条件
    if(scrollTop+windowHeight==scrollHeight &&this.list.length !==0){
      this.loadMore() // 加载的列表数据
    }
  }
