实现效果

实现过程

  
  

      正在加载数据
    

js

data() {
  return {
    visibleLoading: false,
  }
},
mounted() {
  //ref指向对应div，不建议对window全局监听，会影响子div的滚动
  this.$refs.container.addEventListener('scroll', this.handleScroll);
},
beforeUnmount() {
  this.$refs.container.removeEventListener('scroll', this.handleScroll);
},
methods:{
  //滚轮监听
  handleScroll() {
    let listAllHeight =
      document.documentElement.scrollTop ||
      document.body.scrollTop + document.documentElement.scrollHeight ||
      document.body.scrollHeight;
    let containerHeight = document.querySelector('#container').scrollHeight;
    //46 + 62 + 75是表格距离页面顶部的剩余距离，跟个人布局有关
    let fieldHeight = document.querySelector('#left-field').scrollHeight + 46 + 62 + 75;
    if (
      (fieldHeight >= containerHeight && this.pageHeight !== fieldHeight) ||
      (containerHeight > fieldHeight && this.pageHeight !== containerHeight)
    ) {
      this.visibleLoading = true;
    }

    setTimeout(() => {
      if (listAllHeight === this.pageHeight && this.pageHeight < containerHeight) {
        this.pageHeight = this.pageHeight + 750;
      }
      if (this.pageHeight > containerHeight && containerHeight > fieldHeight) {
        this.pageHeight = containerHeight;
      }
      if (this.pageHeight > fieldHeight && fieldHeight >= containerHeight) {
        this.pageHeight = fieldHeight;
      }
      this.visibleLoading = false;
    }, 500);
  },
}

css

.loading-bottom {
  position: absolute;
  left: 255px;
  bottom: 0;
  height: 30px;
  padding: 5px 0;
  background-color: #d3dae6;
  width: calc(100% - 270px);
  text-align: center;
  font-size: 14px;
  font-weight: 500;
  border-radius: 2px;
}
