1. 新建vue文件：scrollMore.vue

<template>
  <div class="scroll_list" :style="{'transform': 'translate3d(0, ' + translateVal + 'px, 0)'}" @touchstart="touchStart" @touchmove="touchMove" @touchend="touchEnd">
    <div class="list_box">
      <slot></slot>
    </div>
    <div v-if="isMoved || loading" :class="showIcon + ' loading'">
      <div class="loading_arrow"></div>
    </div>
  </div>
</template>

<script>
  function scrollY () {
    return window.pageYOffset || window.document.documentElement.scrollTop
  }
  export default {
    props: {
      refresh: {
        type: Boolean,
        default: false
      },
      loading: {
        type: Boolean,
        default: false
      },
      more: {
        type: Boolean,
        default: true
      }
    },
    data () {
      return {
        translateVal: 0,
        firstTouchY: 0,
        isMoved: false,
        showIcon: '',
        triggerDistance: 100,
        isTop: false,
        isBottom: false
      }
    },
    methods: {
      touchStart (ev) {
        if (!this.more && !this.refresh) return
        this.translateVal = 0
        this.firstTouchY = parseInt(ev.changedTouches[0].clientY)
        this.isTop = scrollY() <= 0
        this.isBottom = scrollY() >= (document.body.scrollHeight - document.documentElement.clientHeight)
      },
      touchMove (ev) {
        if (!this.isBottom && !this.isTop) return
        const changeY = parseInt(ev.changedTouches[0].clientY) - this.firstTouchY
        if ((changeY < 0 && this.more) || (changeY > 0 && this.refresh)) {
          this.showIcon = changeY < 0 ? 'refresh_pull_up' : 'refresh_pull_down'
          this.translateVal = changeY < 0 ? -Math.pow(-changeY, 0.85) : Math.pow(changeY, 0.85)
          this.isMoved = true
        }
      },
      touchEnd (ev) {
        if ((!this.isBottom && !this.isTop) || !this.isMoved || (!this.more && !this.refresh)) return
        if (this.translateVal < 0) {
          this.translateVal = 0
          this.$emit('loadMore')
        } else if (this.translateVal >= this.triggerDistance) {
          this.translateVal = 60
          this.$emit('refresh')
        }
        this.showIcon += ' refreshing'
        this.isMoved = false
      },
      scrollY () {
        return window.pageYOffset || window.document.documentElement.scrollTop
      }
    },
    watch: {
      loading: function () {
        if (!this.loading) {
          this.translateVal = 0
          this.showIcon = ''
        }
      }
    }
  }
</script>

2. 在主页面引入并使用新建vue文件

import scrollMore from '@/components/scrollMore'

components: { scrollMore }

data里面定义：

data () {
      return {
        more: false,
        totalPage: 0,
        page: 1,
        list: [],
      }
    },

methods: {
      loadMore () {
        this.page ++
        this.getList(1)
        if (this.page >= (this.totalPage / 5)) this.more = false
      },
      getList (more) {
        this.list = more ? this.list : []
        User.projectList({pageSize: '5', pageNo: this.page}).then(res => {
          if (res.list && res.list.length > 0) this.list.push(...res.list)
          if (this.page === 1) {
            this.more = res.total > 1
            this.totalPage = res.total
          }
        })
      }
    },
