  1. 引入
    import {Loadmore} from “mint-ui”;
  2. html

    <top-loadmore :distanceIndex="2" :bottom-method="addMoreData" :auto-fill="false" ref="loadmore" :bottomPullText="bottomPullText">
     <div class="list-item" v-for="(item,index) in listArr" :key="index" @click="toRecordDetail(item.user_exchange_id)">
     列表内容
     </div>
    </top-loadmore>
  3. js

    import {Loadmore} from "mint-ui";
    export default {
     components: {"top-loadmore": Loadmore,},
     data(){
         return{
             page_num:1,
             bottomPullText:"上拉加载更多",
         }
     },
      methods:{loadList(){if(_this.page_num!=1){_this.$refs.loadmore.onBottomLoaded();// 这里数据回调胜利之后要从新获取 mt-loadmore 外部的高度, 避免上拉后不复位, 首次申请或查问第一页不执行,避免头部 scroll 遮挡问题
             }
         },
         addMoreData(){if(this.flag) return false
             if (this.totalPageNum > this.page_num) {
                 this.page_num++
                 this.loadList()}
             this.$refs.loadmore.onBottomLoaded();
    // 这里数据回调胜利之后要从新获取 mt-loadmore 外部的高度, 避免上拉后不复位。如果是下拉刷新页面,则须要执行:this.$refs.loadmore.onTopLoaded();},
     },
    }
  4. 上拉过程中容易触发列表点击事件修复
    需批改两个文件:
    \node_modules\mint-ui\lib\mint-ui.common.js
    \node_modules\mint-ui\lib\loadmore\index.js


    批改内容:

    handleTouchEnd: function handleTouchEnd(event) {if (this.direction === 'down' && this.getScrollTop(this.scrollEventTarget) === 0 && this.translate > 0) {event.preventDefault();// 此处为阻止滑动时点击 click,自定义增加
         event.stopPropagation();// 此处为阻止滑动时点击 click,自定义增加
         this.topDropped = true;
         if (this.topStatus === 'drop') {
           this.translate = '50';
           this.topStatus = 'loading';
           this.topMethod();} else {
           this.translate = '0';
           this.topStatus = 'pull';
         }
       }
       if (this.direction === 'up' && this.bottomReached && this.translate < 0) {event.preventDefault();// 此处为阻止滑动时点击 click,自定义增加
         event.stopPropagation();// 此处为阻止滑动时点击 click,自定义增加
         this.bottomDropped = true;
         this.bottomReached = false;
         if (this.bottomStatus === 'drop') {
           this.translate = '-50';
           this.bottomStatus = 'loading';
           this.bottomMethod();} else {
           this.translate = '0';
           this.bottomStatus = 'pull';
         }
       }
       this.$emit('translate-change', this.translate);
       this.direction = '';
    }
