基于 Vue.js 的移动端组件库mint-ui实现无限滚动加载更多

beileixinqing 2017-12-22 原文

通过多次爬坑，发现了这些监听滚动来加载更多的组件的共同点，

因为这些加载更多的方法是绑定在需要加载更多的内容的元素上的，

所以是进入页面则直接触发一次，当监听到滚动事件之后，继续加载更多，

所以对于无限滚动加载不需要写首次载入列表的函数，

代码如下：

html:

//父组件

<div v-infinite-scroll="loadMore" infinite-scroll-disabled="loading" infinite-scroll-distance="1000">
          <LifeLists :loadingTextBtn="loadingTextBtn" :loadingText="loadingText" :loadingComplete="loadingComplete" :lifeList="lifeList"></LifeLists>
</div>

//LifeLists组件：

<LifeListItem :lists="lifeList"></LifeListItem>
        <div class="loading-text" v-show="{loadingTextBtn:true}">
          <span v-text="loadingText"></span>
          <mt-spinner v-if="(loadingComplete==false)" type="snake" :size="16"></mt-spinner>
</div>
LifeListItem组件：

<div id="lifeListItemBox">
<router-link v-for="(item,index) in lists" :to="{name:'lifeDetails',params:{id:item.id}}" :key="index">
          <div class="lifeListItem1" v-if="(item.status=='online')">
            <div v-if="(item.hasPrice==true)">
              <div class="title1">{{item.title}}</div>
              <div class="price">
                <b class="now"><span class="unit">{{item.monetaryUnit}}</span>{{item.price}}</b>
              </div>
            </div>
            <div v-else class="title2">{{item.title}}</div>
            <div class="info">
              发布于{{formatTime(item.createAt)}}
              &nbsp;&nbsp;&nbsp;&nbsp;
              {{item.countryName}} {{item.cityName}}
            </div>
            <div class="imageList">
              <img :src="img" alt="" v-for="(img,index) in item.photos">
            </div>
            <div class="content">{{item.detail}}</div>
            <div class="listBar">
              <div class="iconBox">
                <svg class="icon icon-dianzan" aria-hidden="true">
                  <use xlink:href="#icon-dianzan"></use>
                </svg>
                {{item.like}}
              </div>
              <div class="iconBox">
                <svg class="icon icon-pinglun2" aria-hidden="true">
                  <use xlink:href="#icon-pinglun2"></use>
                </svg>
                {{item.commentCount}}
              </div>
            </div>
          </div>
        </router-link>
</div>
