這里以搜索歌曲為例：

前端：

<view class="search">    <view class="search-bar">      <view class="search-wrap">          <icon type="search" size="16" class="icon-search" />          <input type="text" placeholder="請輸入搜索內容" class="search-input" name="searchKeyword" bindinput="bindKeywordInpu手機軟件開發
t" value="{{searchKeyword}}" />      </view>      <view class="search-cancel" bindtap="keywordSearch">搜索</view>    </view>    <view class="search-result">      <scroll-view scroll-y="true" bindscrolltolower="searchScrollLower">        <view class="result-item" wx:for="{{searchSongList}}" wx:key="unique"  data-data="{{item}}" >          <view class="icon{{item.isonly=='0' ? ' nocopyright' : ''}}"></view>          <text class="title">{{item.SongName}}--{{item.SingerName}}</text>          <view class="subtitle">            <text>{{item.SingerName}}</text>          </view>        </view>        <view class="loading" hidden="{{!searchLoading}}">正在載入更多...</view>        <view class="loading complete" hidden="{{!searchLoadingComplete}}">已加載全部</view>      </scroll-view>      </view>  </view>

樣式：

page{    display: flex;    flex-direction: column;    height: 100%;  }    /*搜索*/  .search{    flex: auto;    display: flex;    flex-direction: column;    background: #fff;  }  .search-bar{    flex: none;    display: flex;    align-items: center;    justify-content: space-between;    padding: 20rpx;    background: #f4f4f4;  }  .search-wrap{    position: relative;    flex: auto;    display: flex;    align-items: center;    height: 80rpx;    padding: 0 20rpx;    background: #fff;    border-radius: 6rpx;  }  .search-wrap .icon-search{    margin-right: 10rpx;  }  .search-wrap .search-input{    flex: auto;    font-size: 28rpx;  }  .search-cancel{    padding: 0 20rpx;    font-size: 28rpx;  }    /*搜索結果*/  .search-result{    flex: auto;    position: relative;  }  .search-result scroll-view{    position: absolute;    bottom: 0;    left: 0;    right: 0;    top: 0;  }  .result-item{    position: relative;    display: flex;    flex-direction: column;    padding: 20rpx 0 20rpx 110rpx;    overflow: hidden;    border-bottom: 2rpx solid #e5e5e5;  }    .result-item .media{    position: absolute;    left: 16rpx;    top: 16rpx;    width: 80rpx;    height: 80rpx;    border-radius: 999rpx;  }  .result-item .title,  .result-item .subtitle{    overflow: hidden;    text-overflow: ellipsis;    white-space: nowrap;    line-height: 36rpx;  }  .result-item .title{    margin-bottom: 4rpx;    color: #000;  }  .result-item .subtitle{    color: #808080;    font-size: 24rpx;  }  .result-item:first-child .subtitle text{    margin-right: 20rpx;  }  .result-item:not(:first-child) .subtitle text:not(:first-child):before{    content: '/';    margin: 0 8rpx;  }  .loading{    padding: 10rpx;    text-align: center;  }  .loading:before{    display: inline-block;    margin-right: 5rpx;    vertical-align: middle;    content: '';    width: 40rpx;    height: 40rpx;    /* background: url(../../images/icon-loading.png) no-repeat;   */  background-size: contain;    animation: rotate 1s linear infinite;  }  .loading.complete:before{    display: none;  }
