wxml

<view class=‘case-page‘>
  <view class=‘list-masonry‘>
    <view class=‘item-masonry‘ wx:for="{{note}}">
      <image class="play" src=‘/images/news/play.png‘></image>
      <view class="item-content">
        <image class="videoimg" src=‘{{item.url}}‘ mode=‘widthFix‘></image>
        <text>下载</text>
      </view>
