微信小程序实例代码

实现效果：

<view class="container">

  <view class="selection" style="border:0">
  
     <swiper indicator-dots="true"
     autoplay="true" interval="3000" duration="1000">
        <block wx:for="{{imgUrls}}">
           <swiper-item>
              <image src="{{item}}" width="355" height="150"/>
           </swiper-item>
         </block>
      </swiper>
      
   </view>
   
  <view class="selection">
  
    <view class="header">
       <text>精品推荐</text>
       <text class="text-all">全部精品</text>
    </view>
    
    <view class="content">
       <view class="content-item" wx:for="{{contentItems}}">
          <image src="../../images/img1.jpg"/>
             <view class="content-item-text">

      </view>
      
      <view class="list-item" wx:for="{{listItems}}">
      
         <view class="list-item-images">
            <image src="../../images/img2.jpg" class="list-item-images-img"/>        <image src="../../images/avatar.jpeg" class="avatar"/>
         </view>
         
         <view class="list-item-text">

        'https://i.loli.net/2020/02/21/42pTOevfVio1jWs.png',

      ],
      contentItems:['','','',''],
      listItems: ['', '', '', '','', '', '']

总结：
通过几天的学习，我学会了使用view和swiper插件，学会了flew分布，学会了将text的背景颜色设为半透明，学会了编写简单的微信小程序
