const app = getApp()

Page({

  /**
   * 页面的初始数据
   */
  data: {
    menu: {
      imgUrls: [
        \'http://gw.alicdn.com/tps/i2/TB19BluIVXXXXX6XpXXN4ls0XXX-183-129.png?imgtag=avatar\',
        \'http://gw.alicdn.com/tps/TB1FDOHLVXXXXcZXFXXXXXXXXXX-183-129.png?imgtag=avatar\',
        \'http://gw.alicdn.com/tps/TB1PlmNLVXXXXXEXFXXXXXXXXXX-183-129.png?imgtag=avatar\',
        \'http://gw.alicdn.com/tps/TB1RN0HMFXXXXXNXpXXXXXXXXXX-183-129.png?imgtag=avatar\',
        \'http://gw.alicdn.com/tps/TB1exaOLVXXXXXeXFXXXXXXXXXX-183-129.png?imgtag=avatar\',
        \'http://img.alicdn.com/tps/TB1GzMJLXXXXXXoXXXXXXXXXXXX-183-129.png\',
        \'http://gw.alicdn.com/tps/i3/TB1Ewu2KVXXXXXkapXXN4ls0XXX-183-129.png\',
        \'http://gw.alicdn.com/tps/TB1cniBJpXXXXataXXXXXXXXXXX-183-129.png?imgtag=avatar\',
        \'http://img.alicdn.com/tps/TB1caopLVXXXXaDaXXXXXXXXXXX-183-129.png\',
        \'http://gw.alicdn.com/tps/i1/TB1c1FMIpXXXXawXpXXN4ls0XXX-183-129.png?imgtag=avatar\'
      ],
      descs: [
        \'聚划算\',
        \'天猫\',
        \'天猫国际\',
        \'外卖\',
        \'天猫超市\',

      ]
    }
  },

  /**

   */
  onLoad: function (options) {

  }
})

2.页面布局

index.wxml

<!--index.wxml-->
<view class="menu-wrp">  
  <!--设定一个item项后，遍历输出-->  
  <view class="menu-list" wx:for="{{menu.imgUrls}}" wx:key="id">  
    <image class="menu-img" src="{{item}}" />  
    <view class="menu-desc">{{menu.descs[index]}}</view>  
  </view>  
</view>  
<view class="gap-1"></view>

3.样式

/**index.wxss**/
.menu-wrp {  
  width:100%;
  margin-top:20rpx;
