js文件中数据:

data:{
    imgUrls:[
      \'../../images/slide/banner1.jpg\'
    ],
    contentItems:[
      "../../images/index/01.jpg",
      "../../images/index/02.jpg"
    ],
    aa:[
      {
        id: 1,txt: "ss", src : "../../images/index/01.jpg"
      },
      {
        id: 2,txt: "ssxx", src: "../../images/index/02.jpg"
      }
    ]

}

wxml 中读取数据：

<view class=\'content\'>
    <view class=\'content-item\' wx:for="{{aa}}" id=\'{{index}}\' bindtap=\'\'>
    <image src=\'{{item.src}}\'></image>
    <view class=\'content-item-text\'>
    <text>{{item.txt}}</text>
    </view>
    </view>
</view>
