从云数据库获取的数据res.data:

1. {_id: "W88iVpL-scb2HabB", collect_type: "poem", poem_author: "王安石", poem_dynasty: "宋代", …}
2. :{_id: "W88ivFw3CBlYln8u",collect_type: "poem", poem_author: "曹操", poem_dynasty: "两汉", …}

转换代码js：

// console.log('[数据库] [查询记录] 成功: ', res.data)

console.log('res.data: ', res.data)

var _collections = new Array()

for (var i = 0; i < res.data.length; i++) {

// console.log(i, res.data[i])

_collections.push(JSON.parse(JSON.stringify(res.data[i])))

}

for (var j = 0; j < _collections.length; j++) {

console.log("_collections["+j+"]="+ _collections[j])

// _collections.push(JSON.parse(res.data[i]))

}

this.setData({

collections:_collections,

})

布局文件wxml：

<view>

<view wx:for="{{collections}}" wx:key="id">

{{item.poem_id}} | {{item.poem_title}} | {{item.poem_author}} | {{item.poem_dynasty}}

</view>

</view>
