request请求的数据用wx：for循环渲染

success: function (res) {

that.setData({

listData: res.data.StaffDetail

})

}

<block wx:for=“{{listData}}” wx:for-item=“item”>

<view class=“tr”>

<view class=“td-2”>{{item.SubjectPname}}</view>

<view class=“td-2”>{{item.Price}}</view>

<view class=“td-2”>{{item.SubTotal}}</view>

<view class=“td-2”>{{item.Number}}</view>

</view>

</block>

渲染失败，

res.data.StaffDetail数据是

【

{“SubjectPname”:“技术负责人”,“SubjectName”:null,“Price”:“0.4～0.6”,“SubTotal”:“0.4～0.6”,“Number”:1},

{“SubjectPname”:“中级职称”,“SubjectName”:“结构；材料或化工；（必齐全）”,“Price”:“0.67～0.7”,“SubTotal”:“2～2.1”,“Number”:3}

】

如果这样的话就能渲染成功：

success: function (res) {

that.setData({

listData:

【

{“SubjectPname”:“技术负责人”,“SubjectName”:null,“Price”:“0.4～0.6”,“SubTotal”:“0.4～0.6”,“Number”:1},

{“SubjectPname”:“中级职称”,“SubjectName”:“结构；材料或化工；（必齐全）”,“Price”:“0.67～0.7”,“SubTotal”:“2～2.1”,“Number”:3}

】

})

}

<block wx:for=“{{listData}}” wx:for-item=“item”>

<view class=“tr”>

<view class=“td-2”>{{item.SubjectPname}}</view>

<view class=“td-2”>{{item.Price}}</view>

<view class=“td-2”>{{item.SubTotal}}</view>

<view class=“td-2”>{{item.Number}}</view>

</view>

</block>
