主要用到：substring(0, 10)
js:
var that = this wx.request({ url: 'https://xxxxx', headers: { 'Content-Type': 'application/json' }, method: 'GET', success: function(res) { let dataList = res.data.result.data; //获取到数据 dataList.forEach((item) = { item.date = item.date.substring(0, 10); //要截取时间的字符串 }) that.setData({ order: dataList //数据源 }) } }),xml读取：
view class="listBox" wx:for="{{order}}" wx:key='{{item.id}}' text时间：{{item.date}}/text/view小程序
