## 引入
"datePicker":"../../../components/datePicker/index"

应用

<!-- 时间选择组件 bind:sync 子类回传数据的方法-->
<datePicker wx:if="{{show}}" bind:sync="syncGetDate"></datePicker>

js

 syncGetDate(e){
  let that = this;
  let show = e.detail.show; 
  if(!show){ // 子组件点击了关闭   关闭弹窗
    that.setData({
      show:false
    })
  }
  console.log("子组件：",e);
