<!-- 日期时间选择器组件 带日周月快捷选项
|
会将初始默认时间（一周前）和改变的时间通过事件‘submitTime’传递给父组件
|
|
初始渲染时就将时间传递给父组件：
|
**
|
在父组件中设置
|
<TimeSelectWithShortCuts @submit-time="giveTime"></TimeSelectWithShortCuts>
|
giveTime(val) {
|
//将中国标准时间转为指定格式(该组件返回的标准时间的格式，所以必须的加这个函数)
|
this.beginTime = dayjs(val[0]).format('YYYY-MM-DD HH:mm:ss');
|
this.endTime = dayjs(val[1]).format('YYYY-MM-DD HH:mm:ss');
|
},
