上面是components中封装的时间选择器组件

下面是使用方法

<div><dateTimePickerSelect:startTime.sync="queryParams.ticketPrintTimeBegin":endTime.sync="queryParams.ticketPrintTimeEnd"></dateTimePickerSelect>
</div>
<script>
import dateTimePickerSelect from "@/components/dateTimePickerSelect";
export default {components:{dateTimePickerSelect,}
}
</script>
