vue3 element-plus el-date-picker日期组件再次封装(DatePicker与DateTimePicker合并根据type值来显示并自定义常规快捷方式)

2024-05-09 11:05:17 前端知识 前端哥 83 743 我要收藏

1、最终效果

在这里插入图片描述

2、TDatePicker 参数配置

1、简介:基于 ElementUI DatePicker DateTimePicker 组件的二次封装,取决于 type 值

代码示例:

<t-date-picker v-model="date" />

2、t-date-picker(Attributes)继承 DatePicker DateTimePicker 的 Attributes

参数说明类型默认值
v-model绑定值[String, Date, Array]-
plusTime日期范围是否显示 00:00:00 23:59:59 时分秒Booleanfalse
type时间类型(继承 element DatePicker DateTimePicker)Stringdate
shortcuts设置快捷选项,需要传入数组对象Array<{ text: string, value: Date & Function }>-
isPickerOptions是否开启自带快捷方式Booleanfalse

3、type 类型如下:

week 周;month 月;year 年;dates 多个日期;months 多个月;years 多个年;daterange 日期范围;monthrange 月份范围;datetime 日期和时间点;datetimerange 日期和时间点范围

4、events

事件名说明返回值
change用户确认选定的值时触发组件绑定值。格式与绑定值一致,可受 value-format 控制

Slots

事件名说明
default自定义内容
range-separator自定义范围分割符内容

3、源码
