## DatePicker 日期选择器
|
||
|
||
用于选择或输入日期
|
||
|
||
### 选择日
|
||
|
||
以「日」为基本单位，基础的日期选择控件
|
||
|
||
:::demo 基本单位由`type`属性指定。快捷选项需配置`picker-options`对象中的`shortcuts`，禁用日期通过 `disabledDate` 设置，传入函数
|
||
```html
|
||
<template>
|
||
<div class="block">
|
||
<span class="demonstration">默认</span>
|
||
<el-date-picker
|
||
v-model="value1"
|
||
type="date"
|
||
placeholder="选择日期"
|
||
:picker-options="pickerOptions0">
|
||
</el-date-picker>
|
||
</div>
|
||
<div class="block">
|
||
<span class="demonstration">带快捷选项</span>
|
||
<el-date-picker
|
||
v-model="value2"
|
||
align="right"
|
||
type="date"
|
||
placeholder="选择日期"
|
||
:picker-options="pickerOptions1">
|
||
</el-date-picker>
|
||
</div>
|
||
</template>
|
||
|
||
<script>
|
||
export default {
|
||
data() {
|
||
return {
|
||
pickerOptions0: {
|
||
disabledDate(time) {
|
||
return time.getTime() < Date.now() - 8.64e7;
|
||
}
|
||
},
|
||
pickerOptions1: {
|
||
shortcuts: [{
|
||
text: '今天',
|
||
onClick(picker) {
|
||
picker.$emit('pick', new Date());
|
||
}
|
||
}, {
|
||
text: '昨天',
|
||
onClick(picker) {
|
||
const date = new Date();
|
||
date.setTime(date.getTime() - 3600 * 1000 * 24);
|
||
picker.$emit('pick', date);
|
||
}
|
||
}, {
|
||
text: '一周前',
|
||
onClick(picker) {
|
||
const date = new Date();
|
||
date.setTime(date.getTime() - 3600 * 1000 * 24 * 7);
|
||
picker.$emit('pick', date);
|
||
}

value1: '',
