vue3+ts 基于内置组件picker-view + 扩展组件 Popup 实现自定义日期选择及其他选择

自我记录

1.先上效果图

直接上代码

2.代码展示

2.1 组件

src\components\HbcyPopup.vue

<script setup lang="ts">
import { formatDate, parseDate } from '@/utils'
import { ref } from 'vue'const props = defineProps<{popupTitle: stringtype: 'year' | 'month' | 'day'defaultDate: string
}>()
const emit = defineEmits<{(e: 'confirm-popup', params: string): void(e: 'close-popup'): void
}>()// 选中的值
const selectDate = ref('')
// 创建选择区间 参考uni文档
const date = new Date()
// 年月日
const TYPEYY_MM_DD = props.type === 'year' || props.type === 'month' || props.type === 'day'
// 月日
const TYPEMM_DD = props.type === 'month' || props.type === 'day'
const TYPEYY = props.type === 'year'
const TYPEMM = props.type === 'month'
const TYPEDD = props.type === 'day'
const years = TYPEYY_MM_DD? Array.from({ length: date.getFullYear() - 1989 }, (_, index) => 1990 + index): []
const months = TYPEMM_DD ? Array.from({ length: 12 }, (_, index) => index + 1) : []
const days = TYPEDD ? Array.from({ length: 31 }, (_, index) => index + 1) : []
// 处理默认展示的时间
const defaultDate = parseDate(props.defaultDate, props.type)
// 确保默认时间
const year = ref<number>(defaultDate[0])
const month = ref<number | undefined>(defaultDate[1])
const day = ref<number | undefined>(defaultDate[2])
// 区分日期展示
let showValueList: any = []
// 展示日期的选中时间
if (TYPEDD) {showValueList = [years.indexOf(defaultDate[0]),months.indexOf(defaultDate[1]!),days.indexOf(defaultDate[2]!),]
} else if (TYPEMM) {showValueList = [years.indexOf(defaultDate[0]), months.indexOf(defaultDate[1]!)]
} else if (TYPEYY) {showValueList = [years.indexOf(defaultDate[0])]
}
const valueList = ref<number[]>(showValueList)// 切换日期
const bindChange: UniHelper.PickerViewOnChange = (e) => {const val = e.detail.valueyear.value = years[val[0]]month.value = months[val[1]]day.value = days[val[2]]
}
// 确定按钮
const onClickConfirmPopup = (): void => {selectDate.value = formatDate(year.value, month.value, day.value)emit('confirm-popup', selectDate.value)onClosePopup()
}
// 关闭弹出层
const onClosePopup = (): void => {emit('close-popup')
}
const { safeAreaInsets } = uni.getSystemInfoSync()
</script><template><view class="selectBox"><view class="selectTitle"><text class="cancel" @click="onClosePopup">取消</text><text class="title">{{ '选择' + popupTitle }}</text><text class="cancel ok" @click="onClickConfirmPopup">确定</text></view><block v-if="TYPEYY_MM_DD"><picker-view:immediate-change="true"indicator-class="indicatorClass":value="valueList"@change="bindChange"class="picker-view"><picker-view-column><view class="item" v-for="(item, index) in years" :key="index">{{ item }}年</view></picker-view-column><picker-view-column v-if="TYPEMM_DD"><view class="item" v-for="(item, index) in months" :key="index">{{ item }}月</view></picker-view-column><picker-view-column v-if="TYPEDD"><view class="item" v-for="(item, index) in days" :key="index">{{ item }}日</view></picker-view-column></picker-view></block><!-- TODO --><block v-else> <text>我是单列</text> </block><!-- 修复启用:safeArea="true" 时 圆角不好实现问题,现在是自己做的适配--><view :style="{ height: safeAreaInsets?.bottom + 'px' }" style="width: 100%" /></view>
</template><style lang="scss" scoped>
::v-deep.indicatorClass {height: 100rpx;
}
.picker-view {width: 750rpx;height: 500rpx;margin-top: 20rpx;
}
.item {line-height: 100rpx;text-align: center;
}
.selectBox {width: 100%;height: fit-content;background-color: #fff;border-radius: 20rpx 20rpx 0 0;.selectTitle {display: flex;justify-content: space-between;align-items: center;height: 100rpx;font-size: 32rpx;.title {font-size: 32rpx;}.cancel {width: 160rpx;text-align: center;color: #ff976a;font-size: 32rpx;}.ok {font-size: 32rpx;color: #07c160;}}
}
</style>

2.2 公共方法处理日期

src\utils\index.ts

// 将 yyyy-mm-dd 的字符串 2023-08-24 => [2023,8,24] || [2023,8] || [2023]
export function parseDate(dateString: string, type: string): [number, number?, number?] {const date = dateString ? new Date(dateString) : new Date()const year = date.getFullYear()const month = type === 'day' || type === 'month' ? date.getMonth() + 1 : undefinedconst day = type === 'day' ? date.getDate() : undefinedreturn [year, month, day]
}// 将数字格式的年、月、日转换成格式为 yyyy-mm-dd 的字符串 || yyyy-mm || yyyy
export function formatDate(year: number, month?: number, day?: number): string {const formattedMonth = month !== undefined ? (month < 10 ? `0${month}` : `${month}`) : ''const formattedDay = day !== undefined ? (day < 10 ? `0${day}` : `${day}`) : ''return `${year}${formattedMonth ? `-${formattedMonth}` : ''}${formattedDay ? `-${formattedDay}` : ''}`
}

2.3 使用组件

src\pages\test\index.vue

<script setup lang="ts">
import type { Ref } from 'vue'
import { ref } from 'vue'// 日期相关
const isShowPopop = ref(false)
// 弹出层实例
const refSelectDialog: Ref<UniHelper.UniPopup | null> = ref(null)
const dateTime = ref('')
// 打开日期弹窗
const onClcikPopup = () => {refSelectDialog.value!.open()isShowPopop.value = trueconsole.log(refSelectDialog, 'refPopup')
}
// 关闭弹窗
const onClosePopup = () => {refSelectDialog.value!.close()isShowPopop.value = false
}
// 确定日期弹窗
const onConfirmPopup = (params: string) => {dateTime.value = paramsconsole.log(dateTime.value, 'dateTime.value')
}
</script><template><view class="test-page"><!-- 展示信息 --><view @tap="onClcikPopup" class="item-date"><text class="item-date-placeholder" v-show="!dateTime">请选择时间</text><text class="item-date-txt" v-show="dateTime">{{ dateTime }}</text></view><!-- 使用组件 --><uni-popupref="refSelectDialog"type="bottom":maskClick="false":isMaskClick="false":safeArea="false":close="onClosePopup"><HbcyPopupv-if="isShowPopop"popupTitle="日期"type="day":defaultDate="dateTime"@confirm-popup="onConfirmPopup"@close-popup="onClosePopup"/></uni-popup></view>
</template><style lang="scss" scoped>
.test-page {.item-date {width: 300rpx;height: 60rpx;line-height: 60rpx;text-align: center;border: 1rpx solid #999;font-size: 28rpx;&-placeholder {color: #999;}&-txt {color: #333;}}
}
</style>

3.注意事项

3.1refSelectDialog

// 弹出层实例
const refSelectDialog: Ref<UniHelper.UniPopup | null> = ref(null)

• ts类型有一些问题,找了好久不知道该给什么类型!!! 新手TS,有大佬的话请指出,感谢!

3.1 backgroundColor="#fff" 圆角问题

<uni-popup backgroundColor="#fff" /> 

• 因为默认是开启适配的,需要加上背景色,否则就是透明的底部区域
• 示例如下:
