uni-app日期范围选择，颗粒度为年-月-日

本文主要是介绍uni-app日期范围选择，颗粒度为年-月-日，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

效果图：

 

1.在components中引入term-picker.vue

<template><view :class="{'pickerMask':visable}" @click="maskClick" @touchmove.stop.prevent="returnHandle"><view class="picker-box" :class="{'picker-show':visable}"><view class="operate-box" @touchmove.stop.prevent="returnHandle" @tap.stop="returnHandle"><view class="time-box"><view @click="touchSelect(0)" class="time-item" :style="{color:touchIndex?'#000000':themeColor}"><text>{{startText}}</text><text>{{resultDate[0]}}</text></view><text>至</text><view @click="touchSelect(1)" class="time-item" :style="{color:touchIndex?themeColor:'#000000'}"><text>{{endText}}</text><text>{{resultDate[1]}}</text></view></view><view :style="{color:themeColor}" @click="pickerConfirm">确定</view></view><picker-view :value="pickerValue" @change="pickerChange" class="picker-view" :indicator-style="indicatorStyle" @tap.stop="returnHandle"><picker-view-column><view class="picker-item" v-for="(item, index) in years" :key="index">{{item}}年</view></picker-view-column><picker-view-column><view class="picker-item" v-for="(item, index) in months" :key="index">{{ item }}月</view></picker-view-column><picker-view-column v-if="days.length > 0"><view class="picker-item" v-for="(item, index) in days" :key="index">{{ item }}日</view></picker-view-column></picker-view></view></view>
</template>
<script>export default {name: 'termPicker',props: {visable: {type: Boolean,default: false},defaultDate: {type: Array,default: () => []},minYear: {type: Number,default: 1990,},themeColor:{type: String,default: '#10BE9D'},startText: {type: String,default: '开始时间'},endText: {type: String,default: '结束时间'}},data() {const date = new Date();const years = [];const year = date.getFullYear();const months = [];const month = date.getMonth() + 1;const day = date.getDate();for (let i = this.minYear; i <= date.getFullYear(); i++) {years.push(i);}for (let i = 1; i <= 12; i++) {months.push(i);}return {indicatorStyle: 'height: 100rpx;',touchIndex: 0,year,month,day,years,months,days: [],pickerValue: [],resultDate: []};},mounted() {this.setDate()},methods: {returnHandle(){},setDate() {if (this.defaultDate.length > 0) {let date = this.defaultDate[0]this.resultDate = this.defaultDatethis.setPicker(date)} else {let month = this.month < 10 ? '0' + this.month : this.monthlet day = this.day < 10 ? '0' + this.day : this.daylet nowTime = this.year + '-' + month + '-' + daythis.resultDate = [nowTime, nowTime]this.setPicker(nowTime)}},setPicker(date) {const splitVal = date.split('-')let year = this.years.indexOf(Number(splitVal[0]))let month = Number(splitVal[1]) - 1let day = Number(splitVal[2]) - 1this.pickerChange({detail: {value: [year, month, day]}})},touchSelect(val) {let date = this.resultDate[val]this.touchIndex = valthis.setPicker(date)},getDateTime(date) {let year = this.years[date[0]]let month = this.months[date[1]]let day = this.days[date[2]]if (month < 10) {month = '0' + month}if (day < 10) {day = '0' + day}this.resultDate[this.touchIndex] =  year + '-' + month + '-' + day},pickerChange(e) {const currents = e.detail.value;if (currents[1] + 1 === 2) {this.days = [];if (((currents[0] + this.minYear) % 4 === 0 &&(currents[0] + this.minYear) % 100 !== 0) ||(currents[0] + this.minYear) % 400 === 0) {for (let i = 1; i < 30; i++) {this.days.push(i);}} else {for (let i = 1; i < 29; i++) {this.days.push(i);}}} else if ([4, 6, 9, 11].some((item) => currents[1] + 1 === item)) {this.days = [];for (let i = 1; i < 31; i++) {this.days.push(i);}} else if ([1, 3, 5, 7, 8, 10, 12].some((item) => currents[1] + 1 === item)) {this.days = [];for (let i = 1; i < 32; i++) {this.days.push(i);}}this.pickerValue = currentsthis.getDateTime(currents)},maskClick() {this.$emit('update:visable', false)},pickerConfirm() {const { resultDate } = thislet startTime = new Date(resultDate[0]).getTime()let endTime = new Date(resultDate[1]).getTime()let nowTime = new Date().getTime()if (startTime <= endTime && endTime <= nowTime) {this.$emit('confirm', resultDate)this.maskClick()} else {uni.showToast({title: '时间范围不正确！',icon: 'none'})}}}}
</script><style lang="scss" scoped>.pickerMask {position: fixed;z-index: 998;top: 0;right: 0;left: 0;bottom: 0;background: rgba(0, 0, 0, 0.6);}.picker-box {position: fixed;bottom: 0;left: 0;width: 100%;transition: all 0.3s ease;transform: translateY(100%);z-index: 998;.operate-box {display: flex;align-items: center;justify-content: space-between;padding: 18rpx 30rpx;background-color: #FFFFFF;text-align: center;font-size: 30rpx;border-bottom: 2rpx solid #e5e5e5;.time-box {width: 60%;display: flex;align-items: center;justify-content: space-between;.time-item {display: flex;flex-direction: column;}}}}.picker-show {transform: translateY(0);}.picker-view {width: 750rpx;height: 600rpx;background-color: #FFFFFF;.picker-item {height: 100rpx;display: flex;align-items: center;justify-content: center;text-align: center;}}
</style>

2.使用

<template><view class="content"><view class="header"><view class="date-item">年月范围：{{startDay}} - {{endDay}}</view></view><button class="date-btn" type="default" @click="openPicker">打开</button>
<term-picker :visable.sync="pickerShowByDay" :defaultDate="defaultDay" :maxDay="maxDay" @confirm="confirmByDay">
</term-picker></view>
</template><script>import termPicker from '/components/term-picker/term-picker.vue'; //日期选择export default {components: {termPicker},data() {return {pickerShowByDay: false, //是否日期选择控件defaultDay: [], //日期默认选择，为空则是当前日期maxDay: 60, //最大跨度日startDay: '',endDay: ''}},methods: {openPicker() {this.pickerVisable = true},confirm(date) {this.startDay = date[0]this. endDay = date[1]}}}
</script><style>.header {width: 100%;padding: 60rpx 30rpx;display: flex;flex-direction: column;}.date-item {margin-bottom: 30rpx;}.date-btn {width: 500rpx;height: 80rpx;line-height: 80rpx;}
</style>
