本文例項為大家分享了uniapp實現橫向滾動選擇日期的具體程式碼，供大家參考，具體內容如下

1.方法封裝 common.js

//獲取當前時間，格式YYYY-MM-DD HH:MM:SS
const GetNowTime = time => {
 var date = time,year = date.getFullYear(),month = date.getMonth() + 1,day = date.getDate(),hour = date.getHours() < 10 ? "0" + date.getHours() : date.getHours(),minute = date.getMinutes() < 10 ? "0" + date.getMinutes() : date.getMinutes(),second = date.getSeconds() < 10 ? "0" + date.getSeconds() : date.getSeconds();
 month >= 1 && month <= 9 ? (month = "0" + month) : "";
 day >= 0 && day <= 9 ? (day = "0" + day) : "";
 // var timer = year + '-' + month + '-' + day + ' ' + hour + ':' + minute + ':' + second;
 var timer = year + '-' + month + '-' + day;
 return timer;
}

// 格式化電話號碼
const GetPhone = phone => {
 let tel = phone.slice(0,3) + '****' + phone.slice(7,11);
 return tel;
}
//返回日期和周幾陣列
function weekDate() {
 var myDate = new Date();
 myDate.toLocaleDateString();
 var month = myDate.getMonth() + 1;
 var time = myDate.getFullYear() + '年' + month + '月' + myDate.getDate() + '日';
 var total = 1; // 個數
 var dayList = [];
 dayList.push({
 'day': myDate.getDate(),'month': myDate.getMonth() + total,'week': toWeekDay(myDate.getDay()),'year': myDate.getFullYear()
 });
 for (var i = 0; i < 10; i++) {
 myDate.setDate(myDate.getDate() + total); // number 是最近幾天 則會自動計算
 // 需求 月份-日 星期幾  
 dayList.push({
 'day': myDate.getDate(),'year': myDate.getFullYear()
 })
 }
 // return dayList;
 let length = dayList.length
 let arrOne = dayList[0]
 let arrLast = dayList[length - 1]
 let StartDate = arrOne.year.toString() + '-' + arrOne.month + '-' + arrOne.day
 let EndDate = arrLast.year.toString() + '-' + arrLast.month + '-' + arrLast.day
 return {
 dayList,StartDate,EndDate
 }
}

function toWeekDay(weekDay) { // 傳入資料 講一週的某一天返回成中文狀態下的字元
 switch (weekDay) {
 case 1:
 return '一';
 break;
 case 2:
 return '二';
 break;
 case 3:
 return '三';
 break;
 case 4:
 return '四';
 break;
 case 5:
 return '五';
 break;
 case 6:
 return '六';
 break;
 case 0:
 return '日';
 break;
 default:
 break;
 }
 return '傳入未知引數';
}
module.exports = {
 GetNowTime,GetPhone,weekDate
}

2.元件.vue

<template>
 <view>
 <view class="box">
 <scroll-view scroll-x="true">
 <block v-for="(item,index) in dayList" :key="index">
  <view class="dayTitle" :class="current == index ? 'select' : ''" @click="timeSelectd(index)">
  <view style="display: flex;flex-direction: column;justify-content: center;width: 100%;height: 100%;">
  <view>{{ item.day }}</view>
  <view v-if="index == 0" style="font-size: 25upx;">今天</view>
  <view v-else style="font-size: 25upx;">星期{{ item.week }}</view>
  </view>
  </view>
 </block>
 </scroll-view>
 </view>
 </view>
</template>

<script>
import Vue from 'vue';
import common from '../../common/common.js';
export default {
 data() {
 return {
 isShow: false,current: 0,dayList: [],xzTime: common.GetNowTime(new Date())
 };
 },onLoad() {
 this.dayList = common.weekDate().dayList;
 },methods: {
 // 日期選擇
 timeSelectd(index) {
 this.current = index;
 let date = this.dayList[index].year + '-' + this.dayList[index].month + '-' + this.dayList[index].day;
 date = common.GetNowTime(new Date(date));
 this.xzTime = date;
 console.log(this.xzTime);
 }
 }
};
</script>

<style scoped>
.box {
 padding: 30upx;
}
scroll-view {
 padding: 20upx 0;
 width: 100%;
 white-space: nowrap;
}
.dayTitle {
 width: 120upx;
 height: 120upx;
 border-radius: 60upx;
 margin-left: 20upx;
 text-align: center;
 display: inline-block;
}
.select {
 color: #ffffff;
 background-color: #83cbac;
}
</style>
