1.方法封装 common.js

//获取当前时间，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;
}

// 格式化电话号码
const GetPhone = phone => {
 let tel = phone.slice(0, 3) + '****' + phone.slice(7, 11);
 return tel;
}
//返回日期和周几数组
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; // 个数
 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 是最近几天 则会自动计算
 // 需求 月份-日 星期几  
 dayList.push({
 'day': myDate.getDate(),
 'month': myDate.getMonth() + total,
 'week': toWeekDay(myDate.getDay()),
 '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) { // 传入数据 讲一周的某一天返回成中文状态下的字符
 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 '传入未知参数';
}
module.exports = {
 GetNowTime,
 GetPhone,
 weekDate
}

2.组件.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: {
 // 日期选择
 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>

以上是原作者的vue样式

下面是自己做了样式改动

<template>
    <view>
        <view class="box">
            <scroll-view scroll-x="true" class="scroll-box">
                <view class="dayTitle" :class="allDate ? 'select' : ''" @click="queryAll">
                    <view style="display: flex;flex-direction: column;justify-content: center;width: 100%;height: 100%;">
                        <view style="font-size: 25upx;">不限</view>
                        <view style="font-size: 25upx;">日期</view>
                    </view>
                </view>
                <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>

        },
        // onLoad:function(e) {

        methods: {

            timeSelectd(index) {

            date = common.GetNowTime(new Date(date));
            this.xzTime = date;
            console.log(this.xzTime);
            },
            queryAll(){
                this.allDate = !this.allDate
                this.current = -1
            }
        }
    };
</script>
