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())
};
},
onl oad() {
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>
</view>
</block>
</scroll-view>
</view>
</view>
</template>
<script>
import Vue from 'vue';
import common from './js/formatDate.js';
export default {
props:{
dayList: {
type: Object,
default: function() {
return {}
}
},
},
data() {
return {
isShow: false,
current: 0,
allDate:false,
// dayList: [],
xzTime: common.GetNowTime(new Date())
};
},
// onl oad:function(e) {
// 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);
},
queryAll(){
this.allDate = !this.allDate
this.current = -1
}
}
};
</script>
<style scoped>
.box {
padding: 30upx;
}
.scroll-box {
padding: 20upx 0;
width: 100%;
white-space: nowrap;
}
.dayTitle {
width: 80upx;
height: 80upx;
/* border-radius: 60upx; */
margin-left: 20upx;
text-align: center;
display: inline-block;
}
.select {
color: #80d1c2;
/* background-color: #83cbac; */
}
</style>
