本文使用vue2.0+elementui 制作一个上门取件时间组件,类似顺丰,样式如下:
大概功能:点击期望上门时间,下面出现一个弹框可以选择时间:
首先我们定义一些需要的数据:
data() {
return {
isDropdown: false,
dayList: [],
listArray: [
"08:00~09:00",
"09:00~10:00",
"10:00~11:00",
"11:00~12:00",
"12:00~13:00",
"13:00~14:00",
"14:00~15:00",
"15:00~16:00",
"16:00~17:00",
"17:00~18:00",
"18:00~19:00",
"19:00~19:30",
],
timeToList: {
},
timeValue: "今天",
clickValue: "一小时内",
clickDay: "今天",
time: "",
}
},
接着我们画一个期望上门时间的长框,点击可以出现弹窗,点击外部弹窗消失,这中间我们使用了import Clickoutside from ‘element-ui/src/utils/clickoutside’ 这一组件,来帮助我们达到这个目的
<template>
<div class="time-picker" @click="openDown" v-clickoutside="clickoutside">
<div class="content-first">
<div class="redSpan">*</div>
<div>期望上门时间</div>
</div>
<div class="content-first">
<div>
{{ time }}
</div>
<i class="el-icon-s-order"></i>
</div>
</template>
接下来画一个弹出页面,弹出页面顶部是一个tab组件,这里通过daylist循环获得
<div class="time">
<div v-for="item in dayList" class="item" :class="timeValue == item.lable ? 'active' : ''"
@click="dayChange(item)">
<div>{{ item.lable }}</div>
<div>{{ item.ymd }}</div>
</div>
</div>
tab组件中的内容,是下单时间的按钮集合,通过timeToList 这个结构体 ,先获取数组再循环生成
<div class="timeList">
<div v-for="item in timeToList[timeValue]" @click="timeChange(item)" class="timeBox"
:class="clickDay == item.day && clickValue == item.lable ? 'active' : ''">
{{ item.lable }}
</div>
</div>
页面写好了我们开始写逻辑代码,先需要一些工具函数获取小时、分钟、年月日,一个用来判定点击了哪个按钮的list(由于是双层结构tab+button集,所以需要两个值来判定),一个获取今天按钮列表的函数:
getHours() {
const now = new Date();
return now.getHours();
},
getMinute() {
const now = new Date();
return now.getMinutes();
},
formatDate(date) {
const year = date.getFullYear();
const month = String(date.getMonth() + 1).padStart(2, '0');
const day = String(date.getDate()).padStart(2, '0');
return `${year}-${month}-${day}`;
},
transTime(arr, day) {
let temp = []
arr.forEach((item) => {
temp.push({
lable: item,
day: day
})
})
return temp
},
getTodayList(arr) {
let minute = this.getMinute()
let hour = this.getHours()
if (hour < 8)
return arr
if (hour >= 19 && minute > 30)
return []
arr = arr.slice(hour - 7)
arr = ['一小时内', ...arr]
return arr
}
然后我们需要先初始化数据
initial() {
let minute = this.getMinute()
let hour = this.getHours()
if (hour < 8) {
this.clickValue = "08:00~09:00"
this.clickDay = "今天"
return
}
if (hour >= 19 && minute > 30) {
this.clickValue = "08:00~09:00"
this.clickDay = "明天"
return
}
},
然后将时间赋值,这里其实可以用computed,但是我还是习惯自己做这部分操作
setTime() {
this.time = this.clickDay + ' ' + this.clickValue
},
接下来我们需要生成tab表单dayList,以及每个tab页面下面的时间选项,用了上面的两个工具函数getTodayList(),transTime()
getDay() {
const today = new Date()
const tomorrow = new Date(today)
tomorrow.setDate(tomorrow.getDate() + 1)
const afterTomorrow = new Date(today)
afterTomorrow.setDate(afterTomorrow.getDate() + 2)
let dayArray = [this.formatDate(today), this.formatDate(tomorrow), this.formatDate(afterTomorrow)]
let dayName = ['今天', '明天', '后天']
this.dayList = dayName.map((item, index) => {
return {
lable: item,
ymd: dayArray[index]
}
})
},
getTimeToList() {
this.dayList.forEach((item) => {
let arr = JSON.parse(JSON.stringify(this.listArray))
if (item.lable === "今天")
arr = this.getTodayList(arr)
this.timeToList[item.lable] = this.transTime(arr, item.lable)
})
},
通过上面的初始化函数,可以生成下拉页面的组件内容,函数顺序如下
mounted() {
this.initial()
this.setTime()
this.getDay()
this.getTimeToList()
},
最后我们添加一些点击动作,完整代码
openDown() {//打开下来框
this.isDropdown = true
},
clickoutside(e) {//关闭下拉框
if (!e) {
this.isDropdown = false
this.timeValue = this.clickDay
}
},
dayChange(item) {//切换tab页面
this.timeValue = item.lable
},
timeChange(item) {//选择下单时间
this.clickValue = item.lable
this.clickDay = item.day
this.setTime()
},
贴一下css代码
<style lang="scss" scoped>
.time-picker {
background-color: #f4f5f7;
width: 336px;
height: 32px;
padding: 0 6px;
display: flex;
justify-content: space-between;
cursor: pointer;
.content-first {
display: flex;
align-items: center;
gap: 3px;
.redSpan {
color: red;
}
}
.dropdown {
position: absolute;
top: 32px;
right: 0px;
z-index: 99;
width: 100%;
height: 220px;
background-color: #fff;
box-shadow: 0 8px 12px 0 rgba(0, 0, 0, 0.04);
border-radius: 10px;
padding: 6px;
.time {
display: flex;
.item {
width: 33%;
height: 45px;
text-align: center;
font-size: 14px;
line-height: 18px;
border-bottom: 1px solid #cccccc;
}
.active {
color: red;
border-bottom: 1px solid red;
}
}
.timeList {
padding: 10px;
display: flex;
align-items: center;
flex-wrap: wrap;
gap: 10px;
.timeBox {
width: 93px;
height: 29px;
background-color: #f7f8fa;
text-align: center;
}
.timeBox:hover {
color: red;
}
.active {
color: red;
background-color: #ffefef;
}
}
}
}
</style>

有需要的自取,麻烦给git一个星星!!!
以后要开始好好搞github自己的个人项目了
