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：
javascript
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
html
<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
html
<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
html
<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：
javascript
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
javascript
initial() {
let minute = this.getMinute()
let hour = this.getHours()
if (hour < 9) {
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
javascript
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()
javascript
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
javascript
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
javascript
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
css
<style lang="scss" scoped>
.time-picker {

gap: 10px;
.timeBox {

background-color: #f7f8fa;
text-align: center;
}
.timeBox:hover {
color: red;
}
.active {
color: red;
background-color: #ffefef;
}
}
}
}

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
