vue2.0+elementui实现一个上门取件时间组件
作者:nihao561
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>
