1. 创建日历组件实现步骤：

1. 创建日历组件：首先，你需要创建一个日历组件，包含显示日期的逻辑。
2. 样式设计：为日历组件设计样式，使其看起来美观。
3. 事件处理：添加事件处理程序，以便用户可以选择日期。

2. 代码实现过程

1. 编写calendar.wxml布局

<!-- calendar.wxml -->
<navigation-bar title="日历控件" back="{{false}}" color="#FFFFFF" background="#e6142c"></navigation-bar><!-- 日历部分 --><view class="calendar"><!-- 日历头部 --><view class="calendar-header"><view class="arrow" bindtap="prevMonth">〈</view><view class="date-title">{{year}}年{{month}}月</view><view class="arrow" bindtap="nextMonth">〉</view></view><!-- 星期标题 --><view class="weekday-row"><view class="weekday" wx:for="{{weekdays}}" wx:key="*this">{{item}}</view></view><!-- 日期格子 --><view class="date-rows"><view class="date-row" wx:for="{{dateList}}" wx:for-item="row" wx:key="index"><view class="date-cell {{item.currentMonth ? '' : 'other-month'}} {{item.isToday ? 'today' : ''}} {{item.selected ? 'selected' : ''}}" wx:for="{{row}}" wx:key="date" bindtap="selectDate" data-date="{{item.date}}">{{item.day}}</view></view></view></view>

2. 编写calendar.wxss样式

/* calendar.wxss */
page {height: 100vh;display: flex;flex-direction: column;background-color: #f5f5f5;
}.calendar {background: #f5f5f5;border-radius: 10rpx;padding: 20rpx;
}.calendar-header {display: flex;align-items: center;justify-content: space-between;padding: 20rpx 0;
}.date-title {font-size: 32rpx;font-weight: bold;
}.arrow {padding: 10rpx 20rpx;color: #666;
}.weekday-row {display: flex;border-bottom: 1rpx solid #eee;padding-bottom: 10rpx;margin-bottom: 10rpx;
}.weekday {flex: 1;text-align: center;font-size: 28rpx;color: #666;
}.date-rows {display: flex;flex-direction: column;
}.date-row {display: flex;margin: 5rpx 0;
}.date-cell {flex: 1;text-align: center;padding: 15rpx 0;font-size: 28rpx;position: relative;height: 65rpx;line-height: 65rpx;margin: 5rpx;
}.selected {background: #e6142c;color: #fff !important;/* 确保选中时文字颜色为白色 */border-radius: 50%;
}/* 确保今天的样式和选中样式可以共存 */
.today {color: #e6142c;font-weight: bold;
}.today.selected {color: #fff !important;background: #e6142c;
}/* 其他月份日期的样式 */
.other-month {color: #ccc;
}.other-month.selected {background: #1aad19;color: #fff !important;
}

3. 编写calendar.js具体逻辑实现

// calendar.js
Page({data: {year: 2024,month: 1,day: 1,weekdays: ['日', '一', '二', '三', '四', '五', '六'],dateList: [],selectedDate: null,dateStr: '',},onLoad() {// 初始化当前日期const now = new Date()this.setData({year: now.getFullYear(),month: now.getMonth() + 1,selectedDate: now // 设置当前日期为选中状态}, () => {this.generateDateList()})wx.showToast({title: this.data.selectedDate.toLocaleDateString(),icon:"none"})},// 生成日历数据generateDateList() {const {year,month} = this.dataconst dateList = []// 获取当月第一天和最后一天const firstDay = new Date(year, month - 1, 1)const lastDay = new Date(year, month, 0)// 获取当月第一天是星期几const firstDayWeek = firstDay.getDay()// 获取上个月的最后几天const prevMonthLastDay = new Date(year, month - 1, 0).getDate()// 当前日期const today = new Date()const currentDateStr = today.toDateString()// 填充上个月的日期let row = []for (let i = 0; i < firstDayWeek; i++) {const day = prevMonthLastDay - firstDayWeek + i + 1const date = new Date(year, month - 2, day)row.push({day,date: date,currentMonth: false,isToday: date.toDateString() === currentDateStr,selected: this.data.selectedDate && date.toDateString() === this.data.selectedDate.toDateString()})}// 填充当月日期for (let day = 1; day <= lastDay.getDate(); day++) {const date = new Date(year, month - 1, day)row.push({day,date: date,currentMonth: true,isToday: date.toDateString() === currentDateStr,selected: this.data.selectedDate && date.toDateString() === this.data.selectedDate.toDateString()})if (row.length === 7) {dateList.push(row)row = []}}// 填充下个月的日期let nextMonthDay = 1while (row.length < 7) {const date = new Date(year, month, nextMonthDay)row.push({day: nextMonthDay++,date: date,currentMonth: false,isToday: date.toDateString() === currentDateStr,selected: this.data.selectedDate && date.toDateString() === this.data.selectedDate.toDateString()})}dateList.push(row)this.setData({dateList})},// 选择日期selectDate(e) {const selectedDate = new Date(e.currentTarget.dataset.date)this.setData({selectedDate: selectedDate}, () => {this.generateDateList()//格式化日期const date = new Date(selectedDate.toLocaleDateString())wx.showToast({title: selectedDate.toLocaleDateString(),icon:"none"})})},// 生成日历数据generateDateList() {const {year,month} = this.dataconst dateList = []// 获取当月第一天和最后一天const firstDay = new Date(year, month - 1, 1)const lastDay = new Date(year, month, 0)// 获取当月第一天是星期几const firstDayWeek = firstDay.getDay()// 获取上个月的最后几天const prevMonthLastDay = new Date(year, month - 1, 0).getDate()// 当前日期const today = new Date()const currentDateStr = today.toDateString()// 选中的日期字符串（用于比较）const selectedDateStr = this.data.selectedDate ? this.data.selectedDate.toDateString() : ''// 填充上个月的日期let row = []for (let i = 0; i < firstDayWeek; i++) {const day = prevMonthLastDay - firstDayWeek + i + 1const date = new Date(year, month - 2, day)const dateStr = date.toDateString()row.push({day,date: dateStr,currentMonth: false,isToday: dateStr === currentDateStr,selected: selectedDateStr && dateStr === selectedDateStr})}// 填充当月日期for (let day = 1; day <= lastDay.getDate(); day++) {const date = new Date(year, month - 1, day)const dateStr = date.toDateString()row.push({day,date: dateStr,currentMonth: true,isToday: dateStr === currentDateStr,selected: selectedDateStr && dateStr === selectedDateStr})if (row.length === 7) {dateList.push(row)row = []}}// 填充下个月的日期let nextMonthDay = 1while (row.length < 7) {const date = new Date(year, month, nextMonthDay)const dateStr = date.toDateString()row.push({day: nextMonthDay++,date: dateStr,currentMonth: false,isToday: dateStr === currentDateStr,selected: selectedDateStr && dateStr === selectedDateStr})}if (row.length > 0) {dateList.push(row)}this.setData({dateList})},// 上个月prevMonth() {let {year,month} = this.dataif (month === 1) {year--month = 12} else {month--}this.setData({year,month}, () => {this.generateDateList()})},// 下个月nextMonth() {let {year,month} = this.dataif (month === 12) {year++month = 1} else {month++}this.setData({year,month}, () => {this.generateDateList()})}});
