1.界面代码

<view class="o-calendar"><view class="o-calendar-container" ><view class="o-calendar-titlebar"><view class="o-left_arrow" bind:tap="prevMonth">《</view>{{year}}年{{month}}月<view class="o-right_arrow" bind:tap="nextMonth">》</view><view class="o-btn-current-month" bind:tap="locateThisMonth"><image class="o-btn-current-month-img" src="../../images/month.svg" /></view></view><view class="o-calendar-weekdays"><view wx:for="{{weekdays}}" wx:key="id" class="o-calendar-weekdays-item" >{{item}}</view></view><view class="o-calendar-weeks"><block wx:for="{{calendarData}}" wx:key="index" ><view class="o-calendar-week"><block wx:for="{{item}}" wx:key="index"><block wx:if="{{item===0}}"><view class="o-calendar-item"></view></block><block wx:else><block wx:if="{{today && item===day}}"><view class="o-calendar-day o-calendar-day-cur" bindtap="selectDate" data-value='{{item}}'>{{item}}</view></block><block wx:elif="{{item===selectedDay}}"><view class="o-calendar-day o-calendar-day-selected" bindtap="selectDate" data-value='{{item}}'>{{item}}</view></block><block wx:else><view class="o-calendar-day" bindtap="selectDate" data-value='{{item}}'>{{item}}</view></block></block> </block></view></block></view></view> </view>

2.样式设置

page{--o-calendar-background-color: #F1EBFE;
}.o-calendar {width: 100%;display: flex;flex-direction: column;box-sizing: border-box;padding: 10rpx 30rpx;
} .o-calendar-container{padding: 0rpx 16rpx;background-color: var(--o-calendar-background-color);border-radius: 20rpx;
}.o-calendar-titlebar{display: flex;justify-content: center;align-items: center;height: 50rpx;font-size: 18px;font-weight: bold;padding-top: 20rpx;
}.o-left_arrow {width: 50rpx;height: 50rpx;position: absolute;left: 180rpx;
}.o-right_arrow {width: 50rpx;height: 50rpx;position: absolute;right: 180rpx;
}.o-btn-current-month{width: 50rpx;height: 50rpx;position: absolute;right: 80rpx;
}
.o-btn-current-month-img{width: 100%;height: 100%;
}.o-calendar-weekdays{width: 100%;height: 80rpx;display: flex;justify-content: space-between;align-items: center;
}
.o-calendar-weekdays-item{width: 60rpx;line-height: 60rpx;text-align: center;margin: 5rpx;
}.o-calendar-week{width: 100%;display: flex;justify-content: space-between;
}.o-calendar-item{width: 60rpx;height: 60rpx;position: relative;line-height: 60rpx;margin: 5rpx;
}.o-calendar-day {width: 60rpx;height: 60rpx;position: relative;display: flex;line-height: 60rpx;text-align: center;justify-content: center;margin: 5rpx;border-radius: 50%;cursor: pointer;background-color: #fff;
}.o-calendar-day-cur{font-weight: bold;color: #fff;background-color: #F6AD77;
}.o-calendar-day-selected{font-weight: bold;color: #fff;background-color: rgb(7, 3, 1);
}

3.typescript脚本处理

  /*** 页面的初始数据*/data: {year: 0, //记录年month: 0, //记录月day:0,//记录日selectedDay:0,calendarData: [], //记录日期weekdays: ['日', '一', '二', '三', '四', '五', '六'],today:false,},/*** 生命周期函数--监听页面加载*/onLoad() {this.renderCalendar();},renderCalendar: function () {//获取当前日期const currentDate:Date = new Date();const currentYear:number = currentDate.getFullYear();const currentMonth:number = currentDate.getMonth() + 1;const currentDay:number = currentDate.getDate();//获取年月日，未设置时默认当前日期const year:number = this.data.year || currentYear;const month:number = this.data.month || currentMonth;const day:number = this.data.day || currentDay;// 获取指定月份的总天数const totalDays:number = new Date(year, month, 0).getDate();// 获取指定月份第一天是星期几let firstDayOfWeek:number = new Date(year, month - 1, 1).getDay();//构建周期偏移实际数据let total = firstDayOfWeek + totalDays;// Math.ceil(total/7) -> 实际周期数total = Math.ceil(total/7)*7;// 定义存放日历数据的数组const calendarData:number[][] = [];// 初始化一个星期的数组let week:number[] = [];let num:number =0;for(let i=1;i<=total;i+=7){week = [];for(let j=0;j<7;j++){num = i-firstDayOfWeek +jweek.push(num<0 || num>totalDays? 0: num)}calendarData.push(week);}// 将生成的日历数据更新到页面数据中，使页面重新渲染this.setData({year: year,month: month,day:day,calendarData: calendarData as any,selectedDay:this.data.selectedDay,today: year==currentYear && month==currentMonth && day==currentDay,});
},selectDate(event: any){//console.log(event);this.setData({selectedDay: event.currentTarget.dataset.value,});},prevMonth(event: any){this.data.month -= 1;if(this.data.month==0){this.data.year -= 1;this.data.month = 12;}this.data.selectedDay=0;this.renderCalendar();},nextMonth(event: any){this.data.month += 1;if(this.data.month==13){this.data.year += 1;this.data.month = 1;}this.data.selectedDay=0;this.renderCalendar();},locateThisMonth(event: any){this.data.year=0;this.data.month=0;this.data.day=0;this.data.selectedDay=0;this.renderCalendar();},
