本文实例为大家分享了小程序日历展示的具体代码,供大家参考,具体内容如下

根据前面的日历,又遇到到个好玩的日历需求,分享给大家

 小程序实现带年月选取效果的日历

这是个带年月左右选取的日历展示!并且当天的对应日会被高亮显示!下面看下实现代码!

1.wxml代码结构

<view class='wrap'> 
  <view> 
    <view class='date-show'> 
      <view class='lt-arrow' bindtap='lastMonth'> 
        <image src='../images/nextMonth.png' mode='aspectFit'></image> 
      </view> 
      {{year}}年{{month}}月 
      <view class='rt-arrow' bindtap='nextMonth'> 
        <image src='../images/nextMonth.png' mode='aspectFit'></image> 
      </view> 
    </view> 
  </view> 
  <view class='header'> 
    <view wx:for='{{date}}' class='{{(index == todayIndex) && isTodayWeek "weekMark" : ""}}'>{{item}}<view></view></view> 
  </view> 
  <view class='date-box'> 
    <view wx:for='{{dateArr}}' class='{{isToday == item.isToday "nowDay" : ""}}' data-date='{{item.isToday}}'>      
      <view class='date-head'> 
        <view>{{item.dateNum}}</view> 
      </view> 
      <view class='date-weight'>{{item.weight}}</view> 
    </view> 
  </view> 
</view>
