这篇文章主要为大家详细介绍了微信小程序日历组件的使用方法,具有一定的参考价值,感兴趣的小伙伴们可以参考一下
这个日历采用小程序组件化开发,有兴趣的同学可以引用本组件(怎么引用不多赘述,自行去微信小程序开发api了解)
wxml
<!--pages/ponents/calender.wxml--> <view class='calender'> <view class='operate'> <text catchtap='reduce'>减少</text> <text catchtap="add">增加</text> </view> <view class='year'> <text>{{year}}年</text> <text>{{currentMonth}}月</text> </view> <view class='week'> <block wx:for="{{weekArr}}" wx:key="{{index}}"> <text>{{item}}</text> </block> </view> <view class='date'> <block wx:for="{{dateArr}}" wx:key="{{index}}"> <text>{{item-(weekNum-1)<=0?"":item-(weekNum-1)>yearMonth[currentMonth-1]?"":item-(weekNum-1)}}</text> </block> </view> </view>
