微信小程序小应用:实现一个日历打卡的功能。我们先看看演示效果:
废话不多说啊,我们直接来看代码吧。
wxml
<view class="context"> <view class="top"> <image src="../../img/left.png" bindtap="bindPreMonth"></image> <view>{{year}}年{{month}}月</view> <image src="../../img/right.png" bindtap="bindNextMonth"></image> </view>
<view class="middle"> <view wx:for="{{data_arr}}" wx:key="index" class="middle_num"> {{item}} </view> </view>
<view class="calen">
<view wx:for="{{startWeek}}" wx:key="index" class="calen_blank"></view> <view wx:for="{{currentMonthDays}}" class='{{index+1 == today ? "active": "calen_num"}}' wx:key="index"> {{index+1}} </view> </view>
</view>
JS
Page({ /** * 页面的初始数据 */ data: { data_arr:["日","一","二","三","四","五","六"], year:"", month:"", today:2 //这是固定2号这天打开,连续几天打卡就用数组就好了 },
/** * 生命周期函数--监听页面加载 */ onLoad: function (options) { let now = new Date() let year = now.getFullYear() // month获取是从 0~11 let month = now.getMonth() + 1 this.setData({ year,month }) this.showCalendar() },
showCalendar(){ let {year,month} = this.data //以下两个month已经+1 let currentMonthDays = new Date(year,month,0).getDate() //获取当前月份的天数 let startWeek = new Date(year + '/' + month + '/' + 1).getDay(); //本月第一天是从星期几开始的 this.setData({ currentMonthDays,startWeek }) },
//上个月按钮 bindPreMonth(){ let {year,month} = this.data //判断是否是1月 if(month - 1 >= 1){ month = month - 1 }else{ month = 12 year = year - 1 } this.setData({ month,year }) this.showCalendar() },
//下个月按钮 bindNextMonth(){ let {year,month} = this.data //判断是否是12月 if(month + 1 <= 12){ month = month + 1 }else{ month = 1 year = year + 1 } this.setData({ month,year }) this.showCalendar() } })
