闲来无事做一些简单功能，一边练习VUE的使用，一边锻炼逻辑思维能力。之前有个项目需要自己写一个月份选择器，由此想起来做一个简单的日历，做起来有一些自己感兴趣的东西，也为了记录一下，发个帖

首先，我做的日历是没有农历的，因为我不知道农历的历法是怎么计算的，从网上找了一个似乎是很多年前的代码，功能不错，代码太乱就自己整理了一下，当然这段代码还是归写代码的大神所有，跟我没啥关系，特此声明

1、分享代码

Html代码

<template>
  <div class="main">
    <div class="choose_year">
      <div class="icon" @click="chooseYears(-1)"><i class="fa fa-angle-double-left"></i></div>
      <div class="icon" @click="chooseMonth(-1)"><i class="fa fa-angle-left"></i></div>
      <div class="date">{{year}}.{{month.toString().padStart(2, '0')}}</div>
      <div class="icon" @click="chooseMonth(1)"><i class="fa fa-angle-right"></i></div>
      <div class="icon" @click="chooseYears(1)"><i class="fa fa-angle-double-right"></i></div>
    </div>
    <div class="days_area">
      <div class="day week" v-for="week in weeks" :key="week">{{week}}</div>
      <div class="day" @click="chooseThisDay(day.gregorian)" v-for="(day, index) in days" :key="index" :class="day.gregorian === today ? 'choose_day' : ''">
        <p>{{day.gregorian}}</p>
        <span>{{day.lunar}}</span>
      </div>
    </div>
  </div>
</template>

SCSS代码

<style lang="scss" scoped>
  .main{
    .choose_year{
      display: flex;
      .icon{
        width: 10%;
        height: 8vh;
        line-height: 8vh;
        text-align: center;
      }
      .date{
        width: 60%;
        text-align: center;
        height: 8vh;
        line-height: 8vh;
        font-size: 1.2rem;
      }
    }
    .days_area{
      display: flex;
      flex-wrap: wrap;
      .day{
        width: 14.28%;
        text-align: center;
        padding: 1vh 0;
        margin-top: 1vh;
        p{
          margin: 0;
          font-size: 6vw;
        }
        span{
          font-size: 3vw;
        }
      }
      .week{
        background-color: dodgerblue;
        color: #fff;
        font-weight: bold;
        height: 6vh;
        line-height: 4vh;
        margin: 0;
      }
      .choose_day{
        background-color: dodgerblue;
        color: #fff;
        font-weight: bold;
      }
    }
  }
</style>

效果图



 

当然效果很一般啦，如果你要这种日历的话，自己精心调校一下样式应该...也比我好不到哪里去吧，哈哈哈哈

          cDayStr = numString.charAt((cDay - 1) % 10)
        }
        return cDay === 1 ? monString.charAt(cMonth - 1) + '月' : (cDay < 11 ? '初' : (cDay < 20 ? '十' : (cDay < 30 ? '廿' : '三十'))) + cDayStr // tgString.charAt((cYear - 4) % 10) + dzString.charAt((cYear - 4) % 12) + '年 ' + run + monString.charAt(cMonth - 1) + '月' +
      }
    },
    getBit (m, n) { // 也是拷贝的，不是很明白这段代码干嘛的，不过很明显是处理二进制数据的
      return 29 + ((m >> n) & 1)
    }
  }
}

OK，代码就这些，有需要的话随便取用，除了我也不是很明白的农历日期计算之外，其他都是我写得简单代码，没什么技术含量，也就不需要赘述了

			

				带农历日历的DatePicker控件！Xamarin控件开发小记
			
	
	

		
原文:带农历日历的DatePicker控件！Xamarin控件开发小记
闲来无事开发了个日期选择控件，感兴趣的同学前往：
https://github.com/MatoApps/Mato.DatePicker
Mato.DatePicker

说明
这是一个带有农历日历的日期选择Xamarin控件
可以指定初始日期
多选和单选日期
引用
PCL：https://www.nuget.org/packages/Mato.DatePicker.PCL/
Android：https://www.nuget.org/packages/Mato.DatePicker.Android/
iOS: https://www.nuget.org/packages/Mato.DatePicker.iOS/
用法
在引用iOS安装包时候需要在AppDelegate.cs做如下操作：

public override bool FinishedLaunching(UIApplication app, NSDictionary options)
{
...
    global::Xamarin.Forms.Forms.Init();   
    Mato.DatePicker.iOS.ChinaDateServer ssChinaDateServer=new Mato.DatePicker.iOS.ChinaDateServer(); //在此插入这段语句
    LoadApplication(new App());
}

 
同样的，在引用Android安装包后，需要在MainActivity.cs做如下操作：

protected override void OnCreate(Bundle bundle)
{
...
    global::Xamarin.Forms.Forms.Init(this, bundle);
    DatePicker.Android.ChinaDateServer ssChinaDateServer = new DatePicker.Android.ChinaDateServer(); //在此插入这段语句
    LoadApplication(new App());
}

 
在这个页面中提供了如何使用这一控件https://github.com/MatoApps/Mato.DatePicker/blob/master/Mato.Sample/Mato.Sample/MainPage.xaml

网上农历算法很多，大部分都是比较准的，但是在Qt里面很少有朋友整理和共享出来，在此，花一点时间整理下资料和想法，顺便或许也能帮助一些新手朋友！
首先讲讲设计思路吧，没有采用系统自带的QCalendarWidget，而是通过42个QLabel拼凑出来的一个界面，之所以采用这种拼凑的方法是方便管理样式，话不多说了上图和代码吧：



先来界面布局代码吧：
