前言
本以为这是一个很简单的功能,几分钟就搞定。没想到,还是很麻烦的!记录一下开发过程。
这里就涉及到了设计模式的一些知识,如果使用静态的代码,几乎 1000 行,这样大学生 10W 的代码岂不是很容易完成?但如果采用动态的方式,估计至少要减少一半无用的代码,还没改掉。继续前进!
使用了 Element-ui 的 Select 选择器,不过似乎有些鸡肋,感觉用下拉框就可以解决了,而且饿了么 ui 的选择器感觉也不是很好看。
1 区分月份的天数
每个月的每一天都是不一样,大月 31 天,小月 30 天,二月最为特殊,平年 28 天,闰年 29 天。
科普时间:为什么隔三年二月就会多一天?
这个知识是我从汉书中得到答案的,一笑。汉朝的历法划分一年为 365.25 天,那么四年就会多出一天,这一天也就是闰年二月多出来的一天。
1.1 思路
这里用的很暴力的方式,每一个月份都用一个静态的数组赋值.
1.2 好处
新手都可以上手
操作简单,直接复制、粘贴,稍微改动即可,
1.3 缺点
可维护性差,改变一点东西,需要把全部月份的情况进行改动
代码冗长,可读性不好
1.4 效果
9 月份为 30 天
10 月份为 31 天
2 区分闰年和平年
2.1 思路
C++敲烂了的代码终于派上了用场
if(year%400==0||(year%4==0&&year%100!=0))
{
cout<<"这是闰年";
}else{
cout<<"这是平年";
}
3 年份月份修改导致的问题
如下图:1 月份有 31 天,但是 2 月最多只有 29 天,这个问题怎么解决?
3.1 思路
设置一个修改月份的函数,一个修改年份的函数。
当修改月份的时候,查看当前的 day 是否大于了该月份所有的最大的天数(这里也涉及了平闰年的问题),如果大于则将该天数设置为修改月份所有的最大天数。如果不大于则不须修改。修改年份的时候也会出现这种情况,当然只涉及 2 月。
也就有以下三种情况:
当前天数大于月份的最大天数,天数截取(如 1 月有 31 天,修改成 4 月,应变为 30 天),天数重置(如 1 月 31 日,月份变为 2 月,则天应该随之变为 30)
当前天数小于月份的最大天数,不动。
月份为 2,闰年平年转换,参考第一种情况解决。
3.2 效果图
4 禁用未到达的时间
4.1 思路
这个问题的解决是比较麻烦的,但也无非有一下几种情况
本年不显示未到的月数
本年不显示未到的天数(针对本月)
年份的改变导致月数、天数的变化
月份的转变导致天数的变化
