本文实例讲述了JS实现带阴历的日历功能。分享给大家供大家参考，具体如下：

工作中要写一个带阴历的日历，自己调研了怎么做日历。

一.表格行数问题

既然要显示日期表格的话，首先得知道这个表格有多少行多少列，列数是已经确定的，从星期天（日历上第1列是星期天）到星期六一共7列。要解决行数问题之前，还得先知道这个月的第1天是星期几，因为每个月的1号并不都是从日历上的星期天开始排的，可能1号是星期五，星期六也说不定，所以1号的左边部分，就得用空表格代替了。那么用多少个空表格代替呢，这里就得用到getDay()方法了，该方法返回数组[0-6]中的一个数字，0代表星期天，1代表星期一，2代表星期二，以此类推。所以如果一个月的1号是星期五的话，那么刚好左边需要5个空表格代替。然后，假如一个月有31天，最后求出的表格行数就是：


var tr_nums = Math.ceil((5 + 31)/7);

当然，并不是每个月都是31天，所以我们得创建一个包含12个月份的数组，每个元素代表每个月份所包含的天数。但是2月份比较特殊，闰年的2月份有29天，平年的2月份只有28天。所以，在创建数组之前，得自己创建一个判断闰年的函数:


//如果当前年份能被4整除但是不能被100整除或者能被400整除，即可确定为闰年，返回1，否则返回0
function isLeap(year) {
 return year % 4 == 0 ? (year % 100 != 0 ? 1 : (year % 400 == 0 ? 1 : 0)) : 0;
 }

然后我们创建一个月份数组:


var days_per_month = new Array(31, 28 + isLeap(year), 31, 30, 31, 30, 31, 31, 30, 31, 30, 31);

这样就能保证无论是平年还是闰年都会取出正确的天数，下面的代码用于获取今天的相关信息:


var today = new Date(), //获取当前日期
y = today.getFullYear(), //获取日期中的年份
m = today.getMonth(), //获取日期中的月份(需要注意的是：月份是从0开始计算，获取的值比正常月份的值少1)
d = today.getDate(), //获取日期中的日(方便在建立日期表格时高亮显示当天)
firstday = new Date(y, m, 1), //获取当月的第一天
dayOfWeek = firstday.getDay(), //判断第一天是星期几(返回[0-6]中的一个，0代表星期天，1代表星期一，以此类推)
days_per_month = new Array(31, 28 + isLeap(y), 31, 30, 31, 30, 31, 31, 30, 31, 30, 31), //创建月份数

所以最后就可以获取当月所需表格的行数:


var str_nums = Math.ceil((dayOfWeek + days_per_month[m]) / 7); //确定日期表格所需的行数

完整的js代码：


<script>
 //判断当前年份是否是闰年(闰年2月份有29天，平年2月份只有28天)
 function isLeap(year) {
 return year % 4 == 0 ? (year % 100 != 0 ? 1 : (year % 400 == 0 ? 1 : 0)) : 0;
 }
 var i, k,
 today = new Date(), //获取当前日期
 y = today.getFullYear(), //获取日期中的年份
 m = today.getMonth(), //获取日期中的月份(需要注意的是：月份是从0开始计算，获取的值比正常月份的值少1)
 d = today.getDate(), //获取日期中的日(方便在建立日期表格时高亮显示当天)
 firstday = new Date(y, m, 1), //获取当月的第一天
 dayOfWeek = firstday.getDay(), //判断第一天是星期几(返回[0-6]中的一个，0代表星期天，1代表星期一，以此类推)
 days_per_month = new Array(31, 28 + isLeap(y), 31, 30, 31, 30, 31, 31, 30, 31, 30, 31), //创建月份数组
 str_nums = Math.ceil((dayOfWeek + days_per_month[m]) / 7); //确定日期表格所需的行数
 document.write("<table cellspacing='0'><tr><th>日</th><th>一</th><th>二</th><th>三</th><th>四</th><th>五</th><th>六</th></tr>"); //打印表格第一行(显示星期)
 for (i = 0; i < str_nums; i += 1) { //二维数组创建日期表格
 document.write('<tr>');
 for (k = 0; k < 7; k++) {
 var idx = 7 * i + k; //为每个表格创建索引,从0开始
 var date = idx - dayOfWeek + 1; //将当月的1号与星期进行匹配
 (date <= 0 || date > days_per_month[m]) ? date = ' ': date = idx - dayOfWeek + 1; //索引小于等于0或者大于月份最大值就用空表格代替
 date == d ? document.write('<td class="today">' + date + '</td>') : document.write('<td>' + date + '</td>'); //高亮显示当天
 }
 document.write('</tr>');
 }
 document.write('</table>');
</script>

二、阴历的问题

从小就没搞懂了阴历和阳历中的换算问题，幸运的是从其他牛人那里找到了阴阳历的转换js代码，
