本文實例講述了JS實現(xiàn)帶陰歷的日歷功能。分享給大家供大家參考，具體如下：

工作中要寫一個帶陰歷的日歷，自己調(diào)研了怎么做日歷。

一.表格行數(shù)問題

既然要顯示日期表格的話，首先得知道這個表格有多少行多少列，列數(shù)是已經(jīng)確定的，從星期天（日歷上第1列是星期天）到星期六一共7列。要解決行數(shù)問題之前，還得先知道這個月的第1天是星期幾，因為每個月的1號并不都是從日歷上的星期天開始排的，可能1號是星期五，星期六也說不定，所以1號的左邊部分，就得用空表格代替了。那么用多少個空表格代替呢，這里就得用到getDay()方法了，該方法返回數(shù)組[0-6]中的一個數(shù)字，0代表星期天，1代表星期一，2代表星期二，以此類推。所以如果一個月的1號是星期五的話，那么剛好左邊需要5個空表格代替。然后，假如一個月有31天，最后求出的表格行數(shù)就是：

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

當然，并不是每個月都是31天，所以我們得創(chuàng)建一個包含12個月份的數(shù)組，每個元素代表每個月份所包含的天數(shù)。但是2月份比較特殊，閏年的2月份有29天，平年的2月份只有28天。所以，在創(chuàng)建數(shù)組之前，得自己創(chuàng)建一個判斷閏年的函數(shù):

//如果當前年份能被4整除但是不能被100整除或者能被400整除，即可確定為閏年，返回1，否則返回0function isLeap(year) { return year % 4 == 0 ? (year % 100 != 0 ? 1 : (year % 400 == 0 ? 1 : 0)) : 0; }

然后我們創(chuàng)建一個月份數(shù)組:

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

這樣就能保證無論是平年還是閏年都會取出正確的天數(shù)，下面的代碼用于獲取今天的相關(guān)信息:

var today = new Date(),       //獲取當前日期y = today.getFullYear(),     //獲取日期中的年份m = today.getMonth(),      //獲取日期中的月份(需要注意的是：月份是從0開始計算，獲取的值比正常月份的值少1)d = today.getDate(),       //獲取日期中的日(方便在建立日期表格時高亮顯示當天)firstday = new Date(y, m, 1),  //獲取當月的第一天dayOfWeek = firstday.getDay(),  //判斷第一天是星期幾(返回[0-6]中的一個，0代表星期天，1代表星期一，以此類推)days_per_month = new Array(31, 28 + isLeap(y), 31, 30, 31, 30, 31, 31, 30, 31, 30, 31), //創(chuàng)建月份數(shù)

所以最后就可以獲取當月所需表格的行數(shù):

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

完整的js代碼：

<script>  //判斷當前年份是否是閏年(閏年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(), //獲取當前日期  y = today.getFullYear(), //獲取日期中的年份  m = today.getMonth(), //獲取日期中的月份(需要注意的是：月份是從0開始計算，獲取的值比正常月份的值少1)  d = today.getDate(), //獲取日期中的日(方便在建立日期表格時高亮顯示當天)  firstday = new Date(y, m, 1), //獲取當月的第一天  dayOfWeek = firstday.getDay(), //判斷第一天是星期幾(返回[0-6]中的一個，0代表星期天，1代表星期一，以此類推)  days_per_month = new Array(31, 28 + isLeap(y), 31, 30, 31, 30, 31, 31, 30, 31, 30, 31), //創(chuàng)建月份數(shù)組  str_nums = Math.ceil((dayOfWeek + days_per_month[m]) / 7); //確定日期表格所需的行數(shù)  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(顯示星期)  for (i = 0; i < str_nums; i += 1) { //二維數(shù)組創(chuàng)建日期表格  document.write('<tr>');  for (k = 0; k < 7; k++) {   var idx = 7 * i + k; //為每個表格創(chuàng)建索引,從0開始   var date = idx - dayOfWeek + 1; //將當月的1號與星期進行匹配   (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>'); //高亮顯示當天  }  document.write('</tr>');  }  document.write('</table>');</script>

二、陰歷的問題

從小就沒搞懂了陰歷和陽歷中的換算問題，幸運的是從其他牛人那里找到了陰陽歷的轉(zhuǎn)換js代碼，

使用的方法是：
