一.
表格的行数问题
1.首先取得处理月的总天数
JS不提供此参数，我们需要计算。考虑到闰年问题会影响二月份的天数，我们先编写一个判断闰年的自编函数：
function
is_leap(year)
{
return
(year%100==0?res=(year%400==0?1:0):res=(year%4==0?1:0))
}
接着定义一个包含十二个月在内的月份总天数的数组：
m_days=new
Array(31,28+is_leap(ynow),31,30,31,31,30,31,30,31,30,31)
m_days这个数组里，二月份的天数已经加入闰年的信息：28+is_leap(ynow)。数组元素从0开始，正好对应于JS提供的Date函数提供的getMonth返回值，即0表示一月，1表示二月，2表示三月，依此类推。
这样，各月总数可以这样取得：m_days[x]。其中，x为0至11的自然数。
2.计算处理月第一天是星期几
可以使用Date函数的getDay取得，返回的值从0到6，0表示星期一，1表示星期二，2表示星期三，其余依此类推。代码如下（假设要处理的时间为2008年3月）：
n1str=new
Date(2008,3,1)
firstday=n1str.getDay()
有了月总天数和该月第一天是星期几这两个已知条件，就可以解决表格所需行数问题：（当前月天数+第一天是星期几的数值）除以七。表格函数需要整数，因此，我们使用Math.ceil来处理：
tr_str=Math.ceil((m_days[mnow]
+
firstday)/7)
表格中的tr标签实际上代表表格的行，因此变量tr_str是我们往下写表格的重要依据。
二.
打印日历表格
可以使用两个for语句嵌套起来实现：外层for语句写行，内层for语句写单元格。
for(i=0i<tr_stri++)
{
//外层for语句
-
tr标签
document.write("<tr>")
for(k=0k<7k++)
{
//内层for语句
-
td标签
idx=i*7+k
//表格单元的自然序号
date_str=idx-firstday+1
//计算日期
//这里是处理有效日期代码
}
//内层for语句结束
document.write("</tr>")
}
//外层for语句结束
单元格的自然序号是否代表有效日期非常关键，为此必须加入一个过滤机制：仅打印有效的日期。有效的日期大于0小于小于等于处理月的总天数。
