/**
文件: 197:8008/library/script/calendar.js, 1 tab indent, CR LF, UTF-8, no-BOM
模块: 日历[Module.calendar]
更新: 9:49 2007-2-27
用法: 
oneCalendar.showCalendar("添加日历的id", 月(0~11), 年, 日(1~31));
oneCalendar 是默认初始生成的，日历中没有点击功能
可以用下面2 种方式生成自定义功能
calendar_day_click 在每天链接点击时调用，传入一个参数(类型: "2006-2-2")
calendar_day_link 是每天链接的href 值，传入一个参数(类型: "2006-2-2")
