我修改后的JavaScript日历！ - eyoung

公告

很多人在做博客的时候都会在自己的页面里加入一个日历，最近我也给做的网站里加入了一个。先前在网上收索了一翻关于此的源代码，看了下效果，感觉大多不尽如人意。偶然在一国外的网站上看见了一个不错的日历，主要是通过JavaScript中嵌入CSS来实现的，其中插入相应的代码还可以链接到自己的文档，相对来说还不错了。源码经过我修改了一番，现在此贴出，与大家共享。

核心脚本文件代码如下：

// 头部区域class设置

document.write("<style type=text/css>\

页面调用：
在页面插入下列代码：

<!--

showCalendar("calendar");

-->

</script>

然后在需要调用日历的地方用下列代码调用。
