更新更强的日历脚本(downmoon)
第一步：将如下内容存为Calendar.js
document.write( " <div id=meizzCalendarLayer style='position: absolute; z-index: 9999; width: 144; height: 193; display: none'> " ); document.write( " <iframe name=meizzCalendarIframe scrolling=no frameborder=0 width=100% height=100%></iframe></div> " ); function writeIframe()
