/**//* 控件使用方法：
        1. 頁頭加入代碼：<script language='javascript' src="./Calendar_HY.js" /> （此處假設頁面與本文件在同一目錄，否者請自行修改引用路徑。）                                
                                       <script language='javascript'></script>
        2. 觸發控件中加入ONCLICK事件：onclick="showDiv2(this)"
             如已存在ONCLICK事件則只要在調用的函數裏直接調用 showDiv2(this); 即可。
