一個很Cool的JS菜單效果(類似flash)

一個使用說明:
第一步：實體化X-Menu類
   用法:
   var <實體變量>.new CoolMenuControl()

第二步：建立菜單項目---
  
  用法:
    <實體變量>.insertmenu(類型,Html代碼,鏈接網址,目標)
    　類型：０代表菜單標題，１代表樹型菜單子項目，２代表橫向菜單子項目
    　Html代碼：顯示在菜單上的Html代碼
      鏈接網址：不用多說了，網址或Javascript腳本
      目標：默認爲空，既不在本頁打開；"_blank"代表在新的頁面打開
　例如:     
    CoolMenu2.insertmenu("2","<img src=http://www.blueidea.com/img/icon/arrow.gif> 新浪網","http://www.sina.com.cn/","_blank")  　

第三步：建立菜單---
  
  用法:
    <實體變量>.init(實體變量名,邊框顏色,背景顏色,滑動速度,背景半透明度)
       '實體變量名'必須與<實體變量>相同
       如果背景顏色="transparent"既爲完全透明
　例如:     
    CoolMenu1.init("CoolMenu1","#002000","#38FFff",0.1,15)  　

源代碼如下

<script>
function CoolMenuControl(){
