一個很Cool的JS菜單效果_javascript技巧

簡單地寫一個使用說明:
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：默認為空，既不在本頁打開；"_blank"代表在新的頁面打開
　例如:
CoolMenu2.insertmenu("2"," 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"既為完全透明
　例如:
CoolMenu1.init("CoolMenu1","#002000","#38FFff",0.1,15)
<script> function CoolMenuControl(){ //-----常規變量--- this.lastScrollX=0; this.lastScrollY=0; this.lastScrollW=0; this.lastScrollH=0; this.td_X=0; this.td_Y=0; this.td_W=0; this.td_H=0; this.td=0; this.mouseon=0;
