代码封装完成啦
在这里谢谢大家对我的支持！
偶参照一些Flash站点的菜单,
用javascript仿了一个,效果还是挺Cool的.
简单地写一个使用说明:
第一步：实体化X-Menu类
用法:
var <实体变量>.new CoolMenuControl()
第二步：建立菜单项目---
用法:
<实体变量>.insertmenu(类型,Html代码,链接网址,目标)
　类型：０代表菜单标题，１代表树型菜单子项目，２代表横向菜单子项目
　Html代码：显示在菜单上的Html代码
链接网址：不用多说了，网址或Javascript脚本
目标：默认为空，既不在本页打开；"_blank"代表在新的页面打开
　例如:
CoolMenu2.insertmenu("2","<img src=http://www.blueidea.com/img/icon/arrow.gif> 新浪网","http://www.sina.com.cn/","_blank") 　
第三步：建立菜单---
用法:
<实体变量>.init(实体变量名,边框颜色,背景颜色,滑动速度,背景半透明度)
'实体变量名'必须与<实体变量>相同
如果背景颜色="transparent"既为完全透明
　例如:
CoolMenu1.init("CoolMenu1","#002000","#38FFff",0.1,15)

点击运行可以看到效果:

<script>
