本文实例讲述了overlib用法。分享给大家供大家参考，具体如下：
overLIB 是一个生成提示框与弹出菜单等页面效果的一段非常优秀的JS代码。
它可以简单的通过设置一些参数或命令来改变弹出页面的款式、皮肤与形状,不但如此，它还提供了非常简单的扩展功能，来足客户的不同需求。
overLIB 使用非常的简单。
一、在<head></head> 标签内添加：
三、生成两种不同款式(popup与sticky)的弹出页面
<a href="javascript:void(0);" onmouseover="return overlib('这是一个popup.');" onmouseout="return nd();">popup示例</a>
<a href="javascript:void(0);" onmouseover="return overlib('这是一个sticky',STICKY, MOUSEOFF);" onmouseout="return nd();">stick示例 </a>

五、 overlib的一些使用示例
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<scriptlanguage="JavaScript" src="overlib.js"></script><html>
<head>
<metahttp-equiv="Content-Type" content="text/html; charset=gb2312">
<title>无标题文档</title>
</head>
<body>
<ahref="#" onclick="return overlib('使用overlib的命令', CAPTION, '这是Caption命令，就是生成头部',HAUTO);"" onmouseout="return nd();">弹出测试</a>
<ahref="javascript:void(0);" onmouseover="return overlib('This is an ordinary popup.',CLOSECLICK);" onmouseout="return nd();">here</a>
<ahref="javascript:void(0);" onmouseover="return overlib('This is what we call a sticky, since I stick around (it goes away if you move the mouse OVER and then OFF the overLIB popup--or mouseover another overLIB).', STICKY, MOUSEOFF);" onmouseout="return nd();">吸附性的提示框</a>
<ahref="javascript:void(0);" onclick="return overlib('This is a sticky with a caption. And it is centered under the mouse!', STICKY, CAPTION,'Sticky!',CENTER);">含CAPTION的STICKY!</a>
<ahref="javascript:void(0);" onclick="return overlib('Setting size and posiztion!', STICKY, CAPTION,'Sticky!',HEIGHT, 100,WIDTH,120,LEFT);">指定大小与位置弹出</a>
<ahref="javascript:void(0);" onclick="return overlib('Setting size and posiztion!', STICKY, CAPTION,'Sticky!',STATUS ,'Hello');">设置状态栏</a>
</body>
</html>
六、自定义overlib。overlib有三种方式可以实现自定义。
1、我们上面用过的通过输入不同命令来实现自定义。
2、修改overlib.js中的默认值来实现自定义
3、在引用的页面指定变量来实现自定义。
