时间：2021-05-26

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：复制代码 代码如下:<script type="text/javascript" src="overlib.js"><!-- overLIB (c) Erik Bosrup --></script>
二、在<body></body>标签内添加：复制代码 代码如下:<div id="overDiv" style="position:absolute; visibility:hidden; z-index:1000;"></div> 4.10以上的版本可省略此步

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>
