這篇文章主要介紹了overlib用法,結合實例較為詳細的分析了JavaScript插件overlib的相關使用技巧,需要的朋友可以參考下

本文實例講述了overlib用法。分享給大家供大家參考，具體如下：

overLIB 是一個生成提示框與彈出菜單等頁面效果的一段非常優(yōu)秀的JS代碼。

它可以簡單的通過設置一些參數(shù)或命令來改變彈出頁面的款式、皮膚與形狀,不但如此，它還提供了非常簡單的擴展功能，來足客戶的不同需求。

overLIB 使用非常的簡單。

一、在<head></head> 標簽內(nèi)添加：

復制代碼代碼如下:

<script type="text/javascript" src="overlib.js"><!-- overLIB (c) Erik Bosrup --></script>

二、在<body></body>標簽內(nèi)添加：

復制代碼代碼如下:

<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、生成兩種不同款式(popup與sticky)的彈出頁面

<a href="javascript:void(0);" onmouseover="return overlib('這是一個popup.');" onmouseout="return nd();">popup示例</a>
<a href="javascript:void(0);" onmouseover="return overlib('這是一個sticky',STICKY, MOUSEOFF);" onmouseout="return nd();">stick示例 </a>

四、命令與參數(shù)

overLIB 可以接受任意個命令和參數(shù)。格式如下：命令[,'命令參數(shù)']

<a href="javascript:void(0);" onclick="return overlib('This is a sticky with a caption. And it is centered under the mouse!', STICKY, CAPTION,
'Sticky!', CENTER);" onmouseout="nd();">Click here!</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>無標題文檔</title>
</head>
<body>
<ahref="#" onclick="return overlib('使用overlib的命令', CAPTION, '這是Caption命令，就是生成頭部',HAUTO);"" onmouseout="return nd();">彈出測試</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);">指定大小與位置彈出</a>
<ahref="javascript:void(0);" onclick="return overlib('Setting size and posiztion!', STICKY, CAPTION,'Sticky!',STATUS ,'Hello');">設置狀態(tài)欄</a>
</body>
</html>

六、自定義overlib。overlib有三種方式可以實現(xiàn)自定義。

1、我們上面用過的通過輸入不同命令來實現(xiàn)自定義。
2、修改overlib.js中的默認值來實現(xiàn)自定義
3、在引用的頁面指定變量來實現(xiàn)自定義。
