仿屏幕保护

不要触动鼠标，5秒后即可启动“屏幕保护”画面。到时触动鼠标，又即刻返回本页。
这个脚本须要制作两个网页，即原网页与“屏幕保护”效果网页。

安装
步骤一  拷贝以下脚本后贴在原网页的<head></head>之间。


<script language="JavaScript">  </script>

步骤二  把下列代码放置在<body>的标记内。
onblur="blurred='1'" onfocus="blurred='0';oActive()"

样板：
<body onblur="blurred='1'" onfocus="blurred='0';oActive()">
步骤三  下载以下五个星球图像，存放在与相关网页同一个文件夹内。


步骤四  拷贝以下脚本后贴在另一个将作为“屏幕保护”效果的网页的<head></head>之间。(为配合本示范脚本，应定该网页名称为pinmu_baohu2.html)

就是如此简单！
