这个效果怎么做的? 100 分

NB 绝对不敢当，不过我觉得既然有例子，还是自己研究能学到东西~
http://www.nova.gov.cn/about/
这个页比较简单，你把它存下来研究下吧~

这种方法我知道,可好象 www.hzcnc.com 里用不同方法他是用<script language="javascript" src="script/moveleft.js"></script>
<script language="javascript" src="script/admoveright.js"></script>
<script language="javascript" src="new_include/moveleftq.js"></script>
<script language="javascript" src="new_include/admoverightq.js"></script>这些来实现的吗?

不好意思,JS 不懂的. 只知道套套用.<script language="javascript" src="new_include/admoverightq.js"></script>这种方法和直接写在 <head> 里是一样的吗? 是不是只是表现方式不一样.还是本质不同?

这样只是把那些javascript代码集中放在一个文件里，方便调用而已~
与方法本身没关系~

我收集的几个(自己还不会编):
