dreamweaver中如何外部调用JS特效
引用外部js文件，直接用script 标签引就可以了！
代码如下：
!DOCTYPE html
html
head
meta http-equiv="Content-Type" content="text/html; charset=utf-8" /
title无标题文档/title
script src="jquery-1.7.2.js" type="text/javascript"/script
script
//这里是其它的代码。这个就是用DW写的程序。
/script
src:是你引用js文件的路径+文件名。
type: 是声明类型。这里是javascript文件。
如果无法正常显示，看一下src的路径是否正确。
导航条js+css特效代码怎么用
导航条js+css特效一般都用于首页index文件，作为网站的主页栏目导航。
1、打开Dreamweaver创建新页面，输入以下代码。如图：
!DOCTYPE html PUBliC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"
html xmlns="
head
meta http-equiv="Content-Type" content="text/html; charset=gb2312" /
script src="

style type="text/css"

2、点击F12预览导航效果。如图：
注意事项：代码中的导航分为一级导航和二级感应导航，直接修改为所需栏目名称即可使用。
寻网页中JS实现的图片切换特效
我修改测试通过一个。但是有个问题。若改成鼠标悬停边缘滚下去，也就是onMouseOver。是停不下来的，会一直滚下去，因为无论怎么样都是鼠标碰触事件。所以我强烈建议用点击事件,onclick。
js css image都是调用的。我都写到页面里了，你自己改下。图片地址我没改。本地测试的。自己换成你的图片。
