3、"自适应分辨率可扩展二层JS下拉菜单"js代码使用方法。
(1) 将上面的代码存储为js_daohang.js.放在和调用的页面同一个目录下。
(2) 在需要使用的叶面中在如下位置添加<script language=javascript src=js_daohang.js>
<html>
<head>
<title>平安证券柜台系统...</title>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<link rel="stylesheet" href="text.css" type="text/css">
<script language=javascript src=js_daohang.js>
</head>
