母版页上的控件　在内容页是子文件夹内的页时　无法执行javascript?

当内容页与母版页在同一级文件夹时，母版页上的控件可以触发.js页上的事件，但当内容页在母版页所在的子文件夹时就缺少对象，这个js是为了弹出一个登录框。。
请高手赐教：

是不是相对路径的问题？
母板页的使用，不是把子页引入到母页，而是把母页应用到子页
所以你在母板中引用的文件最好用绝对路径
比如你的:
<link type="text/css" href="/StyleSheet.css" rel="stylesheet" />
<script type="text/javascript" src="/JScript.js" > </script>
