此乃层的隐藏与显示也， 一、点击左边的缩进图片，左边栏收缩 二、实现的思路 1、图片作为按扭，点击图片触发层的显示和收缩，图片代码如下: <A href="javascript:show()"><IMG src="image/fclose.gif" align="absmiddle" border="0"></A>三、源代码 <HTML><HEAD><META http-equiv="Content-Type" content="text/htmlcharset=gb2312"><TITLE>收缩左边栏效果</TITLE><STYLE type="text/css">td{font-size:12pxline-height:22px} .red{color: #FF0000} </STYLE><SCRIPT language="JavaScript">function show(){ if(document.getElementById("left").style.display=='none'){ //判断目前左边栏的状态(显示、隐藏) document.getElementById("left").style.display='block'//显示左边栏 } else{document.getElementById("left").style.display='none'//隐藏左边栏} } </SCRIPT></HEAD><BODY><TABLE width="98%" border="0" cellspacing="0" cellpadding="0" align="center"><TR><TD id="left" width="200">点点右边的收缩按钮，看看我是不是进去了!</TD><TD width="8" style="border-right:1 #cccccc solid"><A href="javascript:show()"><IMG src="image/fclose.jpg" align="absmiddle" border="0"></A></TD><TD valign="top">右侧</TD></TR></TABLE> </BODY></HTML><html>

不能出现在浏览器的
地址栏
中出现，因为HTML
中
标签定义
frameset
中的一个特定的窗口，你的获取的路径只能在窗体上显示，而其具体路径不能在地址栏中显示
如果，感觉有用，请采纳，谢谢！！
