用框架了，想在左侧的框架里做个菜单，但做出来发现弹出的菜单被框架挡住了……
不过现在好了，用下面这种方法菜单就不会受到框架的影响了，呵呵
首先，建立一个框架集
<html><head><meta http-equiv="Content-Type" content="text/html; charset=gb2312"><title>无标题文档</title></head><frameset cols="80,*" frameborder="NO" border="0" framespacing="0"> <frame src="FrameLeft.aspx" name="leftFrame" scrolling="NO" noresize> <frame src="FrameMain.aspx" name="mainFrame"></frameset><noframes><body></body></noframes></html>建立左侧菜单页FrameLeft.aspx

<script type="text/javascript">... 
var oPopup = window.createPopup(); function richContext() 
...{ var lefter2 = event.offsetY+0; var topper2 = event.offsetX+15; oPopup.document.body.innerHTML = divPM.innerHTML; oPopup.show(topper2, lefter2, 210, 84, link1); 
} </script> </head> <body> <table border="0" cellpadding="0" cellspacing="0"><tr><td> <a id="link1" href="#" class="c" onclick="richContext(); return false;" onmouseover="richContext(); return false;">一级菜单</a> <div id="divPM" style="display:none;"> <div style="position:relative; top:0; left:0; border:2px solid #FF9900; border-top:2px solid #FF9900; border-left:2px solid #FF9900; background:#FF9900; height:40px; width:210px;"> <div style="position:relative; top:0; left:0; background:#FFFF99; border:1px solid #FF9900; height:18px; color:black; font-family:宋体; padding:2px; padding-left:10px; font-size:12px; cursor:hand" onmouseover="this.style.background='#FF9900'; this.style.color='#ffffff'; this.style.border='1px solid #ffffff';" onmouseout="this.style.background='#FFFF99'; this.style.color='#000000'; this.style.border='1px solid #FF9900';" onclick="window.parent.oPopup.hide(); "> 一级菜单之子菜单1</div> <div style="position:relative; top:0; left:0; background:#FFFF99; border:1px solid #FF9900; height:18px; color:black; font-family:宋体; padding:2px; padding-left:10px; font-size:12px; cursor:hand" onmouseover="this.style.background='#FF9900'; this.style.color='#ffffff'; this.style.border='1px solid #ffffff';" onmouseout="this.style.background='#FFFF99'; this.style.color='#000000'; this.style.border='1px solid #FF9900'; " onclick="window.parent.oPopup.hide();"> 一级菜单之子菜单2</div> </div> </div></td></tr></table></body> </html>这样的菜单就不会被框架挡住喽~~~
