框架自动高度问题(在线等)
|      topframe      | 
 |____________| 
 |                                    | 
 |   mainframe      | 
 |                                    | 
 |                                    | 
 topframe高度是固定的200象素,要求mainframe高度随着内容的多少变化高度,不能出现滚动条,并且内容要显示完全。请问各位大哥大姐怎么实现啊?我的代码在下面: 
 topframe.html 
  <html>  
  <head>  
  </head>  
  <body>  
 test <br> test <br> test <br> test <br> test <br>  
  </body>  
  </html>  
 mianframe.html 
  <html>  
  <head>  
  </head>  
  <body>  
 test <br> test <br> test <br> test <br> test <br> test <br> test <br> test <br> test <br> test <br> test <br> test <br> test <br> test <br> test <br> test <br> test <br> test <br> test <br> test <br> test <br> test <br> test <br> test <br> test <br> test <br> test <br> test <br> test <br> test <br> test <br> test <br> test <br> test <br> test <br> test <br> test <br> test <br> test <br> test <br>  
  </body>  
  </html>    
 frame.html 
  <html   xmlns= "http://www.w3.org/1999/xhtml ">  
  <head>  
  <meta   http-equiv= "Content-Type "   content= "text/html;   charset=gb2312 "   />  
  <title> 无标题文档 </title>  
  </head>  
  <frameset   rows= "80,* "   frameborder= "no "   border= "0 "   framespacing= "0 ">  
        <frame   src= "topframe.html "   name= "topFrame "   scrolling= "No "   noresize= "noresize "   id= "topFrame "   />  
        <frame   src= "mianframe.html "   name= "mainFrame "   id= "mainFrame "   />  
  </frameset>  
  <noframes>  <body>  
  </body>  
  </noframes>  </html>
