如何让父窗口title动态等于子窗口的title
我知道用HtmlGenericControl可以动态改变title的文字,但是我不清楚怎么获取子窗口的title。 
 不想用Request.QueryString,感觉这个太麻烦,frame之间传值是不是有更方便的方法啊?JS实现也行的。 
 3Q先~
------解决方案--------------------main page: 
  <html>  
  <head>  
      <title id= "tt "> hello </title>  
  </head>  
  <body>  
  <input type= "button " value= "open " onclick= "toOpen(); "/>  
  <script language= "javascript ">  
     function toOpen() 
     { 
         window.open( "newPage.htm ", "_blank "); 
     } 
  </script>  
  </body>  
  </html>  
 ============== 
 child page: 
  <html>  
  <head>  
      <title id= "aa "> nihao </title>  
      <script language= "javascript ">  
         function changeParentTitle() 
         { 
             var win=window.opener; 
             win.document.title=document.title;            
         } 
      </script>  
  </head>  
  <body onload= "changeParentTitle(); ">  
  </body>  
  </html>
------解决方案--------------------好象答非所问哦.     
 你大概是问frame中的子窗口改变父窗口的title.   
 child page: 
  <html>  
  <head>  
      <title id= "aa "> nihao </title>  
      <script language= "javascript ">  
         function changeParentTitle() 
         { 
            window.top.document.title=document.title;            
         } 
      </script>  
  </head>  
  <body onload= "changeParentTitle(); ">  
  </body>  
  </html>  
------解决方案-------------------- <body onload= "changeParentTitle(); ">
