禁止页面刷新,包括鼠标\键盘\F5,如何实现?

Question

showModalDialog('ttt.htm','','dialogWidth: 480px; dialogHeight: 360px; status: no; help: no');
showModelessDialog('ttt.htm','','dialogWidth: 480px; dialogHeight: 360px; status: no; help: no');
用模态框弹出来的页面, 用户就没有办法刷新了.

随便测试
<SCRIPT LANGUAGE="JavaScript">
<!--
function KeyDown(){
   if ((window.event.altKey)&&((window.event.keyCode==37)||(window.event.keyCode==39))){ 
      event.returnValue=false;
   }
   if((event.keyCode==116)||(event.ctrlKey && event.keyCode==82)){
      event.keyCode=0;
      event.returnValue=false;
   }
   if ((event.ctrlKey)&&(event.keyCode==78)){   
      event.returnValue=false;
   }
   if ((event.shiftKey)&&(event.keyCode==121)){ 
      event.returnValue=false;
   }
   if (window.event.srcElement.tagName == "A" && window.event.shiftKey){ 
      window.event.returnValue = false; 
   }
  if ((window.event.altKey)&&(window.event.keyCode==115)){
      window.showModelessDialog("about:blank","","dialogWidth:1px;dialogheight:1px");
      return false;
  }
}
document.onkeydown=KeyDown;function Click(){
window.event.returnValue=false;
}
document.oncontextmenu=Click;
