------解决方案--------------------onkeyup
------解决方案-------------------- <SCRIPT>  
 function checkKey() 
 { 
 if (window.event.shiftKey)  // checks whether the SHIFT key  
 						    // is pressed 
    { 
    txtOutput.value =  "true "; // returns TRUE if SHIFT is pressed  
 						     // when the event fires 
    } 
 } 
  </SCRIPT>  
  </HEAD>  
  <BODY>  
  <P> Press the SHIFT key while pressing another key. <BR>  
      <INPUT TYPE=text NAME=txtEnterValue onkeypress= "checkKey() ">  
  <P> Indicates  "true " if the shift key is used. <BR>  
      <INPUT TYPE=text NAME=txtOutput>  
  </BODY>
------解决方案---------------------_-!!!只是给你个例子,你可以写成 
 this.txtEmail.Attributes.Add( "onkeyup ",  "javascript:confrm(); ");
