我有一个文本框，当我要在该文本框上写一些东西时，如果按TAB键，则会出现"请稍候"的警报，然后我想在该jsp页面或不同的jsp页面中显示输入的值，该警报即将到来，但输入的文本框值没有显示，如何做到这一点？

//a.jsp

<script type="text/javascript">
 var obj;
  var TAB = 9;
  function catchTAB(evt,elem)
  {
   obj = elem;
   var keyCode;
   if ("which" in evt)
    {// NN4 & FF &amp; Opera
     keyCode=evt.which;
   } else if ("keyCode" in evt)
    {// Safari & IE4+
  keyCode=evt.keyCode;
 } else if ("keyCode" in window.event)
 {// IE4+
keyCode=window.event.keyCode;
} else if ("which" in window.event)
{
 keyCode=evt.which;
} else  {    alert("the browser don't support");  }
 if (keyCode == TAB)
 {
 obj.value = obj.value + "'t";
 alert("Please wait");
 setTimeout("obj.focus()",1);// the focus is set back to the text input
}
}
</script>
<body>
 <input type="text" name="textboxname" onkeydown="catchTAB(event,this);"/>// after hitting TAB key i want to see that entered value in a.jsp page, how can i do it?
</body>

任何帮助

由于您能够捕获Tab事件，因此很容易从该事件中获取值并将其填充到页面中的任何位置。

     <script type="text/javascript">
 var obj;
  var TAB = 9;
  function catchTAB(evt,elem)
  {
   obj = elem;
   var keyCode;
   if ("which" in evt)
    {// NN4 & FF &amp; Opera
     keyCode=evt.which;
   } else if ("keyCode" in evt)
    {// Safari & IE4+
  keyCode=evt.keyCode;
 } else if ("keyCode" in window.event)
 {// IE4+
keyCode=window.event.keyCode;
} else if ("which" in window.event)
{
 keyCode=evt.which;
} else  {    alert("the browser don't support");  }
 if (keyCode == TAB)
 {
 obj.value = obj.value + "'t";
 alert("Please wait");
alert( obj.value);
document.getElementById('textboxNew').value = obj.value;
 setTimeout("obj.focus()",1);// the focus is set back to the text input
}
}
</script>
<body>
 <input type="text" name="textboxname" onkeydown="catchTAB(event,this);"/>// after hitting TAB key i want to see that entered 
value in a.jsp page, how can i do it?
<input type="text" name="textboxNew" id="textboxNew"/>
</body>
