Sample Code

<HEAD>
<SCRIPT>
var sNewValue = "copy event fired";
var bFired = false;
var sSave = "";

function Source_Beforecopy() 
{
  sSave = oSource.innerText;
  bFired = true;
  event.returnValue = false;
}

function Source_Copy() 
{
  window.clipboardData.setData("Text", sNewValue);
}

function Target_BeforePaste() 
{
  event.returnValue = false;
}

function Target_Paste() 
{
  event.returnValue = false;
  oTarget.value = window.clipboardData.getData("Text");
}

</SCRIPT>
</HEAD>
<BODY>
<SPAN ID=oSource onbeforecopy="Source_Beforecopy()"
       oncopy="Source_Copy()">copy this text</SPAN>
<INPUT ID=oTarget onbeforepaste="Target_BeforePaste()"
