Java- Copy text area into disabled text area

javahelpneeded

<tr>
<td align="right" valign="center" width="100" height="50"><B> Name:</B></td>
<td valign="center"><input type="text" name="userName" size="30" maxlength="26"></td>
<td valign="center"><input type="text" name="userName"size="30" maxlength="26" disabled></td>

How do I copy the name inputed in the text field- automatically into the disabled area.
For example, I'm typing "Sarah" in the text field, and I want it to say "SaraH" in teh disabled- read only field- on the form.

How do I do this?
What function would enable me to do this?
Please reply ASAP! i really need help= as this is a part of my assignemnt!

you can use javascript :

for example

Code:

<HTML>
<HEAD>
<SCRIPT LANGUAGE="JavaScript">
<!-- Beginning of JavaScript -
function myfunction () {
document.getElementById('mytest').value= ' your message ';
// do something. 
}
// - End of JavaScript - -->
</SCRIPT>
</HEAD>
<BODY>
 
 <TEXTAREA id="mytest" />
<INPUT id="text" TYPE="text"   VALUE="Change me"  onchange="myfunction()">
 
</BODY>
</HTML>
