onkeyPress event with Intro key doesn't work on Firefox

Hello!!

I am having a problem on firefox.
I have an event (onkeyPress) on a textarea, which should trigger a function when the key pressed is Intro.
I would have the following on HTML:

HTML Code:

.. <textarea id="idtextarea" onkeyDown="showUser(this.value)"></textarea> ...

In Javascript:

[Javascript]
function showUser(this.value)
{
var keycode;
if(window.event) keycode = window.event.keyCode;
else if (e) keycode = e.which;
else return true;
if (keycode == 13)
{
...

[/Javascript]

It works on the main browsers but Firefox. Nothing happens on this browser.

I would appreciate any help.
Thank you very much.

Try this

HTML Code:

<head> <script> function showUser(e){ alert(e) var keycode=e.which?e.which:e.keyCode; alert(keycode); } </script> </head> <body> <textarea id="idtextarea" onkeyDown="showUser(event)"></textarea> </body>

Thank you 007julien.
I have tried. It displays an alert.
But I don't know how to link that to my function. And couldn't I keep the (str)?
Because after what I have written above I try to find out (in the function) wheter that value is empty or not :

HTML Code:

... function showUser(str) { var keycode; if(window.event) keycode = window.event.keyCode; else if (e) keycode = e.which; else return true; if (keycode == 13) { if(str=="") { function showUser(str) { var keycode; if(window.event) keycode = window.event.keyCode; else if (e) keycode = e.which; else return true; if (keycode == 13) { var xmlhttp; if(str=="") { ....

You can keep the string with a

HTML Code:

<textarea id="idtextarea" onkeyDown="showUser(this.value,event)"></textarea>

And a script

Code:

<script type="text/javascript"> function showUser(str,e){ var keycode=e.which?e.which:e.keyCode; // To see what you get and to comment (//) or remove after debugging alert('The string '+str+'\nThe keyCode'+keycode); // do something with str and keycode // ... } </script>
