Problem with submit.........

Is there a Java script event handler that get fired, when a user presses the return key (enter) while using my JSP screen. Because,
i just seem to get my error page (JSP), if the user presses enter key, instead of the
submit button(or <input type="button">

All ideas will be appreciated !!!

Well, you can certainly capture the key event but I don't think that's the right thing to do.
The form itself has an on_submit handler (minus the _) that you can use to validate that the values to be submitted are "legal".
First thing I'd do is to debug the servlet (or whatever backend component you are using) to find out why it is blowing up when you submit the form via the return key vs. your button. Then you can either deal with the situation which causes the error in an intelligent fashion either on the server side or on the client side (or both).

hi gabriel,
there is a keyCode-attribute (window.event.keyCode) you could use. but as far, as i know it will only work in ie. netscape-browsers can't handle it.
maybe you can solve your problem by setting the focus-attribute manually:

check where the focus is, when you hit enter.

Netscape CAN handle it if you use the right code for netscape.
post the code for the submitting of your form.

This code handles IE4+,NS4, NS6+.
It will submit a given form if enter pressed.
If you want to submit a form only if user pressed enter on the form element, you need to get a form usling window.event.srcElement.form for IE , and (I think, I remember correctly ) e.target.form for NS, into an if statement.
function NSkeypress(e)
{
if (e.which == 13) {
top.document.MyForm.submit();
}
return true;
}
function IEkeypress()
{
if (window.event.keyCode == 13) {
top.document.MyForm.submit();
}
return true;
}

//define event handlers
if (document.getElementById&&!document.all) {
// NS6 - not sure,that you need to use a captureEvents
document.captureEvents(Event.KEYPRESS);
document.onkeypress= NSkeypress;
}
if (document.layers) {
document.captureEvents(Event.KEYPRESS);
document.onkeypress= NSkeypress;
}
if (document.all) {
document.onkeypress=IEkeypress;
}

Hello, the IE version works fine , but what is the actual value of the parameter, i could not get this in my Javascript reference.
i.e. value of e and e.which in the function below
function NSkeypress(e)
{
if (e.which == 13) {
top.document.MyForm.submit();
}
return true;
}
Cheers.

It is an event object, it would be passed by browser, when it calles your event handler

Thanks very much Yuriy.
