How disable the F5 key in Mozilla

Hi,
I am trying to disable the F5 key in Mozilla. I have the next code in
javascript that it is working in Internet Explorer but it is not
working in Mozilla. how can I disable the F5 key in Mozilla?

<script>
document.onkeydown = function(){

if(window.event && window.event.keyCode == 116){
window.event.keyCode = 505;
}
if(window.event && window.event.keyCode == 505){
return false;
}

}

</script>

You can find very simple solutions here:

Well, stop that then and fix the real problem, instead.

If refreshing breaks something, then attempting to prevent that action
doesn't fix anything. More importantly, you'll never really succeed:
there are other means besides F5, including other keystrokes, and it
will clearly do nothing for users with scripting disabled.

Finally, have you thought the consequences through properly? If a
document doesn't load completely due to network problems, but sufficient
data comes through to disable refreshing, what do you think the user
will do if they can't reload?

Good.
I have tried it but it don't work.
And that is how it should be.
Can you help me, please?


Redesign your app so that F5 doesn't fubar it.

The linked solution does work - unfortunately - even for the latest FF
1.5.0.4
Today later I'll file a bug to bugzilla so they fix it (unless there
are volunteers to do it immediately ?)

No, it does not "work" at all.
Today later I'll file a bug to bugzilla so they fix it (unless there
are volunteers to do it immediately ?)


To fix what? The ineptness of webpage authors that can't write a decent
app that won't die if the F5 key is pressed? Good luck with that but I
don't think filing with bugzilla can fix that problem.

Randy Webb & Michael Winter,
I think you are too close minded...

To disable the F5 key doesn't necessarily mean that
the programmer can't solve a "refresh issue".

e.g.
I'm moving a "mainframe application" to a web application.
I don't want the users to change their way of working...
They are used to:
- press F1 to inqury
- press F2 to insert
- press F3 to update
- press F4 to delete
- press F5 to release
....

As you can see I need to intercept the function keys and to
change their functionality.

--------------------------------------------

Back to the topic...

This is what I've done:

/*
* Intercept all the 'function keys' and invokes the related submit input
* (if one exists). This method must be invoked when a "keydown" event occurs
*/
function interceptKeyDown(e) {

keyCode = e.keyCode;

if( keyCode >= asciiF1 && keyCode <= asciiF12 ||
keyCode >= asciiPgUp && keyCode <= asciiHome ) {

e.keyCode = 505;
clickButton( keyCode );
return false;
}
}
attachEventListener(document,"keydown",interceptKe yDown,true);

/*
* Intercept all the 'function keys' and invokes the related submit input
* (if one exists). This method must be invoked when a "keypress" event occurs
*/
function interceptKeyPress(e) {[indent]
if( !e ) {

if( window.event ) e = window.event;
else return;
}

//NS 4, NS 6+, Mozilla 0.9+, Opera
if( typeof( e.which ) == 'number' ) {

var keyCode = e.keyCode ? e.keyCode : e.which ? e.which : void 0;

if(e.charCode == null || e.charCode == 0 ){

if( keyCode >= asciiF1 && keyCode <= asciiF12 ||
keyCode >= asciiPgUp && keyCode <= asciiHome ) {

e.stopPropagation();
e.preventDefault();
clickButton( keyCode );
}
}
}
}
attachEventListener(document,"keypress",interceptK eyPress,true);


/*
* According to the type of browser, adds a new event listener to
* the specified object ,for the requested event, binded to the
* specific function.
*/
function attachEventListener( obj, type, func, capture ) {

if(window.addEventListener){ // Mozilla, Netscape, Firefox

obj.addEventListener( type, func, capture );
} else { // IE

obj.attachEvent( 'on' + type, func );
}
}


the function clickButton( keyCode ) changes according to your specifications
