JS window.event
Does anyone know why the following works in IE but not NS ?

Code:
function check_key() {
alert(window.event.keyCode);
if (window.event.keyCode == 13) {
return false;
}
}

Im using:

<body onkeypress="return check_key();">

Hmm one day I'll stop answering my own questions :)

>>
Internet Explorer and Netscape have different implementations for the KeyPress event. One difference is in how to retrieve the character that was pressed. IE uses event.keyCode and Netscape uses event.which. Also, Netscape only recognizes the event object if it is passed in from the text field's event handler. IE can use the passed-in event or can reference window.event without it being passed in.

Hmm still doesn't seem to work though.

With IE if I do:

Code:
if (window.event.keyCode == 13) {
return false;
}

....it works fine, but with NS if I do:

Code:
if (mykey == 13) {
return false;
}

....it doesnt work and the frame with the JS code in reloads to the wrong page when it shouldn't reload at all.

If I do alert(mykey) it shows 13 which is right :(

Oh thanks...that might be whats wrong with NS then. I don't get any errors with 6.2...or at least I don't see any alerts.

I'll fix those up (although Im not sure whats causing them as IE doesn't give errors)...guess there is a difference in how NS interprets the code....

I don't understand those errors.

rooms and send are both defined as form names.

Unsure

Woohooo....persistance paid off :)

I got my thinking cap on and managed to solve it. Seems to be working now in Netscape and IE.

I just have one weird error left:

Error: redeclaration of const kIOServiceProgID
Source File: chrome://communicator/content/utilityOverlay.js
Line: 1

However it doesnt seem to affect anything.

Paul I now get this with mie in your top left frame after log in-
An error occured processing your request:

Can't use an undefined value as a HASH reference at admin/Library/Chat/Handle.pm line 229.

Caller: Chat::Handle, admin/Library/Chat/Handle.pm, 229

and this is the js error from netscape -
JavaScript Error:
http://213.106.15.150/cgi-bin/chat2/wochat.cgi?do=load_frames&frame=frameset_right&sessionid=SHs2kViksjSjlhfTBMJBbOol8KETFlIy1aU4jQ7faSd4KsmTYw&Room_Name=Default,

HI,

If you log out and back in it should fix that perl error (I'll fix it though). Thanks for the link too.

I just don't get NS's problem. I have two frames:

high and low

Within high I have left and right.

In IE to reference something in another frame (say high+left) I can just do:

top.high.left.form_name.form_field.value

....with NS it just tells me top.high.left has no properties....grrrrr

Hmm where did you get that error?

It should be post.Message not sender.Message which is causing the error but I can't find it.

Hmm went out for a few holes of golf but didn't exactly come back refreshed..ah well :)

Almost everything is fixed now apart from the fact that with NS the bottom frame reloads if you try to submit your message by hitting return...grrr.

Using event.which and returning false doesn't seem to stop it. I've tried adding return false; in 100 different places and nothing works with NS....IE not a problem Pirate
