(Firefox :: General, defect)

Description

[Benjamin W. Slivka]

User-Agent:       Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322; .NET CLR 2.0.50215)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8) Gecko/20051111 Firefox/1.5

I wrote this Tic Tac Toe program using client-side DHTML + JavaScript for IE in 2002, and it works perfectly.  Click on a square to put your X, and browser plays O.  But when I run this under FireFox, it doesn't work.

I have several other programs that use similar "technology", and they all also do not work under FireFox (but do with IE).

Reproducible: Always

Steps to Reproduce:
1. Visit the URL above (ttt.htm)
2. Click on one of the Tic Tac Toe squares
3. An X should appear, but instead nothing happens.

Actual Results:  
As above, works perfectly in IE (I'm running 6.0, but these were developed in 2002 against IE 5.0).

Expected Results:  
See above.

I wanted to file this against the Dynamic HTML engine and/or the JavaScript engine, but didn't see either of those called out as components.

I assume this is a general compatibility issue for FireFox vs. IE.

window.event is IE-only (see bug 54341) and you're referencing by name/ID in the global scope (document.getElementById() should be used instead).

document.all is also IE-only and again use document.getElementById() instead.
