Adding qawanted keyword - is there a test account (i.e. TestID and password)
we can use at this site? I do not have a Yahoo account, and can't access
the above URL - thanks.

[e-mail]: are there any errors in the Java Console as well?

Reassigning to OJI for a look, as this gaming site is Java-intensive, 
and I believe someone in OJI may have an appropriate UserID, password
to look at this site I can't access it.

Compare these other OJI bugs filed against this site: 


                         bug 84457
                         bug 88906

Please send back if this actually turns out to be JS Engine - thanks.

No.  There are no java console errors.  In fact the games work fine if started
by direct links.  (I had some direct links in my history from running 0.9.4)

Comment 7

[shrirang khanzode]

works fine on my NT with 1.3.1 jre and today's branch build.

Comment 8

[Igor Nekrestyanov]

I was able to play anagrams (on Linux).
Did not see nor javascript erros neither java errors.

Test login is user: oji_test, password: test_oji

Comment 9

I believe the problem has something to do with the javascript code for the
screen size selector found in the card games "room" selection pages.  I notice
on 0.9.4 (which works) that the screen size box is pre-filled with 800x600,
while on the daily builds (that don't work) the screen size box is empty and
cannot be changed.

Reassign to Joe as I'm leaving the role of OJI module owner.

Ressign to Joe Chou, as I am no longer working officially on OJI.

Attachment: Javascript-generated listbox testcase

Comment 13

[Darren Stone]

games.yahoo.com uses javascript to generate the options in the "screen size:"
listbox.  Mozilla is failing to handle this correctly; I've attached a testcase.

[Phil Schwartau]

This sounds like a DOM problem; reassigning there for analysis.
Compare bug 99859, "mobile.yahoo.com - phone model menu not functional"

This bug exists in Mozilla 0.9.5 (Linux) as well

Comment 19

[Phil Schwartau]

The reported error in the JavaScript Console:

      "Error: res.options[res.selectedIndex] has no properties"

comes from this part of the HTML source at games.yahoo.com:


<form name=resolution action="/" method=post>

<select name="res">
<script language="Javascript">
 document.writeln('<option value="small"'+ scrSize("s") + '> 640x480' +
                  '<option value="large"'+ scrSize("m") + '> 800x600');
</script>
</select>

</form>


At the games.yahoo.com site, you are unable to choose any option in 
the "Screen Size" selectbox (to the right of "Select a Room to play in"). 
You can SEE the '640x480', '800x600', but you can't select anything.


If you type this in the URL bar

            javascript: alert(document.resolution.res[0])


you get:           Mozilla ---> null
                   NN4.7   ---> [object Option]
                   IE4.7   ---> [object]


The problem, caused by a dynamically-populated <SELECT>,  
is well-illustrated in  Darren's reduced testcase above.

Comment 20

[Phil Schwartau]

The error in the JavaScript Console gets triggered by this function:

function lobbyopen(name)
{
 var sel = document.entergame.identity;
 var res = document.resolution.res;
 var dms;
 var small;

 if (res.options[res.selectedIndex].value == "small")  <<<<<<----- ERRORS HERE
 {
  dms = "height=400,width=620,";
  small = "&small=yes";
 }
 else
 {
  dms = "height=520,width=786,";
 }

  small = "";
}


Again, this is caused by the dynamic population of the <SELECT> 
named "res" above. This problem has been reported in another bug,
which I'd like to dupe this one against. Even though it has a 
later bug number, it zeroes in on the specific issue -
