Ok, I don't have the bug anymore, but my script is no longer working
(and I know why so at least I know where to look)
For information purposes all I did was changed this line
code += init.join(';')+';';
to this line and the error message went away
for (i = 0; i < jsl-1; i++) code += init[i]+';';
only issue is, I use an alert to display code afterward and this is
what happens:
1. When the first line is used the alert will display the code to eval
perfectly, but the error message will be there and the code doesn't
work
2. When the second line is used the alert is blank, and of course
there is no error because it eval('');
Note the jsl-1 is temporary it's just in my example need the ui core
so removed 1 out of the new length to avoid undefined being inserted
in the code, at start I thought that it was the reason for the alert
being blank, but it isn't)
Both lines of code works perfectly as expected in FF3 (haven't tried 2
yet) and Safari 4 (accordion bit jerky on it like on ie)
http://codeserenity.com/jquery/scriptless/demo4.html - for demo - code
same as above but 4, working on it so might not always work :p
So my guess is join() and += in IE don't work the same. I don't know
why the code variable becomes blank tho. The only silly thing I think
of is maybe the return of eval is ''. My only worry is that if I can
make it not blank I'll just get the error again.
Oh, and only tried on IE7 so far as well for the bug, not IE6 or IE8.
