I'm using microsoft i.e. explorer 5.5 with win95
at an offsite location and it lets me load pages
like pbabble admin, but it notes at the bottom that there are "errors on page".When I try loading things at home with i.e.
explorer 5.5 with win98, I get the shaft whenever
I try to load any page. I get a java script error
which is basically telling me that some ptr or
id for a cookie called babbletime or babbleprev
or something is NULL because the cookie is not
located anywhere and you don't check for a null
ptr. Tsk, Tsk. This started a few days ago. I was
able to look at the java script in visual c++ when
i.e. explorer hit the error (it asked me if I wanted to debug it, so I did although I don't no jack cheese about java).I sent a message using the home page "feedback" with a description of the error and my email, and this problem has not been addressed. I can't read any feedback in the threads (only the top part right before the threads appears in both my netscape and explorer windows).
Can we get this fixed? Why doesn't my i.e. exlorer
at home go past the error, but this computer offsite does? Hmmm..Thanks,
John

This same offsite machine has Netscape communicator vr. 4.7 and it does the same thing
as mine at home. That is it quickly shows a
java script error message (flashes too quickly to
read), and then it tries to load the rest of the
admin page past the header, but it never displays
the threads.John

http://www.dr-bob.org/babble/admin/20020510/msgs/5656.html
combTime might be null, but why would that be a problem? Could someone else take a look?
In the meantime, maybe just try this:

And then you dereference a NULL object????
idx = combTime.indexOf(":") <--- combTime = NULL
Also, it does pass under my win98 but I get a
debug trap with every java error and I am prompted
as to whether or not I want to debug it (If I
click no on a million follow up errors the page
appears as it did on the other computer). I don't
get this on the other machine. Maybe because I
have a lot of software development tools on my
machine, some setting somewhere is causing the
debug traps.Every where else in your script you check to see
if a cookie returns NULL. But you don't do this
for babbleadmintime.Also, I don't care for the way the password cookie
has the password in plain ASCII if you load the file. Maybe there is a way you could encrypt this and deencrypt it locally so that wrong-doers don't walk off with our passwords.John

idx = combTime.indexOf(":")
The error being:
-- combTime is NULL or not an object --
My debugger shows combTime = NULL

Maybe there is a way you could encrypt this and deencrypt it locally so that wrong-doers don't walk off with our passwords.I don't care for it, either, and it's on my list of things to do. In the meantime, there's a way to erase your cookies if you're concerned about wrong-doers:
http://www.dr-bob.org/cgi-bin/pb/extras.pl
But maybe you can also help me with this:
1. Is there a way to encrypt in Javascript?
2. Even if cookies were encrypted, couldn't a wrong-doer still just walk off with them (and use them later) in that form?
3. Even if cookies were encrypted, the form would still need to be able to accept unencrypted passwords, since the poster might have erased their cookies or just not have cookies turned on. How would the form be able to do both?

Thanks for the fixes. It runs smoothly both under Netscape and Explorer with no Errors.I don't know much about Java, so I don't have good answers to your questions.
There must be a way to do the password encryption though I would think, as this would be a substantial security issue for something like online banking, etc. I don't think it could be done using a Java script running on a client though, as a hacker can break into and read the Java code like I unintentionally did.
Gee I hope the online banking, brokers, etc with
autocomplete aren't exposing passwords as such.Regards,
John
