Hi everybody!
I have a question regarding IE. I have a client using a script (which I can not change as it is an affiliate program's script that I can not control) that creates a variable called "event" and assigns a number to it. This is the line:
Later on, there is another script that should use window.event, but... it does not work, because window.event gets rewritten by the previous script and it stays filled by the number!!!
In your opinion, is there a way to empty the "event" variable, and restore it to its original state, including srcElement?
I have tried setting: - event = null;
-
event = window.event
-
This resulted in having window.event value back to null, and its type as object (as it should be). But srcElement will not work :-(
Any suggestions? Thanks in advance!

null always returns 'object' from typeof, because it is not 'undefined'.
IE doesn't give you access to a constructor or prototype for event.
I never thought of trying to assign event to something,
but I gave it a whirl in IE7:
window.event=33
and got a 'member not found' error- but event was untouched.
I don't have any old IE's around, so I don't know what they may do.
I can't imagine the purpose of the 'affiliate' script, unless it is to discourage event handling in IE.
unfortunately not... it is just a variable they arbitrarily called "event" without thinking about it :-(
I'll make some tests... thanks anyway!
cheers

Interesting. I don't know why it's not made read-only. This affects IE7 too.
Is there no possibility of changing the script?

unfortunately, that script is not under my control... and although it looks silly calling a variable "event", IE is absolutely more silly by allowing that to rewrite window.event!
Anyway, for the moment, changing the script looks like the only viable solution...
thanks everybody for your help! This just looks like another IE "feature" we will have to remember :)

True, I'll have to add it to the list of bugs. Thanks for bringing this up.

Hi,
the restoration of a dump stops at the line above. The dump was created with
pgsql 7.3.2 and I need to pump it into a 7.4.3 one. Should anybody tell me
what the problem can be and how I can solve it.
(There are double apostophes many times in the string - is it normal???
Besides of the field separator of course...)
Many thanks,

Every so often, I'm asked to help people recover data from tables that

The complications related to restoring data are a problem. The SAS users
are laughing because they can (to a certain extend) easily go back to an
earlier SAS table by simply starting dsm. Of course, a flat file table is
different than a relational table; but still, the trouble related to

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
