As promised a few days ago (by Jordi mainly), here is the code I can
contribute to the javascript extension file(tm):
I copy the text into the message, as I personnaly HATE attachments for this
kind of short text. It will also be easyier to comment/modify/reply.
However, if you (i.e. people on the list) prefer it sent as attachment,
just tell me.
Please also note that the comments used are NOT easily parsable/strippable,
as proposed earlyier on the list, by using '/*---' or the like one-line
comments. I'll write in another post maybe some clues about comment
stripping. The comments given can also be much reworked, if they sound too
'French' or 'Dutch', or simply are incomplete
Also sorry fot the tabbing, but I usually use small tabs, 3 or 4 in my files...
Not all of the stuff is "own made", some ((un)shift, push, pop, splice)
comes from webreference.com (see previous posting from Joachim Lundgren,
msg ref [EMAIL PROTECTED]), The trim string
methods/function are mostly from him too.

For the interested, among the few ones that read this post till the end, I
also can contribute a fonction that parses an url and returns a table
comparable to what PHP brings in the HTTP_GET_VARS.
I also have some functions (and help) to handle "global vars", i.e. get/set
for variables that can be used in a framed site, thus with different documents.
If there is some interest, mail me, as these kind of functions are not
really useful for the DynAPI (I think, except maybe for server-side
interactivity (sorry I haven'r read ALL the posts about it))
