This is a repost (previous one seems to have gotten lost :)
Once you split up parts of the API for every browser (that could eventually
include Opera, and other flavours) it means that people will start focusing
on a single browser because that's the browser they'll be using. Ofcourse
this is already being done on a smaller scale (Dan's main focus seems to be
Netscape, and my focus is more IE5+) but at this point because of the code
being one , we know that what ever we do should also work Netscape.. once
you split things up I think this "awareness" will disappear and people will
just enhance the code for that single browser and let someone else worry
about the other browsers files.
"All this is done only to define two basic paisr of vars. Terrible. And
impossible just to skip the nn stuff, becoause it's not clear, what refers
to nn but only what is not for ie. I have to go through it and to
learn the"
that's correct, just two basic pairs of vars, so you want to split all code
up for simple things like these? And the fact that you have to go thru it
and learn the differences is exactly my point, if you have the chance to
only do your coding for IE, you will forget about NS and this might cause
you to implement things in IE that are not possible in NS. Ofcourse this
means we're holding back one browser because of the incompatibilities with
the other, but that's the problem with cross-browser coding, and if you need
that extra functionality you should added it in your own code, not in the
general API.
The problem with speed that everybody talks about is not such a big issue,
we're not developing for 386 or 486 machines anymore, Pentium machines don't
take 2 or 3 clock-cycles to do a simple IF statement. Besides the IF
statements are only called at initialisation and when changing styles, the
main bottle-neck is not the IF statement but the time it takes browsers to
redo the style sheet (and rerender things). This is just a browser problem,
not a code problem.
And ofcourse size isn't such a big issue neither, seeing that most of the
differences (I know, not all) are done on single lines as you pointed out:
is.ie?e.x+document.body.scrollLeft:e.pageX-window.pageXOffset
this will only be a few bytes difference once you split it up:
e.x+document.body.scrollLeft
so maybe you save some bytes with the split but you have to include all
files multiple times and maintain all files multiple times for your site to
look good on all browsers.
apologies for the long post :)
