From the information given by the OP, they were equally helpless.

Unfortunately this group can be a little.. old school.

No. It's just that this group is about JavaScript (and its other brand
names) and not about some libraries written in JS. Just as PHP NGs are
about PHP and not some third party applications written in PHP. And just
as C/C++ NGs are not dealing with the problems of applications written
in these languages. You get the idea?

they're all but blind to the benefits that jQuery (and
the other hated libraries) bring to real world developers.

Makes one wonder why all those problems (I suppose I should say
"questions" ) of such "real world developers" come from...

Try the section about how to post properly; it will lead to everything
else.

Thomas, You are turning into a bit of a troll. Could you say the same
substance but in a more polite fashon please; as its degrading the list.

Yeah, I never liked jQuery from the start, bumping into $("yyy"). when
reading code was not a very nice experience.

There's another library I have came accross that seems to do the same as
jQuery but seems alot lighterweight and have not heard it mentioned on clj.

http://www.domassistant.com/

Have not used it, but it has four figure version numbers and is up to
2.7.1.1 so it _may_ be a good library.

Anyone checked it out ?

since I just joined this group and haven't attempted to search the
archives.)

I have a page under construction which uses jQuery and is fairly
massive. When I run it locally under Firefox, everything works fine,
but when I run it on the host site, I frequently run into difficulties
of the following type. I have a $(document).rea dy() function that
references variables and elements defined either in other JS scripts
(inline), or in the HTML. Sometimes, but not always, a reference to
one of these variables or elements resolves to a null pointer, which
aborts the execution of my $(document).rea dy() function and causes FF
to get hung up in the wrong place. For example, I have a JS variable
called 'calimg', which is supposed to be a string containing the URL
of an image file, and if I look at the source, that is how it is
defined, in a script that is placed before the script containing the $
(document).read y() function. But often, Firebug reports that the
variable 'calimg' is not defined when the $(document).rea dy() function
runs. What is causing this, and what can I do about it?

Yeah, sorry but you have to realize that if everyone is reading your
question thet is X amount of time times Y readers, these whole threads are a
waste of time and should be avoided, best for both sides not to start them
in the first place.

As they say a library is no substitute for knowing whats going on with "bare
metal javascript".

If there are issues with jQuery then take them to one of the jQuery
disscussion lists :-

http://docs.jquery.com/Discussion

comp.lang.javas cript is really for Javascript language issues, this is not
alt.lang.javasc ript and maybe there should really be one.

Look at the UseNet groups title "comp.lang.java script" this sort of thing
would not be tollerated on comp.lang.c or c++. Maybe we need a
comp.lang.javas cript.misc or alt.javascript group for this sort of thing ?

Also for fun you can read up on the various personalities here:
http://redwing.hutman.net/~mreed/war...ssrebutter.htm

No its happening because the 'comp.lang' group is not being used properly.

Anyone can make fun and add a donations page that does not even render
properly.

involve the possession of the technical understanding that would
result in the reader seeing the many faults and nonsenses in the book
and so dismissing it out of hand as a learning source.

Personally I use a bar magnet and a magnifying glass. Saves amazing

Well, there is certainly one valuable thing that can be learned from this
book: how not to write one ;-)

Oh, yes, the magnifying glass changed my life. But what's the magnet
for ?

Dunno...

line 6:
var isIE = /*@cc_on!@*/false;

line 1330:
if (/KHTML|WebKit|iC ab/i.test(navigato r.userAgent)) {
DOMLoadTimer = setInterval(fun ction () {
if (/loaded|complete/i.test(document .readyState)) {
DOMHasLoaded();
clearInterval(D OMLoadTimer);
}
}, 10);
}


And why would one want to do something like that:

window.addEvent = this.addEvent;
window.removeEv ent = this.removeEven t;

if you had prudently read the newsgroup before posting, you would have

Hehe. Yeah, my point was that there are serious experts in this forum,
but few programmers - even good ones - have the time/inclination/
ability to delve into the inner workings of JS (and even fewer get to
the point where they seem to be able to quote the spec at will!).

And hey, an accessible library like jQuery is [hopefully] a good entry
point for someone who will later learn *ahem* real JS.

Meanwhile, I'm fixing basic PHP/SQL injection issues because there are
plenty of php hobbyists who refuse to use frameworks because they
don't understand how they work (so they must be bad). It's basically
the reverse scenario - except that as far as I can see, it is better
to have someone bumbling around within a fixed set of functionality
than to be let loose to create havok in ways they don't understand.

That's what you fail to understand. It isn't. There is no argument
for it. Search the group. Thanks.

I guess it does that because shortly afterward it does:

var pushAll = function (set1, set2) {
for (var j=0, jL=set2.length; j<jL; j++) {
set1.push(set2[j]);
}
return set1;
};
if (isIE) {
pushAll = function (set1, set2) {
if (set2.slice) {
return set1.concat(set 2);
}
for (var i=0, iL=set2.length; i<iL; i++) {
set1[set1.length] = set2[i];
}
return set1;
};
}

[...]

And why would one want to do something like that:

Because the author(s) do no know how to implement effective feature
detection?

How about:

var HTMLArray = function () {
// Constructor
};

....

if (isIE) {
HTMLArray = Array;
}
HTMLArray.proto type = [];
HTMLArray.proto type.each = function (functionCall) {


Which extends Array.prototype in IE with an each method, but in other
browsers extends a generic array object.
