"Some authors said (and this was where I got confused) that the
closure has access to the variables of the outer function. This is
sort of true. Really it has access to the variable's names and values
at the moment the closure is created."
This isn't clear enough... a bit messy.
An inner function that survives keeps working **exactly*as*it*did**

"The execution context contains names and values of, among others,
variables, parameters and inner functions. When outer() returns a
function it also returns its execution context at the time of the
return."
The idea is something like:
0.- Upon entering a function, a new execution context is created for

FF 1.5 really shouldn't be used anymore, except for compatibility
testing. I would understand version 2.x (some people can't run 3.x
because of missing libraries), but 1.5 is ancient.
After reading that bug report, and the specs, it looks like that's the
correct and expected behavior. Inconvenient, maybe, but at least it's

Declare an outer function, including any necessary parameters and
data. Declare an inner function. Have the outer function return the
inner function.
function outer([params]) {
// vars declared here
var closure = function([params]) { /* code here */ }
return closure;
}

Where does he say that?
You're quoting him out of context; JSON wouldn't be possible if nested
curlies weren't allowed. Just a guess, but he was probably talking about
the absence of (traditional*) block scope in JavaScript, and was
suggesting that unnecessary {} blocks shouldn't be used, in order to

The trouble with you (well one of the troubles so far) is that you are
playing games with your headers. Combine that with an obviously OT
solicitation and there you are.
LOL. I do agree that Dynamic Drive is so BTDT (bookmarked that,
deleted that?) Nobody ever found anything good on *that* site.

Why not? It is a perfectly reasonable way to get transparent borders
in IE6 (provided you wrap the rules in conditional comments.)
So, add and remove the rule (or sheet) as needed. What's the problem?

JFYI: Firefox 3.0.3 is the currently stable version. The 1.5 branch reached
its end of life on 2007-05-30 CE with the release of Firefox 1.5.0.12, and
2.0 will in mid of 2008-12 CE.

IIRC, Richard wrote the article in question. I think it is far more
helpful than this new one, even for beginners. Certainly it is the
first article on closures that I ever read and it really opened my
eyes to the possibilities (and pitfalls.)

JS/DHTML Grid Product - Favorites?

shor...@gmail.com (ashore) — Sat, 11 Oct 2008 17:24:46 UT

For possible inclusion in an Open Source application I'm writing with
PHP/MySQL server-side, I can use a decent ajax-aware grid component.
I see several good-looking ones at freshmeat, but I thought I'd look
for yr experiences for some help in selecting one.
Nothing unusual in terms of requirements; common datatypes, etc.

Those are more or less the same, despite the different JS engines

I do. So do a lot of people around here. Hence...
Lack of an incident is no real comfort, but if it is just a
