Just an update, I found that Safari has a nice resource tracking
feature on it that helps with evaluating performance of your website
and all the elements in it. separately even.
You can right click on a site and in the menu you should have
"inspect element". A bottom window will raise up with all the info
you need. Well.. almost all.
You can track load times, view scripts and css and many other things.
Hope that helps someone like it did me.
Best,
Karl

Karl, I'm not sure how to benchmark memory in AS 2. I think that
what you
might want to benchmark here is cpu performance, anyway.
In this particular case, I don't think you can benchmark much, though.
Basically, all performance benchmarks I've seen are based on
getTimer (two
simple calls to getTimer, one before running the code you're
interested in,
and one after; the difference is very roughly how much your code
took to
run; there are more sophisticated suites (like Grant Skinner's),
but to my
knowledge, all are based on the same principle).
The problem here is that what seems to be taking too long is an
internal
mechanism of the player (managing and dispatching onChanged, for
instance).
Can't think of a way of timing that off the top of my head.
If one the methods runs your fan wild and the other one doesn't,
though, you
have a clear winner already!

On that note, what would be a good way to get a benchmark for this?
Any pointers?

Ahh.. let me try that.
I am sure you are correct.
That way it only checks to see if that textField is changing when
focus is
on it.
And being that onChanged was less memory intensive than onEnterFrame
that makes sense. But my tests are not finite.
I do not have a benchmark result or anything stating
how much memory my swf is using while in the browser.
But it would seem the onSetFocus/onKillFocus keeps any extra
memory from
being used in either case.
Thanks again Juan.

Not really. In theory, onChanged should be less intensive, I

from your description it seems it isn't, so go figure...
I'd go with the onSetFocus / onKillFocus then, but I'd do
another test,
just
out of curiosity. Instead of setting an enterframe when you get
focus and
nulling it when focus is lost, what happens is you use the
onChanged
event
instead?
I mean, something like:
textbox.onSetFocus = function() {
textbox.onChanged = etc...;
};
textbox.onKillFocus = function() {
textbox.onChanged = null;
}

Hi Juan,
Interesting enough, it seems your solution also runs my fan a
bit wild
too.
Not as bad, I'd say about half as much.
I know its the form because I have tested many times. Every
time I close
the browser window that has the form, my fan slows to a stop
almost
immediately.
I chose the onFocus mainly because I knew that it was the
onEnterFrame
that
was taking up memory, so I wanted it to fire only when someone was
typing.
It looks like my suggestion does just that. The fan never kicks
on.
My purpose for this is to set up a flash site that takes little
to no
memory usage.
Am I right in assuming that this is memory usage by the code
that makes
my
fan kick in.
I've been nulling any onEnterFrames, removing listeners, etc.
Any thoughts as to why the onChanged eats memory too?
TIA

It seems like you don't really need to bother about gaining or
losing
focus
here. Just listening to the change event will do the job and
you could
remove the enter_frame.
commentxt_mc.onChanged = function(tf:TextField):Void {
var numChar:Number = 650 - tf.length;
if (numChar == 0) {
maxChar = "Max Characters Reached";
} else {
maxChar = "Max Char: " + numChar.toString(); //Have
another
text box with the var maxChar to display the results while
typing.
}
};
The equivalent in AS 3.0 is very similar, though a bit more
verbose (as
usual!):
commentxt_mc.addEventListener(Event.CHANGE,handleTextChange);
function handleTextChange(e:Event):void {
var tf:TextField = e.target as TextField;
if(!tf) {
return;
}
var numChar:Number = 650 - tf.length;
var maxChar:String = "";
if (numChar == 0) {
maxChar = "Max Characters Reached";
} else {
maxChar = "Max Char: " + numChar.toString(); //Have another
text box
with
the var maxChar to display the results while typing.
}
}

PERFECTO!
Thanks Amol,
For anyone who might want this. I have made a script that
will read
the
length of a text field and display the number of characters
left while
someone was typing.
The reason for the code I was seeking with this request was
because
the
code previously would eat up a lot of memory. It made my
computer fan
run
wild if the form sat in my browser.
Now it does not thanks to Amol. :))
Here is the code competed. Again, it is as2, but would love
to see an
as3
conversion.
I might get to that later, but welcome any comers.
//commentxt_mc is the textfield name, 650 is the number of
characters
allowed. You will also want to set the text box max
characters to this
when
creating your text box.
var numChar;
commentxt_mc.onSetFocus = function() {
onEnterFrame = function() {
numChar = 650 - commentxt_mc.length;
if (numChar == 0) {
maxChar = "Max Characters Reached";
} else {
maxChar = "Max Char: " + numChar.toString(); //Have
another
text box with the var maxChar to display the results while
typing.
}
}
};
commentxt_mc.onKillFocus = function() {
onEnterFrame = null;
};
Best,
Karl

Subject: [Flashcoders] Text area focus
Hello,
I have a text box or area on a form that I would like to
know when a
user has put the cursor in it or not.
Wither it has focus or not. I am working in AS2. Please
don't grit
your
teeth too much :-)
For some reason I am not able to get the focus of my text
area.
Anyone have this code in their scrap files?.. lol
TIA
