[Flashcoders] Identifier expected
Hi list...
Simple question -- why doesn't the 2nd line work? The identifier
expected error is traced at compile time.
Thanks,
- Michael M.
function createObj():Void {
this._data = new Object();
this._data["a"] = {"1":new Number(0), "2":new Number(0), "3":new
Number(0)};

Re: [Flashcoders] Identifier expected
As you have discovered you are not able to use numbers as keys in line
objects.
Trying to do what you do will however not change this. Only way to do
what you want would be to insert the indexes manually:
function createObj():Void {
this._data = new Object();
this._data["a"] = new Object();
this._data["a"][1] = new Number(0)
}

RE: [Flashcoders] Identifier expected
2 issues:
1) identifiers are an expression not a string ie a:"hey" vs "a":"hey". The
later will not work
2) You can not use a number as identifier in this case. The compiler catches
it and throws an error. However, you can hack it using this[1] = "hello
world"; trace(this[1]); but then you can use {:} type syntax.

That's not true.
Just wrote this and it works fine.
a = {};
a["a"] = {};
a["a"][1] = new Number(5);
trace(a["a"][1]);
-- 5
Works for me. You must be doing something else wrong.
I'm not sure why you're using new Number(). I don't think I've ever
used that. Ever.

RE: [Flashcoders] Identifier expected
The second line does not work because you are evaluating a string to try
to resolve it to a property of the object, (which you are hoping is a
sub-object) that does not exist yet. In other words,
this._data.a
the .a in the above statement has not been declared or identified as an
object, and thus this._data["a"] resolves to nothing.

RE: [Flashcoders] Identifier expected
Thanks Jason. I see what you're saying. So I inited an object and then
define it, but the below still errors. I was just hoping to be able to
define my object with only one line of code.
private function createData():Void {
this._data = new Object();
this._data["a"] = new Object();
this._data["a"] = {"t1":0, "t2":0};
}
I was using new Number for a reason, but it's not critical I suppose.
Thanks Steven.

RE: [Flashcoders] Identifier expected
That's because you're still not refrencing an object that exists:
>>this._data["a"] = new Object();
You're saying, Hey, _data, make your "a" property an object. But Flash
is saying, hold on cowboy, I don't see any property of _data called "a".
So instead:
private function createData():Void {
this._data = new Object();
this._data.a = new Object();
this._data.a = {"t1":0, "t2":0};
}
Or use the one-liner Steve just posted, which is intead, an explicit
declaration. I use that one commonly.

Re: [Flashcoders] Identifier expected
Uh, Jason.
There's nothing wrong with saying:
var data:Object=new Object();
data['a']="something";
Try it.

RE: [Flashcoders] Identifier expected
Right, But "a" is not an object. If you follow the thread, you will
see that's' what he's trying to do. There IS something wrong with:
private function createData():Void {
this._data = new Object();
this._data["a"] = new Object();
this._data["a"] = {"t1":0, "t2":0};
}
createData()
trace(this._data.a)

OK, I see, so then curious why this script returns compiler errors:
function createData():Void {
this._data = new Object();
this._data["a"] = new Object();
this._data["a"] = {"t1":0, "t2":0};
}
createData()
trace(this._data.a)
Seems to be something wrong with that.

You can tell that Michael is mostly a Director user, can't you? :)
In Lingo, we have property lists, which can use strings or numbers as
properties. So ["1":0, "2":0, "3":0] would be a valid Lingo propList, but
ActionScript isn't quite the same, as others have explained. My guess is
that you're trying to match an AS list to a Lingo list without worrying
about the fact that Lingo lists are 1-based rather than 0-based. A simpler
solution would be to use a Flash array where the first element is 0.

Because when using the object initializer operator, you cannot use
strings as identifiers (similarly to variable declaration).
In the above script the this._data["a"] = new Object(); line is simply
not necessary, and the right syntax of the last one is:
this._data["a"] = {t1:0, t2:0};
or even better:
this._data.a = {t1:0, t2:0};

I understand what you're saying, but in context of what he's trying to do
(inline object declaration), explain the compiler error on this code:
function createData():Void {
this._data = new Object();
this._data["a"] = {"t1":0, "t2":0};
trace(this._data.a.t1)
}
createData();
So instead, this is ugly, but works:
function createData():Void {
this._data = new Object();
this._data["a"] = new Object();
this._data["a"].t1 = 0
this._data["a"].t2 = 0
trace(this._data.a.t1)
}
createData();

Re: SPAM-LOW: [Flashcoders] Identifier expected
Wow, a lot of misinformation here gents.
this._data["a"] = {"1":new Number(0), "2":new Number(0), "3":new
Number(0)};
When creating a new object using this syntax the property names are
considered strings. Adding the quotes is what is causing the issue. If you
remove the quotes the compiler will still complain because you can start a
property value with a number, unless you use the [] syntax for creating a
property. In that case you can use anything you want, even non-printable
characters.
"

That's not true.
Just wrote this and it works fine.
a = {};
a["a"] = {};
a["a"][1] = new Number(5);
trace(a["a"][1]);
"
The quote was "in line objects", so the statement was true. What you did
was take the "in line objects" and represent it in a different manner.
"The second line does not work because you are evaluating a string to try
to resolve it to a property of the object, (which you are hoping is a
sub-object) that does not exist yet."
No, he wasn't.
this._data = new Object(); // Fine
this._data["a"] = {}; // Still fine
this._data was created, then this._data.a is created afterwards using the
{} syntax instead of new Object().
That's why this still produces errors:
"
private function createData():Void {
this._data = new Object();
this._data["a"] = new Object();
this._data["a"] = {"t1":0, "t2":0};
}
"
If you MUST have numbers as the property values, use Chris Benjaminsen's
version:
function createObj():Void {
this._data = new Object();
this._data["a"] = new Object();
this._data["a"][1] = new Number(0)
...
}

Hi list...
Simple question -- why doesn't the 2nd line work? The identifier
expected error is traced at compile time.
Thanks,

function createObj():Void {
this._data = new Object();
this._data["a"] = {"1":new Number(0), "2":new Number(0), "3":new

Stop using new Object() and use {};
:)
I'm not experiencing the same issue you're having Jason. Not sure why.

RE: Re[2]: [Flashcoders] Identifier expected
I didn't even notice that in the script before - should have been obvious.
Sorry for the noise.

Re: Re[2]: [Flashcoders] Identifier expected
It's nothing to do with the 'a', it's the 't1' and such in quotes
that's the issue.
>>MJ> function createData():Void {
>>MJ> this._data = new Object();
>>MJ> this._data["a"] = new Object();
>>MJ> this._data["a"] = {"t1":0, "t2":0}; } // The quotes in this line are
wrong
Won't compile.
This will:
>>MJ> function createData():Void {
>>MJ> this._data = new Object();
>>MJ> this._data["a"] = new Object(); // Note this line is totally
pointless
>>MJ> this._data["a"] = {t1:0, t2:0}; } // This line is now correct
Incidentally, the third line is completely redundant. This is correct:
>>MJ> function createData():Void {
>>MJ> this._data = new Object();
>>MJ> this._data["a"] = {t1:0, t2:0}; }
Because new Object() and {} are synonymous.
var data:Object=new Object();
data['a']={t1:0,t2:0};
is exactly equal to:
var data:Object=new Object();
data['a']=new Object();
data['a']['t1']=0;
data['a']['t2']=0;
which is also equal to:
var data:Object={a:{t1:0,t2:0}};
or, because Object is dynamic
var data:Object=new Object();
data.a=new Object();
data.a.t1=0;
data.a.'t2=0;
To recap - the error was putting quotes in the key names.
HTH,
Ian

var data:Object=new Object(); data.a=new Object(); data.a.t1=0; data.a.'t2=0; Whoops - a stupid stray quote in the last line.
