FAO Robert: Why won't this code work part 2

[FayeC]

Ok....I made the appropriate additions to the spaces commented and this is
what I got now:

currentDate = new Date;
today =
currentDate.get Date()+"/"+currentDate.g etMonth()+"/"+currentDate.g etYear();
cookie = sharedObject.ge tLocal("date");
if (cookie.data.ex pire == undefined) {
cookie.data.exp ire =
(currentDate.ge tDate()+7)+"/"+currentDate.g etMonth()+"/"+currentDate.g etYear
();
cookie.data.tod ay = today;
} else {
sepToday = cookie.data.tod ay.split("/");
sepExpire = cookie.data.exp ire.split("/");
if (Number(sepToda y[0]) >= Number(sepExpir e[0]) && Number(sepToday[1]) <=
Number(sepExpir e[1])) {
this.stop(); //stay stopped on frame 1
} else {
this.gotoAndPla y(2); //Play movie
}
}
cookie.flush();

How can I test it?
I mean....I tried searching for a file called date.sol here but couldn't
find it.
Is there a way I can sort of reset the system to test the script's
functionality?
And to change the expiration period I understand I need to change the number
here:
currentDate.get Date()+7
Am I correct?

Thanks in advance for your big help :)

Should be new Date() , although your version may work.

Wrong month, see via FAQ. As an apparent Canadian, you should have
noticed that D/M/Y, though moderately logical, is often
indistinguishab le from M/D/Y which your neighbours like.

Gives non-existent date if today is in the last 7 days of the month; I
know no reason to expect that to be acceptable. Can give non-existent
month.

Looks as if it may fail around year-end. See below.

Both new Date and new Date() are valid and mean the same thing.

2 Questions:

1) Is that documented anywhere?
2) How do you pass parameters to new Date() if you don't use the ()?

ECMA 262 v3 section 11.2.
The production is:

<LeftHandSideEx pression> -> <NewExpressio n>
-> new <NewExpressio n>
-> new <MemberExpressi on>
-> new <PrimaryExpress ion>
-> new <Identifier>
-> new Date

The evaluation is according to section 11.2.2. First we evaluate the
identifier "Date", giving an object which has a [[Construct]] method.
Then that method is called providing no arguments.

You can trace <LeftHandSideEx pression> back to something that is a
valid right hand side as well :)

It's documented for JScript on MSDN:
<URL:http://msdn.microsoft. com/library/default.asp?url =/library/en-us/script56/html/js56jsoprnew.as p>

It works like this in JavaScript 1.0 in Nescape 2, so it's a good
bet it has worked in most browsers since then.

How do you pass parameters to "new Date()" when you don't specify any
parameters? :)

Omitting the parentheses means that the constructor is called with
no parameters, just as using parentheses with no arguments inside them.

ECMA 262 (3rd edition) section 11.2, particularly the first algorithm in
section 11.2.2 (production == NewExpression: new NewExpression). Where
if the operand of the new operator is evaluated and the internal
GetValue function applied to the result returns an Object with a
[[Construct]] method (so a function object), its [[Construct]] method is
called with no arguments.

Arguments are only passed to the [[construct]] method in the second
algorithm in section 11.2.2 (production == MemberExpressio n: new
MemberExpressio n Arguments).

However, knowing that I can use the - new - operator without any
parenthesise in javascript if arguments are not needed, doesn't
encourage me to do so.
