Re: Re: [Flashcoders] LoadVars array.length problem
Hello :)
for me your method is not good :)
Use JSON or Eden format in your external text file.
Example JSON = Javascript Object Notation ( http://json.org/ )
JSON is better to parse Array, Object, String, Boolean, Number ...
You can use JSON with my openSource framework :
http://code.google.com/p/vegas/
Serialize (ActionScript to String ) :
import vegas.string.JSON ;
var a:Array = [2, true, coucou] ;
var o:Object = { prop1 : 1 , prop2 : 2 } ;
var s:String = hello world ;
var n:Number = 4 ;
var b:Boolean = true ;
trace(* a : + JSON.serialize( a ) ) ;
trace(* o : + JSON.serialize( o ) ) ;
trace(* s : + JSON.serialize( s ) ) ;
trace(* n : + JSON.serialize( n ) ) ;
trace(* b : + JSON.serialize( b ) ) ;
Deserialize (String to ActionScript )
import vegas.string.JSON ;
var source:String = '[ { prop1 : 0xFF , prop2:2,
prop3:hello, prop4:true} , 2, true, 3, [3, 2] ]' ;
var o = JSON.deserialize(source) ;
var l:Number = o.length ;
for (var i:Number = 0 ; il ; i++)
{
trace( + i + : + o[i] + - typeof :: + typeof(o[i])) ;
if (typeof(o[i]) == object)
{
for (var each:String in o[i])
{
trace( + each + : + o[i][each] + :: +
typeof(o[i][each]) ) ;
}
}
}
If your string representation contains an error :
import vegas.string.JSON ;
import vegas.string.errors.JSONError ;
var source:String = [3, 2, ;
try
{
var o = JSON.deserialize(source) ;
}
catch(e:JSONError)
{
trace( e.toString()) ; // output: [JSONError] Bad Array, at:6 in [3, 2,
}
Now.. with a LoadVars :
import vegas.string.JSON ;
var result ;
var loader = new LoadVars() ;
loader.onData = function ( source:String )
{
result = JSON.deserialize(source) ;
trace(result) ;
}
loader.load(data.txt) ;
In your external data.txt you can write an array with the Javascript
notation :
[ 1 , 2 , true, hello world , { prop1 : value1, prop2 : value2 } ,
0xFF ]
To install my framework you can read this page :
http://code.google.com/p/vegas/wiki/InstallVEGASwithSVN
More easy... more speed :)
EKA+ :)

Thanks sebastian,
I had tried something like:
menuLoadVars.onLoad = function(){
var my = menuLoadVars.split(\r);
for (var i = 0; imy.length; i++) {
trace(my[i])
}
}
No joy, perhaps I am using the wrong syntax?

Re: [Flashcoders] LoadVars array.length problem
Dump the textfile idea and use XML instead, which is far better suited for
stuff like menu's.
?xml version=1.0 encoding=UTF-8 ?
menu
item label=about us /
item label=news /
item label=portfolio
sub label=branding /
sub label=interactives /
sub label=marks /
/item
/menu

Subject: [Flashcoders] LoadVars array.length problem
Hello,
I am trying to generate two separate menus dynamically and populated by the
content of tow text files.
The text files have the following info.
menuItems.txt contains:
var1=about us
var2=news
var3=portfolio etc.
submenuItems.txt contains:
var1=branding
var2=interactives
var3=marks etc.
these will be updateable files with any numbers of elements added to or
removed from.
I have this code at the root level:
menuLoadVars = new LoadVars();
menuLoadVars.load(menuItems.txt);
subMenuLoadVars = new LoadVars();
subMenuLoadVars.load(submenuItems.txt);
How can I generate an array that only contains the values of each item if I
don't know the length of the text file?
I have tried:
menuItems.onLoad = function(){
for(i=0; imenuItems.length; i++){
trace(menuItemds[i]);
}
}
but the menuItems.length is undefined and does not return a value.
What can I do instead?
Any tip would be a big help.
Thanks

Re: [Flashcoders] LoadVars array.length problem
That sounds right, even to me, eheheh! I was trying to test my skills with AS. I eventually need to get the data, via PHP, from a database. I suppose I will need to format my php response to produce an xml file but I am quuite new to this and am tentative..

Re: [Flashcoders] LoadVars array.length problem
Hello :)
It's more easy to use JSON ? Xml is more difficult in AS2 ?

Re: [Flashcoders] LoadVars array.length problem
If you're loading data from a file I wouldn't recommend JSON. It's not really readable. JSON is nice for serializing/deserializing data coming from a database or for communicating with for instance Javascript. Not at all for storing data in a text file. Right tool for the job and all that.. regards, Muzak - Original Message - From: eka [EMAIL PROTECTED] To: flashcoders@chattyfig.figleaf.com Sent: Saturday, May 05, 2007 10:07 AM Subject: Re: [Flashcoders] LoadVars array.length problem Hello :) It's more easy to use JSON ?

Re: [Flashcoders] LoadVars array.length problem
Heya John, If the data will eventually be coming from a database, don't use XML. See my previous reply on why not to use JSON with a text file ;-) When communicating with a database I'd avoid using XML (and even JSON for that matter). Have a look at Flash Remoting instead which allows you to receive data in a format that Flash understands. For PHP, there's AMFPHP: http://www.amfphp.org Now with all that said, I'm wondering why you'd want to store menu information in a database at all. Storing this in a database doesn't really make sense to me: about us news portfolio regards, Muzak - Original Message - From: John Trentini [EMAIL PROTECTED] To: flashcoders@chattyfig.figleaf.com Sent: Saturday, May 05, 2007 10:04 AM Subject: Re: [Flashcoders] LoadVars array.length problem That sounds right, even to me, eheheh!

Re: [Flashcoders] LoadVars array.length problem
My apologies Muzak, I think I sent my previous answer to your private email; If i forget to change the address, when i click 'replay' to an email, for some strange reasons, this lists uses the originator's address and not the lists', sheesh! any how Thank you for the info. i have tried to access the page but the server must be down at the moment, i will follow up later. In any case, t he reason I want all the info in a database is so that the client can manage/amend/update the content via a dedicated CMS and be totally independent of the developers (me). Meis a ctually a team of three doing a group project (uni project) for a real client who needs total independence at the end. The client and his staff are not programmers at all so I thought, if I use the databse approach I can use the table names to populate my menues and the content of the tables to drive the content of the site as required. Am I on the wrong track completely? As you can see I am not at a level that will afford me any ease during production so any tips are much appreciated.
