ActionScript 3.0 :: Associative Array Does Not Allow More Than Two Keys?
Apr 27, 2010
I am writing to ask if there is anyone on the list tried to find out the index of elements of an associative array.
[Code]....
See, these are all part of regions array, which I believe is an associative one by the way I constructed it. I tried to use indexOf to find out the index of the individual elements, but don't seem to have too much luck.
ActionScript Code:
for (var s:String in regions) trace("
" + indexOf(s));
Right now, this does not bring me a thing. Have I done something wrong here?
I have a multidimentional array already made, brought in from a CSV file via csvlib.I also have the headers in an array and I would like a way to assign this array as the keys for the arrays.here's a simplification. have a data array like so
i've read up into associative arrays a bit and am not getting how to do this. (there's 38 properties so remember which is which is going to be quite inconvenient).I sort of thought csvlib would do this automatically but it appears the headers just exist completely independently.
If I have an associative array, say, cars = {make: "Honda", year: "1997", model: "civic"} is there an actionscript function to retrieve just the keys, (namely make, year, and model)? If not, how could it be efficiently done?

I have an array of objects which uses a delimited string as the keys. When examined in the FB4 debugger, the keys look like this:[code]The first two items are numeric (cast to string) but the third item in the multi-part delimited key is naturally a string -- it's like an alphanumeric library shelf reference. As expected, when you click on the [+] icon in the debugger, you can view the object associated with that string key. So far so good.The debugger shows the keys in the (pre-sorted) order in which they were added to the array. However, when iterating the object array so:[code]the keys are returned in some other order --internal hash? My question is, how does the debugger know the order the keys were added in, and can I access that knowledge at runtime when iterating the array? I want to iterate the objects in the order in which they were added. Or do I need to maintain my own index of these keys showing the order they were added to the associative array?
I'm looking for the javascript way to an associative map/array/hash that's using objects as keys. A replacement to what you can do in ActionScript 3 with the flash.utils.Dictionary. I'm sure java and C# have something like it too.It'd work same as a normal generic Object based assoc[key] but instead of string-based properties you use whole objects as keys (it will match not on toString() like Object does but on unique instance). Very handy to decorate objects you don't own (by using the object as keys and your decorations as value).[code]Main point of issue is I need to match on object only (it's being used by some other process you're not to interfere with but we still need association). So no magic .__hash props or toString() overloading (if possible).
In the below code, "sector" is an indexed array.fsector1, fsector2,fsector3 are Associative arrays.The "gotoAndStop" command doesnt work properly.The last trace command, "curTerr" returns the same value as "curSec",leading me to assume i did not define "curTerr" properly.
Actionscript Code: function loadmaptest(){ sector = ["fsector1","fsector2","fsector3"] fsector1 = new Array(); fsector1["terrain"] = "grass"; fsector2 = new Array();
I have an associative array that I want to display using TileList. However, it doesn't understand what is being fed to it. All I got is [object] in the TileList.
[bindable] public var people as array = new array(); private function loadArray():void{
I have been following tutorials but they don't seem to cover exactly what I'm doing.I have an associative array of values called definitionsArray which I use as references to instantiate classes in a run time shared library.I instantiate and push the object into a new array. The problem is when I try to access or do anything basically with that new array.As they are objects they don't seem to like being in a display list for example.
ActionScript Code: var definitionsArray:Array; var bubblesArray:Array;
I have loaded XML into flash and everything is great. I have an Associative Array that makes a dynamic menu and everything is great.
What I would like to do is combine the two and have my loaded XML fill up the Array and the dynamic menu.
Here is the XML portion:
Actionscript Code: //Importsimport flash.net.URLLoader;import flash.net.URLRequest;import flash.events.Event;//Create XMl variablevar teamsXML:XML;//Create URL Loadervar xmlLoader:URLLoader = new URLLoader();//Tell the URLLoader named XMlLoader to listen for the xml //file to finish loading, then run the function
in many programming languages there is this great idiom that lets you use a hash to count occurrences of items. Eg in Perl, suppose you have a list of students and you want to see how many of each name you have (2 Bobs, 1 Jeremy, 22 Aidans etc):
my %uniqueNames; for (@studentNames){ $uniqueNames{$_}++; } # print it out[code]....
So you can do this in ActionScript 3 of course, using the Object.The problem is NaN. If you try to autocreate and autoincrement a key at the same time, you get NaN, and the whole thing breaks down.Sure, you can use a conditional to test whether the key exists, and then autoincrement it, or set it to one if not, but that's ugly.
how to delete an element from an associative array? Splice doesn't work and I tried using the delete action but this doesn't produce the desired result....the element's properties become undefined.
ActionScript Code: var lijst:Object = new Object({fname:'John', lname:'Carpenter'}); lijst.push({mname:'Frank'});
[code]...
This doesn't work. The first name and last name work because they are created when the object was created, but the pushed middle name remains undefined.I understand that associative arrays are in fact objects. I tried turning it into a real array so the Push command would work cause it's part of the Array Class.
ActionScript Code: var lijst:Array = new Array({fname:'John', lname:'Carpenter'}); lijst.push({mname:'Frank'});
[code]....
Though this works, it only works when using a '1'. When in fact I want to keep it inside the '0' entry.So how do I really add an entry into an assciative array? So that in above example instead of each having two elements one is added resulting in three elements per entry?
x = new Array(); x['kamil'] = new Object(); x['kamil'].name = "kamil"; x['madzia'] = new Object();
[Code]....
How to remove any element from that array when instead of indexes we have names; such as kamil or madzia. pop, shift, slice, splice and so on... dont work at all.

I am writing this post because i have not found an answer to this. I wrote a class that will get several function names and then proceed to call them. Thing is, i want this code on a base class, which is on a separate swc.
[Code]...
If i override the createThing function, and add the exact same code, there is no problem. Is there a way around this? I think this is a bug on AS3 not distinguishing its real context, but i am not sure.
