ActionScript 3.0 :: Copy An Object Using As An Associative Array?
Sep 1, 2009I need a simple way to copy an object I use as an associative array. I use Flash, not Flex, so apparently copy() is not an option - or is it?

View 2 RepliesI need to remove the value associated with a property in a Flex 3 associative array; is this possible?
For example, suppose I created this array like so:
var myArray:Object = new Object();
myArray[someXML.@attribute] = "foo";
Later, I need to do something like this:
delete myArray[someXML.@attribute];
However, I get this error message at runtime:
Error #1119: Delete operator is not supported with operand of type XMLList.
How do I perform this operation?
Is there a quicker way besides iterating thru all entries in the associative array Related to - How do I delete a value from an Object-based associative array in Flex 3?
View 2 RepliesIn actionscript 2 I was able to make indexed associative arrays. Ex:
var arr:Object = new Object();
arr[0] = {var1:"one", var2:"two"}
arr[1] = {var1:"a", var2:"b"}
In actionscript 3 I cant seem to do this.I get the error below.TypeError: Error #1009: Cannot access a property or method of a null object reference.
how to copy one xml object values from one xml object to another empty xml object.
I have one xml object from the xml array and need to copy that to another xml object. How can i copy xml from one object to another
if am parsing the XML object with for loop and i get the nodes
var myXML:xml = new xml();

hey, I was wondering if there's any way to push a copy of an object onto an array without having to create a seperate variable for each object.
For example- in c, i'm used to doing something like having a 'temp' object- and then in a loop i would set the value of the objects members and push it on to the array (vector). If i try to do something like that in flash though, it stores a reference to that object in the array, so every time it changes every new element in the array changes to have the latest values of the temp object.
Without using as2.0 classes (i.e. just mx style) is there any way I can get the effect i'm trying to get here- just have one instance of an object that i can redefine in a loop and push a copy of it into the array so that i wouldn't have to declare a separate variable for each one which would defeat the purpose of the array.
In the code below, i create an object and stick it in an array, then I make a duplicate of that array. I loop though the duplicate and change the value of one of the props of the object in the duplicated array. Doing this however unintentionally changes the prop value of an object in the original array. I'm assuming that the objects in the duplicated array are mere references to the objects in the original array. Is this correct? And if so, how do i make unique copies of those objects in the original array, so that changes made to the objects in the new, duplicated array are exclusive to those objects?
I know that i could probably make a new object when duplicating the array, and then recreate each prop, assigning values from the original objects.. but this is a simplified example. The project im working on has many props for each object, so, id rather just make copies if at all possible.
Code:
var testObj:Object = new Object();
testObj.prop1 = "hello";
//
var testArr:Array = new Array();

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 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 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;

myarray['array3'] = 213;
myarray['array1'] = 321;
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

Is it possible to create an associative array w/o using a variable to pass it as parameter to a function?[code]...
View 1 Repliesin 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.
studentNames[name] = studentNames[name] ? studentNames[name] + 1 : 1; // shudder

View 6 RepliesHow do I push an entry into an associative array?
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'});

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?
I need to create a associative array from a text file, but I don't know how I go about doing it.

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
data[0] -> [0] blue, [1] 1984, [2] wednesday
[1] -> [0] green, [1] 1926, [2] friday
and a simple array of keys/properties (header array) like so:
[0] colour, [1] year, [2] weekday
I'd like to insert the keys to make
data[0] -> [colour] blue, [year] 1984, [weekday] wednesday
[1] -> [colour] green, [year] 1926, [weekday] friday
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.
How do you find the length of an Associative Array? The standard "arrayName.length" returns 0.
View 2 RepliesLets show some code:
x = new Array();
x['kamil'] = new Object();
x['kamil'].name = "kamil";
x['madzia'] = new Object();

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.
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?
