Actionscript 3 :: Delete A Value From An Object-based Associative Array In Flex 3?

Jul 20, 2009

I 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?

Flex :: 1020 Undefined Property Right After Associative Array Defined Via Var?

Dec 29, 2009

While developing with Adobe Flex, I'm working on my first application - and use pretty much actionscript.

In my mxml application, I include as3 file via <mx:Script source="as/myas3file.as></mx:Script>.

In myas3file.as, I include (thru include "variables.as";) file variables.as, which contains following code:

var timer:Object = new Object();
timer.t = 60;
or (in other test case)
var timer:Object = {t:60, j:"80"};
timer.t = 80;

Neither case works! Even if I rewrite example code from official documentation, it throws an 1020 error.

ActionScript 3.0 :: Nav - Adding The Thumbnails To The Display Object Via An Array Based On An External XML File

Jan 30, 2009

I'm going to be building a site for a photographer and would like to be able to do something like the thumbnail navigation in this example: [URL] I'm assuming it's adding the thumbnails to the Display Object via an array based on an external XML file, and displaying them once their corresponding full-size images are loaded ... Perhaps it's building the nav simply by looking to see how many photos there are in a folder on the server (i.e. no discreet XML added for each shot). Not sure if this idea is even possible -- would like to hear from any of you if in fact it is.

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?

Actionscript 3 :: Using Associative Array To Count Occurrences?

Dec 1, 2010

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.

studentNames[name] = studentNames[name] ? studentNames[name] + 1 : 1; // shudder

ActionScript 2.0 :: Push An Entry Into An Associative Array?

Jul 12, 2010

How 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'});

[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?

ActionScript 3.0 :: Assign Keys To Associative Array?

Feb 14, 2011

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.
