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 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 test to see if an Object is an associative array?

There's one bug that I just can't seem to fix. I've marked the problem below in GREEN. It's best if you read COMMENT 1 before COMMENT 2.[code]...
lets say i have an array called numbers with these values: 0,1,2,3,4,5,6,7,8,9,10i want to call a random number of that array, something like this:
Code:
rand = Math.round(Math.random()*(_root.numbers.length-1));
no = numbers[rand];
then when ive got my value (no) i want to delete it from the array... and thats thproblem... i tried to convert the array to a string and then slice it
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.

i have a simple array, for example: ( 50, 20, 60, 30, 10, 8, 15, 25) but need to output it in ascending numerical order ( 8, 10, 15, 20, 25, 30, 50, 60 ). Any one have a handy code snippet to do so?
View 7 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.
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.
I have been working on sorting Arraycollection like ascending , descending the numeric list. Total length of my collection will go up to 100. Now I want to preform sort to nested data like this
Data Structure
Name : String
Categories : Array ["A","x or y or z","C"]
Categories array will have maximum 3 items , out of that three items the second item can have 3 different values either X or Y or Z. My result data looks like here
{"Mike" , ["A","x","C"]}
{"Tim" , ["A","y","C"]}
{"Bob" , ["A","x","C"]}[code]....
anyone please explain how to sort this type of data in a way showing all "x" first , "y" next and "z" at the last and vice a versa.
I'm working with a web service and am returning an array to a field (that I set the data type as an Array). The result thus far is "[object Object]". How can I get the array values back out as a string?
View 0 RepliesIs there anyway where I can pass the Array values (not the array collection values) to the Bar charts or column charts using flex 3.5...
here is the thing i want:::
I have array values like this,,
array1 = [23, 49, 40, 239, 20, 80, 39,49,120, 24, 31,41];
and i want to show these values on the Yaxis and months on Xaxis....
I have two Qns,
1) how can I pass this array to Bar chart or column chart.
2) how do I need to show months on Xaxis. beacuse I'm asking this regarding, I have kept a filters that even if we want to see some months or a particular months or perticalar span of months... there on Xaxis it need to change the months dynamically depending on the filters..... (for ex, on Xaxis the values should be (Jan, Apr, Jun,Oct) if i select the 3 months period filter....)
I have written a logic to collect the values of those particular months into an array, but not understading how to pass this array to Bar chart,, beacuse there I don't know what Xfield and Yfield to be given....
I'm trying to use associative arrays to store my variables but am looking for a solution to change the value of array1[i] to array2[i]. Since it's an associative array, the only way I know how to loop through these kinds of arrays is by the following:
Code:
for(var i in array1) {
trace(array1[i];
}
What I would do when using indexed arrays to change the value of array1[i] to array2[i] would be something like this:
Code:
for(i=0; i<array1.length; i++) {
array1[i] = array2[i];
}
However, I can't see any way you can do this with associative arrays because they do not have a numbered index such that in a loop you could
say array1[i] = array2[i] .
So I'm looking for a way to do this with associative arrays.
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();
[code]....
I seek help in converting the following working code of Associative Arrays into the Indexed Arrays.[code]
View 8 RepliesI have an xml with an xml-schema. The xml-schema defines an abstract complex type with 2 optional attributes that have default values. Then I have several complex types that extend the base one. And finally nodes of the types defined.So I load the xml and when I parse each node, the optional attributes are not present at all.I've tried fooling around with the namespaces, even[code]...
No luck. Something similar was being experienced by this guy on codingforums, but that was like 5 years ago. Same is happening to me with firefox 3.0.11 - the xml is shown without the default attributes.For now I'm setting the default values in code, but isn't there a way to make them available from the xml-schema?[code]...
I have a tree with nodes , and a delete button , first user select the node and click this delete button , I want this node to be removed from the tree , Its not XML , every node in tree is of type Object
{label:'folder',children:[{label:'file1'}]}
I tried delete myTree.selectedItem (but compiler wont let me do it) also tried myTree.selectedItem = null (just unselects the item)and also how can I access reference to parent object of myTree.selectedItem ?
How to make a kind of array that index things based on a object? but not being strict like dictionary.
What I mean:
var a:Object = {a:3};
var b:Object = {a:3};
var dict:Dictionary = new Dictionary();
dict[a] = 'value for a';
// now I want to get the value for the last assignment
var value = dict[b];
// value doesn't exits :s
How to make something like that. To not be to heavy as a lot of data will be flowing there. I have an idea to use the toString() method but I would have to make custom classes.. I would like something fast..
I have a multidimensional array based data and i'm pretty confused in bringing it to simple linear array. I know it requires some for in loop to set property and its value and some nested looping but i lost in the half way.

name = gender;
records:Array

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.

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.

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
