I have an array that when traced, lets say looks like
Code:
Carrot,Apple,Strawberry,,,Cantaloupe
I'm just wondering, what's the best way to tell if an element in an array is empty?
I'm working with SWFAddress and I have a split function but its also adding empty elements to my array which I want to remove or stop been entered in the array.
Code:
var str : String = '/home/'
var split = str.split("/");
trace("split = "+split.length);
tracer.text = split;
output : ,home,
As you can see the split is coming back with 2 empty elements in the array.The string value could change depending on what the user enters into the url for deeplinking. It could be var str : String = 'home' and this returns the correct value but if the add a slash I need to make sure that is not registered in my array as an empty value. how I could stop these empty elements from showing in the array?
I have a list of 99 item (something like a phone book) and I will like to sort them in different method. Part of the 99 item might be empty, so the requirement is to move the empty field behind the sorted data in every sorting behavior, here the code we have so far:

I've got a fairly simple flash app that searches an xml file and returns text listings of the content of the childnodes back to a dynamic text box for display. The xml file will be edited and managed by an outside user. It works great but if there's an empty childnode (element) it comes back in the list as undefined. I'd like to be able to leave the xml element format the same for the user whether it has text inside the element or not. If it's left empty though, I don't want it to show up. I've seen several ideas on how to handle this but was wondering what the best and most simple solution is.
View 1 Repliesdoes anyone know how to shift all the array elements by one or more without deleting the array itself?
Something like rotating the array:
1,2,3,4,5,6,7,8,9,10
10,1,2,3,4,5,6,7,8,9
9,10,1,2,3,4,5,6,7,8
8,9,10,1,2,3,4,5,6,7
7,8,9,10,1,2,3,4,5,6
I've been trying to move array elements from one array to another using the push method. The problem is that the element pushed should any longer be on the first array where it was taken from. That's where i'm stuck..

View 15 RepliesIf I am a subclass of an Array, how do I access an element?
class ArrayOfFoo extends Array
{
public function getFooAt(anIndex : int) : Foo
{
return this[anIndex] as Foo; // <---- looks for an object attribute (named "0", for example)
}
}
I could wrap an array instead of subclassing it, however lacking a universal IArray interface, that is less than useful for standard and custom functions expecting an Array.
I have a multiple choice quiz designed for a client. I have an array that works thruout the questions, that if the user answers incorrectly, it stores the question number in the array. When the user reaches the end of the quiz, I dont want this array to always display at the end, since the user could have all the asnwers correct (which means the array should be empty). I am trying to make an if else statement that will display a different message if the array is empty.[code]...
View 3 RepliesI have tried several different ways, but it seems that it never sends the empty array value to the server
_vars["myObject[array_list][]"] = null;
_vars["myObject[array_list][]"] = [];
It only seems to work if I provide a value (which I am trying to avoid). What I would like for it to do is send the url param: myObject[array_list][]=& (i.e. an empty value)
I'm trying to make a question game with 30 question divided into 3 dificulties, so i'm using arrays to have my questions randomized but not repetitive.
I made the code use the first parameter of the array (array[0]) then remove it from the array.
So, my array will have no more elements after a time. But, when my array have only 1 element, i cant play this element, and i need to use the representation of the empty array to get it to play.
I'm new on AS3, so this may seem very confusing. Here is the code I used.[code]...
What is the most efficient way to empty an Array or Vector in ActionScript 3?I've always just re-initialized them:
vector = new Vector.<T>();
array = [];
It doesn't look like there's an empty() function or anything similar.
I've been programming a simple shopping cart. The system has several product categories, and in each one, appears a list of products. Each product listing has a numeric stepper, for the client to put desired product quantity.
Now I have two Arrays (lets call them "arrayCat6" and the other "arrayEncomenda6"). arrayCat6 tells me the quantities for each product, even if the quantity is zero. The other is supposed to put only those whose quantity is different from zero.
The question I have is that, if in the products you choose two products, that have another one with zero quantity between them, the arrayEncomenda6 will have and empty entry, between the two products, and I don't understand why. Both Arrays are refreshed each time the numericstepper (of any product) is pressed.
Please does anyone know if this is a bug, or am I forgeting something. The code follows:
function actualiza6(event:Event):void{
var parcial:Number=0;
var aux_preco:String;

How do you empty an array. I want the array complete empty, so the array length =0. I have tried this code, but that doesn�t take away all elements in an array, just a few.
for (i=0; i<myArray.length; i++) {
myArray.pop();
}
What is the easiest way to let a variable refer to all the elements in an array?

View 5 RepliesBasically, there are 24 movieclips with 2 states, empty and full. Their instance names are from space0 to space23. When each movieclip are in the first state, empty what I am "planning" on doing is setting a specific variable for that movieclip called var space0empty:Boolean = true; and when it is in the second state make it false. I would have to make 24 variable for each movieclip. Is there a simpler way to do this with Arrays, also, could you please explain any code given on arrays or at least tell me how to use arrays as the equilivant for what I said with variables.

View 2 RepliesI´m trying to order elements of an array. When the dates come from dynamics text it´s no problem, bad when come from input text the dates are treated like strings and it´s impossible to order correctly, because 15 is considered less than 3.

I'm writing an application in Flex / ActionScript and have a number of class member variables of type Array storing data. My question is: what's the "best" way to clear out an Array object? I noticed the ArrayCollection class has a function removeAll() which does this, but the basic Array class does not. Some possibilities I've considered are:
Iterating through the array, calling pop or shift on each element
Setting the array length to 0
Setting the member variable to a "new Array()" or "[]"
var count:uint = 0;
var textInputs:Array /* of TextInputs */ = [];
for(var i:String in columnsData){
[Code]....
here how can i access the first, second of Array of textinputs in the form of string or any thing to further proceed

I have one array with many elements inside.
ActionScript Code:
var all_id:Array = new Array ["56","42","35","64"];
I also have one cd id, which is dynamically created.Im trying to create a function, which checks if the cd id matches any of the IDs of the array.
ActionScript Code:
for(i=0; i<all_id.length;i++){
if(all_id[i] == id){
trace("ID MATCH");
[code]....
My problem is that - because I'm looping through the elements, I get several traces.Is there a way to get a result if any element matches?
