I am trying to get the length of arrays within an array, here is my example (MX 2004):
this.menu.o= ["option1","","container"],["option2","","container"];
context="o";
trace(this.menu[context].length);
I get an output of of 3. the number of variables within the first array, this is not what I had expected.

I get an output of of 3. the number of variables within the first array, this is not what I had expedted.
I am trying to assign a number to a variable that is dynically generated from a binded array...when i try and assign it and trace it out nothing happens, which means I am obviously doing something wrong but I am not sure? just for fun i decided to bind the data to a label like so...

Let's say I have array foo and a positive integer y, where foo.length > y.I want to remove elements from foo so that foo.length becomes y (or very close to it).Also, I need to preserve the first and last element of foo. The indices of the removed elements must be spaced apart as equally as possible. Foo can be sliced, or it can be used to create a new array.
Example: if foo = [a,b,c,d,e,f,g,1,2,3,4,5] and y = 6, then trimmedfoo could be [a,c,e,g,2,4,5] or maybe [a,c,e,2,4,5], but not [a,c,e,g,2,4] because the last element of foo is missing.
I'm just learning so I'm sure I'm making many stupid errors. How do you hitTest 2 separate arrays of different lengths, all entries against one another . Code below for guidance.

I want to compare one value against all values in the other array and extact a match. These are different in length.
Imagine one column of unsorted ID's and one column of ID's and names. I came up with this, but it doesn't work.
private function mergeCollections():void
{
for (var k:int = 0;k <= idArray.length;k++)
{
[Code].....
my arraycollections arrive from database.
The real thing I'm doing here is recieve values from a table full of ids and a table full of those ides, plus the name (they are separate because, normalization dude!) And I want to put them inside a datagrid that will only display the name.
I say possibly unsorted because the second column might reach a point of several deletes and inserts and might end up unsorted. But for this case I have one unsorted column against one sorted column.
My current output is just one name printed, and the rest dismissed completely.
NOTE: Also take in account that the nameArray has always MORE or EQUAL values to the ID table. and the Id table will always have values that match the names table.
I am running into some trouble adding an array into another array to create a multi-dimensional array.The code appears as below:
var slideDataArray:Array = new Array();
var slideShowDataArray:Array = new Array();
slideDataArray[0] = xmlData.SlideShowParameters.SlideShowImagesDirectory;[code]........
I am looking for a means of placing the slideDataArray into a 'slot' or value of slideShowDataArray so that I can in the end pass the slideShowDataArray as a parameter to another function.As of now, the last slideDataArray appears 11 times (the loop runs 11 times) in slideShowDataArray and the way the code is written the slideDataArray is unique every iteration of the loop.
I'm using the .unshift method therefore the newest values go into [0] and the rest are pushed down.
What is a good method to remove a value from an array once it has passed a certain length? For example i only want my array to hold 5 values.
Also, is there a method for clearing the entire array, ie removing all values? Or will i have to manually change all the values with a loop?
im trying to use array.length to get the total indexs of the array, before running a loop on all of thoes indexs when i attempt to do this(i added a few extra things for the sake of debugging and understanding)
ActionScript Code:
var selectcharacternames:URLVariables = new URLVariables(evt.target.data);
trace(selectcharacternames)[code]....
does array.length not work with url variables is it possible to turn url variables into a array(im assuming it is not a array as a reason why this doesnt work)
I have 2 arrays:
Array 1 = [1,3,5,7,9,10];
Array 2 = [5,7,10];
Now, I wanted to create a new Array the is the same as the length of Array 1. The output should look like this:
New Array = [0,0,5,7,0,10];

what's a simple way to combine arrays with as3? by combine, i mean that contents of one array are pushed into another array.I already tried a for loop and push.
View 6 Repliesthis problem is blowing my mind i have a for loop that i want to go through my entire array but it seems to not be counting the last element in the arraay!
Code:
for(var i:int=0; i<gridControl.game.blockG.length; i++){
trace(i +" "+gridControl.game.blockG.length);
}
and the last line of code it spits out is "83 84" meaning that there are 84 items in the array but it only ran through to 83...i dont understand why its doing this.
i have two arrays of DesplayObjects and i want to add all the objects in the second array to the end of the first array, i knew that i just can just do a loop and puch em into the array, but i wondered if there was a simple function for doing this?

I need a way to read the length of my array, automatically create that many frames in the main.fla and read each screen from my array and display it accordingly on each frame. How to do this?
E.g.. In A.xml, I calculated 10 screens, so Ii need to create 10 frames for A.xml....and in my B.xml, I have 25 screens, there Iit should create 25 frames.
I've got some coding to create buttons into an array, and on press of these buttons the function should remove something from another array and remove the last one of the line, so far the coding is working for the first removal, however thereafter the other buttons stay there I think it's to do with the line in bold but I cant put my finger on what's wrong with it! The trace's I've set look plausible...
function removeList (event:MouseEvent):void{
myArray.splice(0,1);
list_text.text=myArray.join("");

I like to use array.length in my for loop to keep my code cleaner to read. Is there any huge downside to this? For example will it speed up things greatly if i store the length in a var one time?

How can I find out the length of the second dimension in a multidimensional array?
this is not working:
Code:
trace(my_array[i].length);
(i being a number incremented by a for-loop (starting at 0 of course))
How would I go about checking the length of a sub array? If I have a code like this:
ActionScript Code:
a = [["a0","a1", "a2", "a3","a4","a5"],
["a0","a1"]];
and I wanted to check the length of the second subarray (the answer would be 2) what would the syntax be?
Edit: the title should obviously be Multidimentional.
As we have in other languages like C, Java that once we define the length of an array we cannot assign any value to the array beyond it's length.[code]This kind of stuff is not possible in C and Java.However AS2.0 calmly accepts the value and increments the length of ii (array) from 3 to 5.Is there any means to restrict the array to accept only particular number of data.
View 10 RepliesI want to know the length of a xml. From a xml file I can make it work. In this case it's a database that generates the xml. So it is a URL, not a Xml. How can I make this work?

url_xml.onLoad = function() {
// this is the array I need from the URL //
var array1:Array = url_xml;

View 2 RepliesI have an array which contains strings. I need to sort the array by the length of the string - longest string first.
e.g. if
myArray[0] = "xxx";
myArray[1] = "x";
myArray[2] = "xxxxxxx";
[Code].....
but it didn't work. I guess length is not a property of each array element.
By the way, the array is already large (270,000 elements) - so I need the sort to work very fast, and I don't want to be adding anything else into the array.
I have a question i need to get the length of an array but outside the onLoad()
here is my code:
var O:XML = new XML();O.ignoreWhite = true;O.onLoad = function(success) {

How do you find the length of an Associative Array? The standard "arrayName.length" returns 0.
View 2 RepliesHow do I set the width of the array and length and set each of the values in it to the same number. This is for a game I am working on. I know you use for loops to find the x and y of the values... This doesn't work, but think its how it suppose to work.
Code:
_global.ymap = 4;
