ActionScript 3.0 :: Aggravating Sparse Array For/next Order Vs. Need For .length?
May 21, 2009
it would seem (and I guess I read Senocular's thing on this ages ago, but never really believed it)...
Code:
var a:Array = [];
a[0] = "a";
a[1] = "b";[code].....
But make it sparse and it all goes to hell... i.e. if a[0] isn't defined, cases where you're using it as a piece of useful information, there's no guarantee they'll spit out in the same order.On the other hand, if you make it an object, you can't get its length.Does anyone know an elegant way to poll an Array for the number of occupied addresses, and allow it to for/each or for/as in the right order? In PHP it's as easy as count() and foreach(... as $k=>$v). While the latter doesn't do much good for associative arrays, it always works in order on numerical arrays, whether sparse or not...

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.

Another thing. How can I add a value in the first position of the array pulling keeping all the other values jumping to the next position.

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];

I have an ArrayCollection of Objects. Each Object with three attributes:CustomerID, Income and DateMy goal is to chart this data for each customer (or a couple together) in a Income by Date LineChart display. Selection of customers is done with ArrayCollection filters.Data is fetched from an SQL database, however, each customer has some data points missing.f there was zero income on August 8, 2010 there will be no entry for that.Charting the ArrayCollection as is, is misleading because there is no indication of the missing data points.One way to solve this is to artificially add zero points for the missing dates for each customer. However, this would explode the data set (and impact performance).

this 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'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("");

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.

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

I 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.

How 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;
_global.xmap = 4;
for (y=0; y<_global.ymap; y++) {
for (x=0; x<_global.xmap; x++) {
_global.map[y][x] = 1;
}} trace(_global.map[4][4]);
