Actionscript 3 :: Determine The Index Of An Element In Array That Has Been Clicked?
Jan 3, 2012
Say, I have an array of movie clips (dummies). Each dummy has an event listener and reacts to clicks. And when a dummy is clicked, I want to know the index of the clicked dummy.
I've only come up with this solution: run through the whole array of dummies and find out which dummy is the target, then exit the 'for' cycle and assign some global variable the value of counter variable, but this way the application I am building will demontsrate poor performance.

I'm trying to create a virtual keyboard.
I have a class VirtualKeyboard which contains an array called keyboard of 26 movieclips, each one representing a letter.
In the main class, I create an object of the class VirtualKeyboard and added an eventlistener on it when a letter is clicked.[code]...
But the index always returns the value 4294967295.
How can I know which letter was clicked, I mean the index in the keyboard array corresponding to that letter?
The same code is working correctly if I put it in the VirtualKeyboard class, but not from the main class.

In the main class, I create an object of the class VirtualKeyboard and added an eventlistener on it when a letter is clicked.
I tried this in the event handler :
var objectClicked:Object = event.currentTarget;
var index:uint = virtualKeyboard.keyboard.indexOf(objectClicked);
But the "index" always returns the value 4294967295
So how can I know which letter was clicked, I mean the index in the keyboard array corresponding to that letter?

I search the stage for the level I created and put the floor pieces into an array. I'm trying to test the properties I created for each piece by tracing to output when the hero sprite is within the floor pieces sides. This works fine when I specify the array index to do this for, but does not work when I try to loop through every element of the array. I see no reason why this code should not work.
package {
import flash.display.*;
import flash.events.*;
import flash.utils.getTimer;
import flash.utils.Timer;
public class MegaManTest extends MovieClip {
private var hero:Object;

In below class I ave declared an array "selectedOptions". In click event Im storing the values in it. But everytime I click on the object the array gets initialized and stores the clicked element rather storing all the elements one by one. Could you tell me the reason?

So, for sending to individual streams we have to reference the connected netStream we want to send to in some way like this:
sendStream.peerStreams[0].send("MyFunction",param1,param2);
and I have to determine which peer I'm sending to by their ID such as "peerID1234"
I know that you can check the peerID of the stream by doing:
sendStream.peerStreams[0]["farID"]
how can I make my send stream function know to use the array index where the peerID is?
so basically it could be like:
sendStream.peerStreams[where peerStreams[]["farID"] == peerID].send("MyFunction",param1,param2);

I have a simple list in Flex that is populated every N seconds by a dataprovider. My goal is to avoid scrolling the list after the dataprovider has been changed.
So, before I populate the list, I save the selectedIndex, and once the dataProvider is filled, I call:
list.selectedIndex = index;
list.scrollToIndex(index);
Trouble is that this moves the selected item of the list to the top. The solution would be to get the index of the first element displayed in the list: but I have no idea on how to get that.

I have an XMLListCollection object that contains items with an ID property. I want to find one particular item by id and then get it's index in the collection. This is done to be able to tell the comboBox (whose dataProvider is the XMLListCollection) the index of the item to display.

I'm writing an app where I want to know which, of an unspecified set of buttons, the user is clicking.The actual location of buttons determined by previous user actions, so I cant use information like mouseX.You can see from the code the way I'm attacking this - trying to access the button based on its position in the display list of a container. Unfortunately this has always led to type coercion errors 0 - AS can't see that e.target is a DisplayObject.se has solved this problem.
ActionScript Code:
import flash.display.DisplayObject;
import flash.display.Graphics;

Now this is all within the forloop function on frame1. what if I want the actions to occur on frame 2 of the main timeline after the coinciding thumb has been clicked. How can I determine which thumb was clicked? I tried using a _global.id = i; but that doesnt store the correct value from the loop.

Here is the problem I have: after I change the index of one movieclip using this code
oldIndex=getChildIndex(DisplayObject(e.target));
setChildIndex(DisplayObject(e.target), numChildren - 1);
when I give the object its old index
setChildIndex(DisplayObject(e.target), oldIndex);
and go to another frame of the movie, this element I have changed the index of stays on top of all elements on the new frame. My question is am I doing something wrong and if not, what can I do so that this element stays only in the frame it is placed.

I am using browseForSave() to give the user a chance to save a file before navigating back to a previous screen. As of now the cancel button on the save dialog just closes the save dialog. I want to see if the cancel button was clicked, and if so continue navigating back to the previous screen without saving. Right now the person has to save the file in order to move back. Below is the code I'm using.

I have several array element each assigned to different symbols on the stage and now I have assigned one function (fcn1) for each element's MOUSE_OVER event as follows:.
for(h = 0; h < fields.length; h++)
{
fields[h].addEventListener(MouseEvent.MOUSE_OVER, fcn1);
[code]....
Now in fcn1, I have to identify which element the mouse was over it. I could not do this because I can't pass any parameter to fcn1 other than e:MouseEvent. And I tried to look the properties and methods of e:MouseEvent that might give any information about the source element (in this case, array elements).So far, only way out of this was I create function for each array element which in turn call fcn1 with appropriate parameter, but it is cluttery.

i have a tree component that dispatches an itemOpen event. When the black triangle next to the yellow folder is clicked, that folder opens to expose its children.
Is there anyway to know the index of the open folder? there is a rowIndex property in the target property of the openItem event that stores the index but it is not accessible.

I'm trying to check if a clicked element is inside of an IVisualElement in Flex 4. So I want something like "if this element is in this element, then execute function". I'm aware of the 'parent' property but this doesn't seem to work when my element is not a direct child of the element but for example 3 levels deep.

I have used a method to shuffle a part of a Array, but i noticed that it does not work very well.When i run this method I sometimes get empty array values.So if you would try the example below and test it out some times you would get a right result but sometimes a wrong result.For example when i run this i get in my trace output:
a,b,c,d,g,,e,f (here after the g it goes wrong)
a,b,c,f,g,d,e (here it goes right)
a,b,c,d,,g,f,e (here it goes wrong)[code]...

Is it possible to, if you have an array of class names like ActionScript Code: var city01names:Array = ["pic_01", "pic_02", "pic_03" ...] make a new array which would read these names, instantiate them, and push them into a new array containing the instances of all these pictures, which I could then use for a slideshow?

I have an array called dropTarg1 which stores dropped-in items.I want to loop through this array and in a textfield, display each array item on a new line of this text fieldI think I need to use something like Array.join("/n") but I can't get it working properly. I hope that the /n would create a new line of the text field called reviewBoxContentText.
for(var i:Number = 0; i<dropTarg.length; i++){
with(reviewBoxContent.reviewBoxContentText){

I have 4 buttons and an empty array. When a button is clicked,I'm adding a element to an array with array.push. However, I want to check the array 1st to see if that element exists. If so, then don't add it. Here's what I have thus far
[Code]...
Now I'm taking it I'd have a conditional statement to see if the element already exists. Unfortunatly I cannot just disable the button. I searched the AS dictionary but oddly enough it doesn't have an easy way to search an array. And IndexOf seems to only work for a string.
