ActionScript 3.0 :: Using A For Loop To Add Event Listener To Multiple Buttons In One Go?
Sep 8, 2009
Basically i am loading a series of URLs in from an XML file and i want to assign them to each button on stage (the number of buttons on stage and the number of URLs in the XML doc will match). They will correspond, so myButton1 will go to the first URL in the XML file and so on. I also want to declare button mode true on all the buttons on stage (they are actually movie clips) but i just don't know the syntax of how to do it in a for loop without writing the whole thing out in a really long winded way.Here is my code:
Code:
var myXML:XML;
var buttonURL1:String;

I'm trying to figure out if it's possible to run multiple buttons using a single addEventListener so that I don't have to create extra code. For example, in the code below I have my instance name "btnCA" which is on my movie clip. It works great and there are no issues with this code, but I need to add more buttons. Does that mean I have to copy and paste this code for each button or is there a way to add multiple instances to an event listener?
Sample code:
buttonMode = true;useHandCursor = true;
var rewind:Boolean =

This might be more of a subjective question, but is it generally best practice to have one dedicated method per event-types that you add an event-listener?
Such as:
myButton.addEventListener(MouseEvent.MOUSE_OVER, onMouseOver);
myButton.addEventListener(MouseEvent.MOUSE_OUT, onMouseOut);
//Somewhere else in the code...
[Code].....
And if you had a MouseEvent.MOUSE_UP, MouseEvent.MOUSE_DOWN and other relevant MouseEvents event-listeners to watch for, you could even set a switch statement to handle all the various MouseEvent types.

I have this list of event listeners I would like to add but no matter how I try to loop it I can't seem to do it Do I need to create a nested loop to specify the function names or would it be possible using just one loop ? :-
gamePage.infoBox.l1i1.addEventListener(MouseEvent.MOUSE_OVER,l1i1Mouse Over);gamePage.infoBox.l1i2.addEventListener(MouseEvent.MOUSE_OVER,l1i2Mouse Over);gamePage.infoBox.l11i1.addEventListener(MouseEvent.MOUSE_OVER,l11i1Mou seOver);gamePage.infoBox.l11i2.addEventListener(MouseEvent.MOUSE_OVER,l11i2Mou

My problem is that mc always referrs to the last mc created in the for loop so the first mc created causes the last one to move on mouseover. Maybe I could use something like "this" or "self"

I am loading several images using a loop. My question is, would it be better to put the "contentLoaderInfo.addEventListener(Event.COMPLETE..." in the loop so it loads the complete handler each time it goes through the loop, or is it fine to put it outside of the loop at the end?

Here is my full code
import fl.controls.*;
var test:MovieClip = new MovieClip();
var btn:Button;
[code]....
Result:
You clicked 8
You clicked 8
You clicked 8...
Is there anyway, such that, I can use for loop to create different name button, and add it to an event listener?

How can i add an event listener to multiple movieclips using a for loop in AS3 so that when i click on a movieclip, flash traces the name of the clip i clicked. This would be it's equivalent in AS2:

Suppose I have a Movieclip and in that Movieclip I have several MovieClips I'm using as buttons.I want all the buttons to do the same thing when I MouseOver. Is there a way I can reference all children of a display container so that I can have a statement like MouseChildren.addEventListener(MouseEvent.RollOver, rollOverHandler) ?

I have been focusing on PHP a lot lately and just had a client that requires an MP3 player playing multiple songs so I had to whip out my rusty actionscript skills. I have the player completed and it is working as desired. The down side is it has multiple songs. I am using separate functions for each song and separate event listeners. My main question is there a way to combine these funtions into one and just use the event listener to pass another variable to the functions? Below is a sample of one of the code for Song1. I would like to make it so anywhere there is Song1 in the code, I can make it a variable so I can put in for example (Song2, Song3, Song4, etc.) This way, I can have one or two functions handle all the songs instead of having to copy, paste and then find and replace.
// Song 1
var Song1:Sound = new Sound();
pbSong1.source = Song1;
//pbSong1.visible = false;
var Song1Loaded:Boolean = false;

I want to setup an event listener on buttons that are on two different frames of "TabContent" (tabs) on my page. I can set up the event listener on the first tab without any issues, but how can I locate the second frame to add an event listener there at the same time?

I“d like to know if it“s necessary to remove event listeners from buttons. I know it's good practice to remove event listeners when its use is over. But it“s necessary to remove event listeners for buttons as well?

I have an interesting problem that I'm attempting to solve and I could use some pointers.Here's a basic run down of the AS3 script:[code]The problem is that the event listener always pulls the url from the last object in the array when you click any sprite (as would be expected).What is the best way to have the event listener only deal with the specific url of the specific iteration that creates it?

So I have an object, generated on each click of the mouse. It's set up as a series of points with properties, with values for position randomly calculated, and set around where the user clicks the mouse. Lines are drawn from where the mouse is clicked out to each of these points, so it kind of looks like a star, but only lines, rather than a solid shape (like those old 50's atom clocks?). So once clicked there's an enter frame event listener on the object so that each of the points 'wobble' (using a randomly generated number) up and down around the original point.
For some reason, I can either set it so that on each new click of the mouse and newly generated object, the last one stops "wobbling" and only the new one does, or each new object moves to where the new object is, and maybe is still wobbling(?), but is underneath the new object. This way has the event.target as a new object in the wobble function, so I think it may be just a case of where the centre point is - i.e. saving the mouse x and y for each object individually, or perhaps I have too much of the setup function code repeated in my "wobble"function?

I was wondering if I had say 10 buttons and I wanted to add them to one event listener, is there a way to set up an array and attach them all to one event listener to cut down on code?

I've been lookign around for this but cant seem to find how to do it. How do you make a array of buttons then call it in a event listener? The idea is that I don't have to creat code for each button. it can just run it over for each button.

The fastforward and rewind buttons on the FLV Playback components don't work like normal ones. If you've tried to use them you'll notice that they respond to a click event rather than a mouse_down event.
By taking apart one of the skins I've found that the fast forward movie clip is forward_mc.
How do I create an event listener for the buttons inside the FLV Playback Component?
If the instance of my FLV Playback component is called "movie," how do I access it? I've tried this, but it doesn't work:

I have multiple items in my app that I would like the user to click on.Some items are completely different classes.The classes dispatch events and then when the events are captured, some modifications are done to the transform properties of a loosely coupled display object.I want two separate classes to dispatch the same type of event, since I already have an image class that draws images based on a given url... I want the classes to dispatch the events, but then I think I want the difference to be detected when the event comes along... i.e., I would like to recognize the 'origin' or 'sub-type' of the event. Some sort of if/then logic would suffice.

I have this for loop that is basically pulling some info from an xml file and putting it in a list box. And for each item in the xml, it also adds 2 radio buttons.Everything is working properly except all the radio buttons have the same y location, and i want them to be spaced apart, not on top of each other.I have tried messing around with the y location (rb1.y+105, etc) but I'm not having any luck.
for (var i:uint=0; i<il.length(); i++) {
lb.addItem({data:il.description.text()[i],
label:il.title.text()[i]});

I have 29 buttons, named img1, img2 ....till img29...I need to access them all in a loop. I had asked this question earlier, but at that time the buttons had to be accessed via their holding movieclip, but this time the code is within the clip, so I need to directly access the button.
So originally the code I was using to access them was
_root.folioholdermc["img"+i]._alpha //thanks to Ned Murphy
now I need to access them as
this.img2._alpha //due to a path change
I tried using
this.img[i]._alpha but this is not working.
I want to put this in a loop where I moves from 1 to 29.

I am using the following AC3 to call a new frame when a button is down. All my instances are named as listed and I double checked that. All the buttons are on different frames. When I just use one it will work, but when I add the others I get the Output Error: TypeError: Error #1009: Cannot access a property or method of a null object reference.at final_project_fla::MainTimeline/frame1() It will allow me to move to frame 5 and 6, but not 7 & 8.[code]

I am trying to learn JavaScript and I am wondering whether JavaScript has a event listener just like ActionScript's ENTER_FRAME. Basically, I want this event listener to listen "all the time" not just wait for any particular instance (mouse click, keyboard event) of event.

if I have an event listerner (mouse, keyboard, enterframe,....event) that is being triggered, and when it finishes its event, something that is able to detect the finished event listener and fire out another sets of event.
It works more like MOTION_FINISH in TweenEvent, but it is only available for TweenEvent only, what if I want to detect a mousclick, keyboard, enterframe or even touch event?

My stage has about 25 buttons on it. Each button when pressed to tweens the background to some random x/y coordinates and then loads an external swf file.This is all working, but the timing is off. How can I wait for the initial background tween to end before I make the loader call to the .swf file.Currently each button's behavior is called on the MouseEvent.CLICK event which calls a function that knows its unique filename.swf. I know you can add the MOTION_FINISH even to the tween event but then I would have to call a new function and lose track of the button that initially called it.

I'm moving on to my next massive programming project and I'm trying to decide whether I should code it in as 2.0 or 3.0. I came across the new click event model in 3.0. Right now it's looking like a pain in the butt to me. So now I have to make a function and add it as an event listener? what the hell? What's the benefit? I understand stuff like this makes AS a more complete language but it's kinda annoying.

This is a very basic question but I can't seem to find an answer. I have a mouse over event and have created the buttons with the mouse overs which is working great. I created the actionscript to go to a specific web page when a user clicks the button. Now, I need to add a label to the mouse over so when someone mouse's over any area of the button, it will show them a particular name for the button.
I am sure that this can be done using actionscript in a mouse event roll over command but I can't figure out what I need to show the text. Here is where I am:
