how do you pass a variable to a listener function? Im trying to add bmp when the mouse goes over this class but i keep getting the undefined error.
Code:
package FlashPackage{
import flash.display.*;

Let's say I have 10 different buttons, a click on each button will open a different website. Currently, I have 10 different functions for 10 buttons. Is there a way to simplify the code and only have one function for all the buttons and only pass the URL to the onclick function?
button121.addEventListener(MouseEvent.CLICK, clickButton121("http://www.myurl.com"));
function clickButton121(event:MouseEvent, urlString:String):void{
myURL = new URLRequest(urlString);
navigateToURL(myURL);
}
I can say it will be very inefficient if i have 100 buttons and having to write 100 functions.
I am wondering what is the way of passing and argument to a listener.. doing something like this:
Code:
myThing.addEventListener(Event.COMPLETE, doThis(arg));
function doThis(e:Event, arg:int){
...
}
What is the proper way, i this doesnt really brake the code, it doesnt work either...
I'm new to ActionScript and have a fairly basic question. I want an eventlistener to call a function and pass it a parameter that will send the movie to a specific frame. My code generates and invalid parameter type error. It's as follows:
TL_AboutUs_btn.addEventListener(MouseEvent.MOUSE_OVER, DropSubMenu(10)); // calls a function to drop a sub menu
function DropSubMenu(sm:number)
{ gotoAndPlay(sm);}
Error is "1046: Type was not found or was not a compile-time constant: number."
I have one event handler for several object's events. I would like to pass a value through to the function from the event listener:
function chkEmpty(event:Event){
if(event.currentTarget.text==){
thisIsBitIWantToBeAbleChange.text = You haven't entered anything in the box, please try again
hisIsBitIWantToBeAbleChange.setTextFormat(validate_frmt);
}
}
Could I give the event.currentTarget a value that I could test for? So if the value is 1, I effect output1_txt, if 2, output2_txt, etc etc. If so, are there customisable values that I could use that wouldn't do anything to the display object,?
I would like to know if it is possible to pass a clip event on to both the function that has a listener, and to the button that is being pressed. I am finding the listener takes it and thus the button doesn't see it.I found a walk around, however, I'd like to know if it is possible say for one clip event to be seen by both objects?For example, with the mouse over a button the listener function detects the event and carries itself out, however, the button misses the event now.
View 2 RepliesI am trying to essentially pass a string as a function name into an event listener, but I am not sure how to approach this. Is there a way to convert a string into a function?

I'm using the following addlistener to listen for a custom event the event works if i put e.Event in the functions parameter but i don't get the passed variables however if i go into the .as folder where the dispatch originates and put EventType in the parmeters field of the function then i get all the variables.........but if i put EventType instead of e.Event in the first example then I get undefined for EventType.....how do give access to EventType?

I used to actuate the painter function by using a MouseEvent although I'm prefering to do it this way, but I'm having issues with an error "1120: Access of undefined property thisMouse." Error in Bold I've attempted to pass the Mouse Event to the painter function but had no luck. A simple solution (even potentially dangerous and WRONG) would be fine here, as this is part of University Coursework and I haven't been taught Classes etc. Its basically an introduction to scripting but im trying to do things slightly out of my depth
I am familiar with event listeners, of course, but I was wondering if it was possible to pass along a variable with an event. For example:
ActionScript Code:
button.addEventListener(MouseEvent.CLICK, doSomething('yay'));
function doSomething(e:MouseEvent, s:String)[code]....
if someone clicks on the mc named 'button' I would like this to trace the text 'yay'.
Is there a way to add an event listener to a variable?
View 4 RepliesI was wondering if there was a way of tracking a variable change? Perhaps using some sort of event listener for it?
View 2 RepliesI headed some problem which can't solve. It's simple. I'm making slideshow, and wanna pictures to be dynamically loaded. List of images is stored in list.xml - a valid xml file. Now, here is piece of the code:
var imgno :Number ; //the var which tells the number of images listed in list.xml
var myXML:XML;
var myLoader:URLLoader = new URLLoader();
[Code]....
So, the triggered function processXML cannot change value of any variable which stands out of her. Is there a way to export (in this case) information about amount of images listed in list.xml to some of the variables that I can use later (for example imgno).
How do i pass a variable to a function from an event listener which is inside a function Below is a function that is called when after loading some variables
function dataOK(mydataevent:Event):void{
var j:int = 0;
do {
trace(j);
[Code]....
This is a simplified version of the original code. The above function generates an error because j is undefined in the function. I am wanting to get the variable j when the button is pressed.
How do I pass the variable j to the Button_Click function?

I have 3-4 swf those i want to load one after another like a slideshow.What i want to do is get the total frames of loaded swf and want to pass that value to Timer object's delay parameter. i have converted total frames to milliseconds so i can use it in timer constructor. But i am not getting the value of that variable outside of my Event.COMPLETE listener method. Here is my code what i have done

Is this a valid way to completely clean up a variable/object event listener (code abbreviated for sake of example):

This has been driving me nuts. The short of it is that I have a main movie that loads smaller swfs. In the main movie, there is a textbox that holds descriptions of the smaller clips.What I am trying to do is this: When the user clicks a button in the loaded swf, a string variable "feedback" replaces the text in the description text in the parent clip.Here is the code I have. I have been searching this for a while now and have tried various things, so this may be way off base. The clips load fine and everything, I just can't figure this one piece out.I am only showing the relevant code because there is a LOT of other working code. If anyone needs more info, let me know.Main Clip
Code:
clipLoader.contentLoaderInfo.addEventListener( Event.INIT, onLoaderInit );
function onLoaderInit( e:Event ):void {

I have 2 functions. Each one is being called by a different event listener. Both event listeners work because I am able to trace strings in both of them.. my problem is that i am trying to create a variable that is local to both functions. The first function "working" adds a number to the variable and when the second event listener triggers function "notworking" which retrieves this same variable called "counting" both functions are called automatically by event listeners.. how do I do this? i am stomped!

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.
View 3 Repliesif 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.
View 3 RepliesI'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.
View 1 RepliesThis 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:

how can i access event.target outside event listener method.say for example
my_mc.addEventListener(MouseEvent.CLICK, onC);
function onC(e:MouseEvent):void
{
var m:MovieClip = e.target as MovieClip;
}
trace(m.totalframes);/// not working
now what if i want to get totalframe property of m instance, in short for every movieClip clicked.
I am doing this inside a module containing viewstacks and their childs.Calling onInit() on creationComplete of module.When I am inside one of the childs of a viewstack of this module and press Enter, it doesnt not invoke the listener function at all (bp inside this does not get hit).
private function onInit():void{
this.addEventListener(KeyboardEvent.KEY_DOWN, keyPressed);
}[code]..........
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 these buttons in a movie clip and I would like to have only one event listener for the parent, using event.target to point to the children. I have also tried event.currentTarget, and it didn't work.here is the code that works:
test01.abtn.addEventListener(MouseEvent.ROLL_OVER, mouseHandler);
test01.bbtn.addEventListener(MouseEvent.ROLL_OVER, mouseHandler);
test01.cbtn.addEventListener(MouseEvent.ROLL_OVER, mouseHandler);[code]....
It is only targeting the movie clip, not the buttons inside the movie clip.
