Define An ActionScript Event Handler Function Inline In AddEvent Listener?
Jun 23, 2010
I have an action listener :myText.addEventListener(TextEvent.LINK,linkClickHandler); As according to this, i need to write an event handler function seperate to handle the text link event.Now my requirement is i need to write that function in the same line isntead of giving its name.ie, something like mytext.addEventListenet(TextEvent.LINK, function(event: TextEvent) {....code comes here....});
can i do like this in AS3.What will the syntax for this if possible.Also i want to know, wether i can pass one more extra param to the event handler other than event which is the default parameter.

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:
PHP Code:
function chkEmpty(event:Event){
if(event.currentTarget.text==""){
thisIsBitIWantToBeAbleChange.text = "You haven't entered anything in the box, please try again"
[Code].....
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 need to return to my original function after capturing an event (downloading something) with another function. The original function needs to return a value, which depends on the downloaded data. So, I'd like to pause original function for the time needed for the download and the eventhandler function to complete it's work, and resume it afterwards.
The obvious way is to set a flag value (both the original function and the eventhandler are within the same class) and make the original function check it until the eventhandler function changes the flag. But that would be wasteful, and my AS is slow enough already:) [other parts of the application utilise some heavy graphics]. Is there another way? Like an event that gets captured "in the middle" of the function? Or some other form of flow control?

Is there a way to get the handler(s) function(s) of an event listener?
I'm trying to find a way to remove them without knowing what they are.
For example:
ActionScript Code:
if (mc.hasEventListener(MouseEvent.CLICK)){
// this object has a MouseEvent.CLICK listener
mc.removeEventListener(MouseEvent.CLICK, null );
}
Instead of null, I was hoping to find some function that retrieves the handler function.

Does anyone know if there is a way to get the name of the function that my code is running inside?
Code:
_btn.onPress = function () {
trace(something);
}
this would then output "onPress" or something like 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.

Ok, I have 2 buttons on the stage. Each button does almost the same thing, so I want to create a single function, and each button calls that same function (we'll name that function "Navigate")... however, the function will need to end up doing something different dependant on which button was clicked.So, previously, in AS2, I would've added some code onto the buttons themselves with on(release) methods, like so:
Code:
// Define the Navigate function
function Navigate(myLabel){

Trying to migrate my way of thinking from AS2 to CS4/AS3. Ok, I have 2 buttons on the stage. Each button does almost the same thing, so I want to create a single function, and each button calls that same function (we'll name that function "Navigate")... however, the function will need to end up doing something different dependant on which button was clicked. So, previously, in AS2, I would've added some code onto the buttons themselves with on(release) methods (see CODE EXAMPLE 1) So, each button effectively calls the Navigate function, and passes a different frame label to the function. Now, I'm trying to recreate this functionality in AS3. As you all know, on(release) has been done away with (still don't know why), but we now have to use event handlers, so I'm trying to figure out a way to pass a different frame label argument to the Navigate function. Currently I can achieve that by using a switch statement to test which button was clicked, and act accordingly (see CODE EXAMPLE 2).

I am working on a game for my university project and I have run into a bit of trouble. I have the following code here:
function launchBall() {
this.stage.addEventListener(KeyboardEvent.KEY_DOWN ,launchBallHandler);
function launchBallHandler(e:KeyboardEvent):void {
if (e.keyCode==32) {
[Code].....
Its set up so that when a ball goes off screen, it resets to a coordinate and launchBall is called.
LaunchBall then adds the event listener to see when the Space key is pressed and that starts the ball moving again. The problem I have now is I cant seem to get rid of that eventListener. I have tried removeEventListener and that doesn't seem to work. I have tried:
if (ball.xVel>0 && ball.yVel>0) {
removeEventListener(KeyboardEvent.KEY_DOWN,launchB allHandler);
just below that code and that doesn't work either. It's not spitting any errors out at me but I am completely stumped.

I just started a course that does a little flash. To teach us they have us build a brick breaker game. I have come to a part were I have to remove all the Listener that were created for the game. Each level is a movie clip and when the level is over the level instance is removed from the child. From what I understand when the level is removed the Event.REMOVED_FROM_STAGE becomes true and the function attached should be called however it is not. Here is the code of the function that sets the listener and the function to be called:

private function myFunction(numIn:Number){
trace ("numIn " + numIn);
}[code].....
This won't work, but can you see what I'm trying to do? It's kind of like a function pointer, or when you pass a function name into an event listener.

I have a method which registers an event listener to each of the MovieClips in an array I have. The method is inside a class, and so is the listener function. The problem is, I'm getting an error that's says "Access of undefined property handleNavToggle", even though is declared.

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 a set of buttons on, and what i would like to do is change the value of a variable, depending which button you are over.i know i could do this by writing an event listener and a function for each button, but this is too time consuming.I'm sure in the old days it would have been as simple as if btnwhatever.mousedown = true then.... but now i have no idea.

I am trying to create an event listener to check that a function has completed before the next action is run. In simple terms I have a module that is opened and closed via two functions... module_open() and module_close().Each function has tween elements that must complete before the next element is processed... i.e the next function, etc.This is the code I have ( have attempted to create an event listener but I seem doing something wrong. I am not even sure that it is possible to create an event listener that checks for a function finishing before calling the next function.
Code:
function onAbout(event:Event):void {
module_close()
module_close.addEventListener(Event.COMPLETE, onClose_Complete);

Say I have the following function
Code:

do some stuff....
}
but i want to call it from the event listener
Code: button.addEventListener(MouseEvent.CLICK,myVideoFunction);
I cant because it runs off a VideoEvent, not a MouseEvent.The obvious work around is to copy and paste the function and rename this part, or alternativly just make a function such as:
Code:
button.addEventListener(MouseEvent.CLICK,callMyVideoFunction);
function callMyVideoFunction (event:MouseEvent) {
myVideoFunction(null);[code].....

The keyBoard event listeners call on the rotate and unrotate functions and based on the key inputs(A and D) will implement either of the functions and rotate the image or return it to the original upright position. However, I haven't been able to get the function to work. When I press the A or D keys on the keyboard nothing happens. I even put trace() in one of the functions to see if the function will even be implemented but I don't get anything. I put in my Scripts below. Why are the functions not working? Do the eventlisteners fire or are there conflicts? I'm not getting any error messages.
ti.border = true
ti.addEventListener(TextEvent.TEXT_INPUT, onInput);
function onInput(event:TextEvent):void {
if(ti.text.search('a')!=-1) load_image("http://i54.tinypic.com/anom5d.png", "ottefct");
