ActionScript 3.0 :: Simple Parameter Passing On Event Listener?
Oct 11, 2009
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 am a n00b and therefore might get terminology etc. wrong. I am developing for Scaleform (therefore authoring in ActionScript 2.0 for Flash Player 8).
I have a movie clip on stage which is a stack of buttons. I want to create a simple test, I want a function to fire when the mouse is rolled OFF the BtnList movie clip.

I am having trouble getting a simple event listener class to work. The class is:
Code:
package {
import flash.display.Sprite;
import flash.events.*;
[code]...
and I have the ClassPath pointing to the folder that contains this .as file. I do get the trace "In setUp" but I'm not getting seeing any Keyboard events. There also aren't any errors showing up in output so I am kind of stumped.

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 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.

Forgive me for this stupid noob question but I want to call a function (loadList) that originally gets triggered after a mouseevent from another function (addToXML) that does not have an event.
The loadList function takes info from a XML var, sticks it into an array which then gets loaded into a tile list and that is working fine.
The addToXML function when called adds elements to the XML var after which I want to call the first function with the event parameter so it refreshes the items in the tile list.
I know it can do this by creating a new array and loading that into the tile list in the addToXML function, but it be much simpler to just recall the function.
I have tried things like
Code:
addToXML.addEventListener(Event.COMPLETE, loadList);
but all the event constants I have tried give me error messges like "1061: Call to a possibly undefined method addEventListener through a reference with static type Function."

Can't figure out why I'm getting this error:Error #2007: Parameter listener must be non-null. I have traced the xml, so I know the values are loading, so don't know why I"m getting a "non-null" error.The first value in the xml traces correctly, but then the error occurs.I only receive the error when I pass the popup argument to createImageHolders, and I don't know why... I"m a 3.0 newb.

import flash.events.MouseEvent;

We are getting ready to start trying to convert our older content to AS3.To this end, I have been trying to develop what I though would be a relatively simple. It just an attempt at an adaptable mc button class that my animators and designers can kind of "plug and play" so I can spread out some of the workload.I keep getting "Error 2007 Parameter listener must be non-null". I understand why its throwing an error. simplified block:

I'm trying to pass an mc instance as a paramter of a function. is this possible because I keep getting errors.
Code:
function moveCircle(sIncrement:Number, sMovie:String):Void {
sMovie._x +=sIncrement;

I'm trying to do this to cut down on redundant functions I've used in the past for simple as movements and controls.

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.

i have 1 PHP page in which i have a Flash animation. this flash swf file, display 2 fields and 1 button.
this php page is called "test.php".
i'm able to send data from Flash to a PHP page, but i would like to send the content of those 2 fields to the "test.php" and display them. however, i do not know how to do it.
i see that it works but i'm not able to display or refresh the PHp page to display the result.
as walkaround i was thinking to collect the webpage address where is executed the flash and to send it to another PHP page. and this 2nd PHP page, will reload the test.php with parameters...
how to get under flash, the address of the actual executed php page ?
