ActionScript 2.0 :: Send Parameters To Another Function Through AddEventListener?
Nov 21, 2006
Here I've got this bit of code that works alright, but I would prefer to have the parameters that are being sent through myTween.tweenMe(_text, 40, 300, 150, 100, 4000) originate instead with the call to tweenerIt. The problem seems to be that the tweenerIt function needs to receive the e:Event parameter, which is some sort of 'behind the scenes' type of thing that I don't fully understand. If I try putting ... _text.addEventListener(MouseEvent.MOUSE_DOWN, tweenerIt(_text, 40, 300, 150, 100, 4000) and then something like.. private function tweenerIt(param1, param2, param3, etc..., e:Event):void, it doesn't work.
Code:
_text.addEventListener(MouseEvent.MOUSE_DOWN, tweenerIt);
}
private function tweenerIt(e:Event):void {

i have couple of videos that i want to play in succession. my theory on how to do this was to add an event listener that would call function to change the source of the FLVPlayback component and play once the initial video finished playing. The problem is that i don't know what parameters to pass to the eventlistener and the acting function. I just need someone to fill in the blanks to the following code

So I have an MC that has 6 labels and 6 buttons all with different names. When you click on a button, it needs to direct you to it's appropriate frame label in the MC. Now, since AS 3.0 has done away with inline functions, how the heck do I code it so I don't have a function with a bunch of if statements inside of it in addition to all of my eventListeners that I have to add to each of my buttons? In AS 2.0, I would have done it like so:
Code:
function movePlayhead(whichOne:String):Void{
this.gotoAndStop(whichOne);
} button1_mc.onRelease = function():Void{
movePlayhead("label1");
};
button2_mc.onRelease = function():Void{
movePlayhead("label2");
};
Etc...
With AS 3.0, you have to add eventListeners to each of your buttons where each eventListener calls a function, but how can I write it so I don't have to write a bunch of if statements inside the function the eventListeners are calling in order to test for which button is being clicked? Like so:
Code:
button1_mc.addEventListener(MouseEvent.CLICK, movePlayHead);
button2_mc.addEventListener(MouseEvent.CLICK, movePlayHead);
button3_mc.addEventListener(MouseEvent.CLICK, movePlayHead);
function movePlayHead(event:MouseEvent):void {

I've been browsing lots of forums lately regarding the issues involved with passing parameters into functions called by event listeners. I think I may have come up with a good solution using anonymous functions but I'm not sure yet if its "safe" to do.
Code:
this.addEventListener(Event.ENTER_FRAME, function(e:Event):void {
myFunction(e, arguments.callee, "hello")
});[code]....
The code prints "hello" once, which is what I wanted. I believe I have deleted the anonymous function, but I need some thoughts from those who may be more knowledgeable about flash garbage collection and such to be sure.

I am trying to work with a simple HTTPService. The problem is that my webservice is conscious of the order of arguments it gets. I will tell the problem with an example:
var service:HTTPService = new HTTPService();
var params:Object = new Object();
params.rows = 0;
params.facet = "true";
service.send(params);
Note that in the above code I have mentioned the parameter rows before facet, but the url I recieve is facet=true&rows=0. So I recieve the argument rows before facet and hence my webservice does not work. I figured out that the contents of array is always sent in alphabetical order, which I dont want.
Is there any way I can achieve explict ordering of parameters sent?
Note that I am not in power of changing the logic of webservice(its basically a RPC service supporting both desktop and web client).

I am trying to populate a component combo box using an urlloaded xml, the xml has been "escaped" and the spaces replaced with +.
How do I populate the combo box as when I unescape the xml and replace the +s it is now in string format.
When I have the combo box in need to be able to select an option, which reflects in the next urlrequest...e.g.
TextLoader.load(new URLRequest(" http://onedev/one/Query2.asp?Cat=THEvalueFROMmyCOMBOBOX "));

I'm having some trouble passing parameters with a function that is itself being passed as a parameter.In my application code I'm instancing that class five times:they are buttons in a menu.In that class, I've got an onRelease handler that does a number of things when a button is released, one of which is to invoke a function that is defined in the application level of the code.My problem is that I don't know how to send the function parameters.In my StandardButton class I have:
class StandardButton extends MovieClip
{
/* define properties */[code]..........
The function is successfully being "sent" to the StandardButton class, but without any parameters.How can I send parameters to the class instance with the way I've got this architected.

I have 2 methods in a class and 2 properties. The first method fetchXMLData() gets data from an XML file. In the addEventListener method on the urlLoader object, I pass it a listener which tries to set the returned data to the xmlData property. However, it never sets it, and I know the data comes back because I can alert out urlLoader.data using the mx.controls.Alert component.

I'm working on tabs that display different carousel type galleries with previous and next buttons. So, I've got a function that is being called by these tabs and is passed an array based on which tab is selected. Inside of that function, I'm adding an eventListener to the previous and next buttons and using a callback function that works based on the number of items in the array that was passed through the function call. I was running into some strange happenings and using trace statements. Here's what I find: The first call to the function works and traces correctly. The second call traces 2 trace statements; the 3rd call traces 3 statements and so forth. So, I'm assuming that each call is adding another event listener to the buttons.
Here's a condensed version of the function in question:
Code:
Select allfunction loadgallery(picArray){
/* Image Loading code here */
var totalPics = picArray.length;
var picNum = 0;
next_button.addEventListener(MouseEvent.CLICK, nextPic);
function nextPic (e:MouseEvent):void{
picNum++;
/* Tween actions here */
trace("picNum: " + picNum); //this traces 1x first time, 2x second, 3x third, etc.
}}
Do I need to remove the event listener from the next_button? If so, what's the best way to do that? Or does someone see something else that I"m overlooking? I tried removing the event listener at the beginning of the function, but failed.

I am trying to figure out a way to be able to trigger an event which will display a message. The only thing is that the date function does not seem to be equipped with the ability to set events to it. I read the reference to it on the Flash support site and it seems as it is usually only used for date stuff.
I downloaded a digital clock, but it seems as that is based on diffrent principals as it was simply iterating throught the if stmts

I built a custom designed checkBox. The movieclip is in the libary and dragged onto the timeline of my .swf. I'm using CS4 & AS3. I'm using procedural AS3 instead of OO AS3.The checkbox movieclip has a child movieclip inside of it so I can apply a drop shadow filter to some of the graphics .When I put an eventlistener on the custom checkbox it works fine but when I try to reference the checkbox movieclip inside the eventlistener function, the event.target.name is referring to the child movieclip (just a graphic with a drop shadow filter).From my reading it looks like the function propogates down to the child movieclip but I don't want it to do that.How do I reference the parent movieclip? or
B. stop the eventlistener from propogating down to the child movieclip?
I tried using stopPropagation(); but it didn't stop the function event.target.name from trickling down to the child movieclip.Here's what AS3 looks like.The trace statement displays "step3_mc.cbEmail_mc.instance25"instead of what I need "step3_mc.cbEmail_mc"
step3_mc.cbEmail_mc.addEventListener(MouseEvent.CLICK, fnc_cbClick);step3_mc.cbAgree_mc.addEventListener(MouseEvent.CLICK, fnc_cbClick);

I have preloader code in my main FLA, and I load the corresponding preloader (a small file) externally. When I detect that the file is fully loaded, I need to add the listener to the content that I want to "preload".[code]If I use it this way, the loaderInfo listener does not work, but if I add the listener ouside of the handler function, it does.The problem is, I need it to work from within the complete handler, because obviously, the preloaded can show the % completed only after it's loaded...

I got this weird problem, when i run this code:
Code:
package {
import flash.display.MovieClip;
[Code]....
In Flash Cs3 it acts exactly as i want, the ENTER_FRAME runs and the addObject places numerous sprites on the stage. In the window output i'll see the trace. But when i run this code in Eclipse which is set up to use the Flash Player as output i get the first trace from EDHV_ImageSlider but the traces inside addObject won't show up, the sprites however are generated perfect.
The difference between the eclipse setup and the cs3 setup is the fact that the cs3 setup has a *.fla which calls the *.as package.
