ActionScript 3.0 :: Pass Parameters To An Array Callback Function?
Mar 23, 2010
I'm working with arrays in AS3 and some of the utility functions described in the livedocs such as filter() or some() would be very useful to me, if only I could pass parameters to them...
Actually, I cannot find a single example of the use of these functions with custom parameters passed to their callbacks. Everywhere, it is always used with constants ! E.g. on this page: [URL]
var arr:Array = new Array();var totalElements:uint = 100;for(var i:uint = 0; i<totalElements; i++) { arr[i] = Math.round(Math.random()*100);}function isLargerThan90(element:*, index:int, arr:Array):Boolean { return element > 90;}var highestNumbers:Array = arr.filter(isLargerThan90);trace(highestNumbers);
What I need is a kind of "isLargerThan" function with "90" as an argument's value, not as a constant. Something like
function isLargerThan(element:*, index:int, arr:Array, param:Object):Boolean { return element > (param as Number);}I find it very odd that I cannot find no mention of the way to do this on the whole WWW, because that makes these utility functions absolutely helpless in many many cases and programming with arrays a real pain...

I don't think this is possible, but is there a way to validate the arguments a callback accepts. For example someone passes me callback "mycallback", I want to assert it accepts an argument String.
public function addHandler(handler : Function) : void{
//pseudo code
Assert.functionAcceptsArguments(handler, String);
}

it seems to me that when you use laco tweens and callback a function, you can't pass data in that function, because the function won't wait until the tween is finished but is being carried out right away. For instance, I want to tween movieclip MC:

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.

Here is the code that doesn't work:
Code:

function open(n) {
clearInterval(myInterval);
this["item"+n].play();
}
I have also tried calling a function from setInterval which in turn calls a function with a parameter...also didn't work!

I am attempting to get Flash - Javascript communication working using ExternalInterface.addCallback, using code found at http:[url].... I am trying to pass parameters into Flash using a javascript function, but it only works if I insert a 'window.alert' line into the code. Once I click OK, the parameter str is passed into Flash ok. The function is:
function sendToFlash(str) { if (str=="tools"){ window.alert(str); getFlashMovie("richFunctionality_corp").sendTextToFlash(str);[code]....
If I remove the window.alert, str isn't passed into Flash. Is this a browser speed thing? A value menu is passed out of Flash using getURL("index.php?pageID=239&menu=tools"), i.e. the page reloads and a php script sends the appropriate str value to the sendToFlash javascript function based upon the value of menu.

I have already created a custom mouse event which seems to work fine. It is simply a mouse event which passes an additional sound object. The problem is I am passing this event to another class which checks for collision of a movie clip with another and if true it adds the sound to an array. What I think is happening is a type conversion problem between my customEvent and the MouseEvent. [code]...

I know how to loop through the ...rest param to obtain their values but I'm struggling at how to construct the final gateway.call() which could have 1 arg or 10.

i have one movie clip named one_mc.And i have one function named thisFunction.to add an event listener, i would code:
one_mc.addEventListener(MouseEvent.MOUSE_SOMETHING , thisfunction);
1) I want to show a box containing some text when the mouse is OVER it. Of course, when its not over, the box should not appear
2) I want to give parameters to thisFunction in order to use it, the way i prefer!
I must make one eventlistener for MOUSE_OVER and another for MOUSE_OUT? How do I pass parameters for the function when i call it?

This will work:
Code:
addVolvo.addEventListener(MouseEvent.CLICK, addCar);
function addCar(evt:MouseEvent)
{
[code]...
... but I want to pass the a value when calling the function:
Code:
addVolvo.addEventListener(MouseEvent.CLICK, addCar(classVolvo));
function addCar(evt:MouseEvent, newClass:Class)
{
var car1:Car = new Car( 1, 1, classVolvo)
[code]...
This won't work. Because it then just passes the Class and not the MouseEvent. What should I write in the addCar(...) call function? Ie how to I manually pass an MouseEvent?

I've got a main.as that loads SWF to the stage. the loaded SWF seppoused to pass a link to the main.as and trigger a javascript function to popUp that photo from that link.
I know there are two ways:
((root as MovieClip).parent.parent as Object).somefunction(parameters);
and to dispatch an event. inorder to pass parameters throug the event i need to extend it with another class.
isnt the (root as... ) more efficient if all i need is to pass a link?

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

I am currently doing something like this:
myFunc(tracer);
function tracer(message:String):void{
trace(message);[code]........
Now, this works fine. But how can the function myFunc know, if the given callback function accepts the correct number and type of arguments in its signature?I want to avoid that I call something like this somewhere in my code:
myFunc(tracer2);
function tracer2():void{
trace("done");[code]..........
Is there a way to do something like this, in order to use compiler warnings/error messages and thus avoid exceptions at runtime?
// Won't work :-(
function myFunc(callback(message:String):Function):{
callback("Hello");
}

In AS2 I have several arrays constructed like this :
var myArray0:Array=new Array(value,value,value...)
var myArray1:Array=new Array(value,value,value...)
var myArray2:Array=new Array(value,value,value...)
var myArray4:Array=new Array(value,value,value...)
...
What I'm trying to do is use iteration to reference each array name to pass it into a function.
Like :
function doSomethingWithArray(arrayToPass){
...
}
//Later somewhere in For loop... :
_root["myButton"+i].onRelease=function(){
doSomethingWithArray(WHAT-THE-HELL-I-TYPE-HERE[i])
}

For example:
for(var i:int=0; i<someArray.length; i++)
{
var loader:Loader=new Loader();
loader.load(new URLRequest("http://testurl.com/test.jpg"));
[Code]....
The second paramter (i) for imageLoaded is always 1, I guess because i no longer exists and is defaulting to 1. Is it possible to get that second paramter to be evaluated when the load is started rather than on complete?

I'm making multiple similar calls with similar results to one remote object. Because these calls are so similar and very changeable, I've been keeping the name of the remote method in a config file, and when I need to make the call I use getOperation() on the remote object, and call send() on the operation object. However, the requirements have changed so that not all of the calls will have the same number of parameters. Because send uses ..., will I be able to continue using the same formation and pass an array, or will send() treat that as passing one argument of type array?

want to make a sfw that receives parameters from the html tag. for example, when you embed youtube videos, in the <object> thingy you set the video you want to show. i want to do exactly the same, have a 'projector' (though not exactly videos), the swf knows what to do from the html tag params, and displays the right content. how do i red html params from the sfw (and how do i test it?).
also, is there any doumentation/examples on how to connect php/mysql to a flash movie?
