Flex3: Custom Item Renderer does not listen to events dispatched by parent

I have a List with a custom ItemRenderer. The ItemRenderer contains a Checkbox and a Label. The component with the List has a 'select all' checkbox. When the 'select all' checkbox is checked, it dispatches an event that each item should listen to in order to select its own checkbox. The eventlistener is added on creationComplete of each ...

Retreive a list of Events

Is there any way to retreive a list of events of a DOM in Javascript? e.g. I register FuncA, FuncB, FuncC for the onclick event using AddEvent or AddEventListener methods. How do I get the reference of all these functions for that onclick event? Ideally, I want to have a function like this: eventList = getEvents(obj, 'onclick'); a...

ActionScript 3.0 current function called, plus all the previous ones somehow

Alrighty, I don't know how I did this, probably the AS3 gods became angry with me when my scrollbar worked right after I coded it, with no bugs. But I have a very weird problem. I have three different buttons, they aren't nested within each other, and they have event listeners for mouse clicks that call a function. Whenever one of these ...

Form is still submitted even though listener function returns false

I'm trying to figure out why this JavaScript doesn't stop the form from being submitted: <form action="http://www.example.com" id="form"> <input type="text" /> <input type="submit" /> </form> <script> var code = function () { return false; }; var element = window.document.getElementById("form"); if (element.addEventListener...

Javascript - How to detect if document has loaded (IE 7/Firefox 3)

I want to call a function after a document loads, but the document may or may not have finished loading yet. If it did load, then I can just call the function. If it did NOT load, then I can attach an event listener. I can't add an eventlistener after onload has already fired since it won't get called. So how can I check if the documen...

addEventListener & wmp not working as expected

Hi, I have a WMP player object and I'm trying to add an event listener to intercept ScriptCommands that are sent to the player. Instead of being attached to the WMP object, my callback is being called right away, and then the ScriptCommands aren't being intercepted. function init() { var WMPlayer = document.getElementById("WMPlay...

AS2: How do I use addEventListener on an SWF/MovieClip loaded via MovieClipLoader

I'm trying to load a local SWF then catch a few events that are fired but I can't see why this isn't working. Here's the code Parent.swf _mcl = new MovieClipLoader(); _mcl.addListener(this); _mcl.loadClip("Child.swf", rotator_mc); function onLoadComplete(clip) { clip.addEventListener("initAsLoaded", function() {trace("childLoaded...

Dispatch Event When Listener Is Added - ActionScript3

Is it possible to dispatch an event from an object when an event listener is added to that same object, without overriding the addEventListener method of that class? I am working on a modularized application in AS3. Several of the modules register events on a component in the main application mxml file. I would like to fire an event...

Passing parameters to event listeners / handlers

How do you pass parameters / variables through event listeners? I've overcome this problem fairly effectively using anonymous functions; which is an incredibly simple solution, but at the end of the day, it smells like a giant loophole for functionality that I feel should be provided natively anyways. Normally life would go on, but as f...

Best Practices for Suspending Buttons in Actionscript 3

Ok, so my first question here was so well answered I figure I'd try my luck at this little query. Is there a better way to set up a flash project with lots of navigation than having to do this?: bottomNav.contact_btn.addEventListener(MouseEvent.CLICK, changeContent); bottomNav.portfolio_btn.addEventListener(MouseEvent.CLICK, changeCont...

addEventListener() question/weird behavior

I'm developing a game for Facebook. I'm using PHP and FBJS. I'm using addEventListener() to attach events to two buttons. Each button has it's own event handler which is a js function. The first event handler (loadNewCargo()) gets called with no problems. But the second event handler (discardExistingCargo()) causes the page to refresh wh...

addEventListener() attached to multiple buttons, but only fires once

I am writing a Facebook app in PHP/FBJS. I have some code where I attach an addEventListener() to two buttons. When I run the app, the first button I click on fires the addEventListener() and the event handler is invoked as expected. But if I click on the second button or click on the same button again, the event handler is not invoked. ...

addEventListener only works on last object.

In the following code, it seems I only get the 'otherboxclick' call for the last box added (b1). If I change the order the boxes are added, it's always just the last one that works. How can I get it to work for all the boxes? <html> <head> </head> <body> <script type="text/javascript"> function otherboxclick(e){ alert("other...

MSIE and addEventListener Problem in Javascript?

document.getElementById('container').addEventListener('copy',beforecopy,false ); In Chrome / Safari, the above will run the "beforecopy" function when the content on the page is being copied. MSIE is supposed to support this functionality as well, but for some reason I'm getting this error: "Object doesn't support this property or ...

AS3: Faster to use EventListeners or ArrayLoops?

I am writing a game in AS3 and have, as an example, around 40 objects on screen. Let's say they are clouds. I'm wondering which of the two paths would be less a strain on system resources: a) Put an eventListener on each object and have it update itself, or b) Loop through the array and manually update each object Or is the performanc...

onmouseover doesn't work when using javascript to add img tag on IE

I need some javascript code that dynamically adds an img tag to a div, and the img tag needs onmouseover and onmouseout handlers. I have it working on Firefox. But it doesn't quite work on IE.
