Actionscript 3 :: Javascript Approach To An Associative Map With Objects As Keys?
Dec 16, 2011
I'm looking for the javascript way to an associative map/array/hash that's using objects as keys. A replacement to what you can do in ActionScript 3 with the flash.utils.Dictionary. I'm sure java and C# have something like it too.It'd work same as a normal generic Object based assoc[key] but instead of string-based properties you use whole objects as keys (it will match not on toString() like Object does but on unique instance). Very handy to decorate objects you don't own (by using the object as keys and your decorations as value).[code]Main point of issue is I need to match on object only (it's being used by some other process you're not to interfere with but we still need association). So no magic .__hash props or toString() overloading (if possible).

I am writing to ask if there is anyone on the list tried to find out the index of elements of an associative array.
[Code]....
See, these are all part of regions array, which I believe is an associative one by the way I constructed it. I tried to use indexOf to find out the index of the individual elements, but don't seem to have too much luck.
ActionScript Code:
for (var s:String in regions) trace("
" + indexOf(s));
Right now, this does not bring me a thing. Have I done something wrong here?

I have a multidimentional array already made, brought in from a CSV file via csvlib.I also have the headers in an array and I would like a way to assign this array as the keys for the arrays.here's a simplification. have a data array like so
data[0] -> [0] blue, [1] 1984, [2] wednesday
[1] -> [0] green, [1] 1926, [2] friday
and a simple array of keys/properties (header array) like so:
[0] colour, [1] year, [2] weekday
I'd like to insert the keys to make
data[0] -> [colour] blue, [year] 1984, [weekday] wednesday
[1] -> [colour] green, [year] 1926, [weekday] friday
i've read up into associative arrays a bit and am not getting how to do this. (there's 38 properties so remember which is which is going to be quite inconvenient).I sort of thought csvlib would do this automatically but it appears the headers just exist completely independently.

If I have an associative array, say, cars = {make: "Honda", year: "1997", model: "civic"} is there an actionscript function to retrieve just the keys, (namely make, year, and model)? If not, how could it be efficiently done?

I have an array of objects which uses a delimited string as the keys. When examined in the FB4 debugger, the keys look like this:[code]The first two items are numeric (cast to string) but the third item in the multi-part delimited key is naturally a string -- it's like an alphanumeric library shelf reference. As expected, when you click on the [+] icon in the debugger, you can view the object associated with that string key. So far so good.The debugger shows the keys in the (pre-sorted) order in which they were added to the array. However, when iterating the object array so:[code]the keys are returned in some other order --internal hash? My question is, how does the debugger know the order the keys were added in, and can I access that knowledge at runtime when iterating the array? I want to iterate the objects in the order in which they were added. Or do I need to maintain my own index of these keys showing the order they were added to the associative array?

I'm trying to send an object to javascript that can have an arbitrary number of elements included, including associative arrays. If I create the following object:[code]The numeric indexes of the array will trace out, while the string based indexes will not. Does anyone have any idea why this might not be working? (Running CS4, I can't find the option to change my signature)

I have had a long post somewhere on here and just wanted to start a specific post on just associative arrays. First of all I have an array which I don't know if it's an array or an associative array or an object or both. ie: I read that the below would be an object but works as an array too.
The problem is when I use this array as references to instantiate classes in a runtime shared library.I seem to be able to create the appropriate arrays and objects BUT I definately can't use/acess them properly. I massive confusion between movieclips and objects. I get a forced conversion error when I try to add objects to a movieclip . simply because I want to add the mc elements to the stage.

I am trying to use Javascript to intercept keyboard events, so I can do CMD-W for "close-window" and whatnot, inside a Flash application, so the Browser doesn't get to use them. Well, I am able to listen for ALT, CTRL, and CMD onKeyDown/onKeyPress events, but I am not able to listen to anything else...
Here is the code, in the index.html file from a Flex Project:
<script language="JavaScript" type="text/javascript">
document.onkeydown = function(event) {applicationKeyboardHandler(event)}
document.onkeypress = function(event) {applicationKeyboardHandler(event)}
function applicationKeyboardHandler(event) {
alert("Key Pressed")
} </script>
I would like to make it so it could listen to any key press, not just alt/ctrl/cmd.

The following doesn't work (although it gives no explicit error), but why not?nd... Is there really no way around it, strictly using the with statement? Forget using for / foreach.
with (object1, object2) {
attribute = value;
method();
}
Why the code above gives no syntax error, doesn't work but is accepted by with?If it's possible, how could we change multiple objects with same attribute using with?
var object1 = { attribute: 3 };
var object2 = { attribute: 2, method: function() { alert('blah'); } };
var object3 = { method: function() {alert('bleh'); } };

whether using a String as the key in a Dictionary results in slower lookups than using an Object, Class or Custom Object (an instance of developer defined Type)?
When using a String as a key, does the literal String have to be parsed, or does the Dictionary key point to the String Object?

Is it possible to pass native JavaScript objects such as arrays and hash-map-like objects to Flash Player with SWFObject?
I basically need to pass an array of objects to Flash from JavaScript in the Flash variables, so this is my code:
[Code]....
When I get the object in Flex, I simply get a String that looks like this: "[Object object], [Object object]" which leads me to believe that my array is being serialized into a String before entering Flash. Is there any known workaround?
And yes, I do need to pass Flash variables in this manner, since they'll key off some loading which is necessary to do before the application starts.

Is there any way to mute other flash objects on the same page with ActionScript or Javascript? I can understand if this would be a security issue but my flash does have a user-initiated mode which takes over the screen and I was hoping this might be an exception where it's clear it has full priority for the user.

The intent is to implement a zoom effect for my photo gallery where photos are displayed at a default size when looking through them but if clicked they will zoom/scale up to a larger size for a more detailed view of them.I've attempted to do this by loading the jpg at it's full size when zoomed, having a Bitmap draw it, then immediately scale down the Sprite container that holds it. I call this scaled down version the default size. When the user clicks on the Sprite shown at it's default size, it is scaled back up to it's original size using a tween to give it that growing larger zoom effect. I call this larger unscaled version the zoom size.
The problem is with the default size (scaled to .66). It is not very sharp and has a noticeable lack of detail. I've compared the quality of it to a smaller jpg (equal display size) of the same image and the smaller unscaled version looked way sharper. I have set smoothing = true; so the tween responsible for the scaling will appear smoother. The tween looks perfect and so does the zoom version. The default version of the image when it is not being tweened is what looks bad

I am not very code oriented, but I found this code that I altered for my needs, and it works, as you move your cursor towards the bottom of the screen the movie clip fades in. However, in addition I need one that does the inverse where another mc fades in as you approach the top. Does anyone know how I would acomplish this task?

I've created a jQuery plug-in that allows a selected panel of a web page to be pinned to the top of the browser view-port when the user scrolls a long page after passing a particular horizontal point on the page.When the panel is pinned or unpinned, a strange thing occurs: if a Flash SWF object is present as a descendant element of the container, the Flash object either restarts its animation or disappears completely.The pin or unpin change occurs when the CSS property "position" switches between fixed, absolute and static. This forces Firefox to redraw its elements and it causes the <object> to reload and reanimate the Flash movie. I read this post with interest:URL...
Does anyone know of a workaround that prevents the <object> tag from reloading? I admit the Flash is an ad, but this problem only occurs in Firefox. Although there are suggestions that this may be a bug, I have searched without success and I'm scratching my pate with a deadline fast approaching.

I come from game programing using c++ and glut (which is an external library to display sprites and stuff). in glut you do everything in the code there is no drag and drop, this is nice since all the control is at the code itself, this is also annoying because when you want to display something you need to guess the right coordinations, this requires a few tests until you get the right coordinations.
Now in flash you do have the drag and drop feature which is great but it doesn't go well with the OOP concepts, at least for me.my dilemma is: do you create your frames (symbol creation and placement) by code only (but miss the drag and drop freature of flash) or do you create pre-made frames by drag and dropping symbols from the library?

Our game is a bird-eye view game, with a dark atmosphere. The player carries a flashlight which can be used to brighten up the environment.So far, we've tried using masks, and although it works, it's not very effective. Every object needs a seperate mask, it tends to use a lot of CPU and is generally a mess to work with.I've considered using a system of black tiles at 90% alpha all over the room, which change their transparancy when the player moves near - but I was unsure.

And set function A1.startDrag();The problems which i have now is the handling of the mouse events. Because Flash was bussy with movieclip A, and is now interrupted by movieclip

make moviclip 1
set location A1 under the mouse cursor
