function fn1(var2)
{
//here i want to trace the name of var1....ie output: "var1"
}
fn1(var1);
how to trace the variable name i am passing to fn1 (ie. var1) as string?
ie. output shoud be
"var1"
ie i want to trace the name of argument variable i am passing
It's too complicate to explain but I'll give you an example
I have an AS3 ResultEvent Object and this object has several propeties which can be accessed by this like:event.result.name or event.result.age and, I have this String variable: eventProperty:String that contains "name" or "age" How do I access to event.result. with the variable?
Is there a way to access a variable via a String? Something like this:
HTML Code:
var myVar1:Int = 1
var myVar2:Int = "myVar1" as variable name
This is obviously doesn't work (and in this case pointless), but is there a way to do this?
Using e4x in flex:
var attr : String = "foo";
var xml : XML =
<resultSet>
<node foo="1"/>
</resultSet>;
How can I use the variable "attr" to access
xml.node.@foo
I thought I could do it with
xml.node.@[attr]
But this doesn't seem to work. How can I access this attribute by a dynamic value like this?
Both
xml.node.@[attr];
and
xml.node.attribute(attr);
work, as Constantiner suggested.
Updates:
Say I have an XMLList in this form:
var bar:XML =
<resultSet>
<node>value</node>
</resultSet>;
I want to filter the original xml above by matching "foo" attributes with the "value" from node in bar.
Essentially I want a sublist of the original xml such that
xml.node.@foo == bar.value
for each xml row in the original value
As Constantiner mentioned, I can filter the original list by the value in foo, but what if I want to filter on multiple values?
Can I do something like:
xml.node.(bar.node.contains(attribute(foo)) ? attribute(foo) : null);
Or perhaps a cleaner method instead of the null?
my goal is to keep my output window organized so i can follow all my traces more easily. so i wrote a couple of custom functions to achieve that. one of them would be: to more easily trace the following variable for example

f you know PHP...then you know that you can create a string variable...and then use the value of that variable to declare another variable. like this:
PHP Code:
<?php$foo = "haha";$i{$foo} = "success";print $i{haha};?>
and it would display "success"...or like this:
PHP Code:
<?php$foo = "haha";$$foo = "success";print $haha;?>
and it would also display "success".
I have a String variable in my flex (flash builder 4) application containing CSV data. I need to allow the user to download this data to a local file. For example, giving them a "csv" button to click and it might present them with a save file dialog (and I would be sending the contents of my string variable).Is this possible / how ?I am using the ResuableFX component for the datagrid to csv. This the code I ended up with that works to save the string to a text file for the user (in a web browser):
var dg2CSV:DataGrid2CSV = new DataGrid2CSV();
dg2CSV.includeHeader=true;
dg2CSV.target=adgEncounters;

If i have an ASP page that is returning variables (and I can see them in the debugger) how do i consentrate a string to call that variable?

Trying to replace a portion of a string with a "-" if it matches a string variable in AS3.
var re:RegExp = new RegExp(imageArray[j][1],"gi"); trace(imageArray[jTemp][2].replace(re,"-"));
imageArray[jTemp][2] is a string imageArray[j][1] is a string as well I'm not getting the result I expect. I would like trace above to return 'permanentContainer-' Here are the traces for the above variables
permanentContainer-temporaryContainer- temporaryContainer
how you would target a function's local variable through a concatenated variable string.For example:
var txt = "Hello World";
function testing(msg) {
var test1 = msg;[code].........
I'd expect the trace to be "Hello World" but rather is given "undefined". So if variables created outside functions are created on the main timeline, where are local function variables created and how would you access them?
i'm getting a value from a class that gives me e.g "icon1" as data. i want to use this within a function to control the visibility of an item nested in a movieclip on the stage. the nested movie has the same name as the data being sent.
// here's what i want it to do:
mymenu.icon1.visible = true;
// but i cant append the 2 together as flash will see it as a string not read it as path.

I have been banging my head against a brick wall regarding the following problem which must be very simple to fix, just can't see the answer.I have a class assigned to a movieclip called canvas. The class is called drawClass. I have called the instance of canvas on the stage 'drawingCanvas'.When I trace "drawingCanvas" I get object drawClass] which is fine. Tracing drawingCanvas.name gets me the instance name 'drawingCanvas'.This is a String variable.Basically what I am trying to do is pass the MovieClip name to another class. In my example the class 'toolBar', which can then interact with the MovieClip.
The problem is passing 'drawingCanvas.name' results in a String, so I get an error saying :TypeError: Error #1034: Type Coercion failed: cannot convert "canvasArea" to flash.display.MovieClip.I can't for love or money find a way to convert a String variable to a MovieClip variable! I have the name of the MovieClip, I just need to tell the toolbar class. But I can't find a way of doing this as the instance on stage is an object of drawingClass, not a MovieClip (unless MovieClips with attached classes are not treated as standard MovieClips?).
This is sort of difficult to explain but I'll do my best. I've got 6 score variables that go up over time.
[Code]...
Each corresponds to a different color of "Monster" class I reated. "GreenMonster", "BlueMonster", etc. are all custom classes. Each class has a string property called "MonsterColor". So "Blue1.MonsterColor = "Blue".
To save lines of code, and learn, I'm trying to use a local string variable to take the place of whichever of these 6 int variables I need. So inside a for loop, I've created a variable called "colorscore".
[Code]...
I would like to dinamically create array variables, depending on a XML file. The problem I have is that I don't know how to create them dinamically using a name I have constructed into a string variable. What I would like is something like this:
var strVarName;
...
strVarName = "Var" + i;
var strVarName = new Array();
...
So I would have n arrays called Var1, Var2, ... Varn.
How can I access the member variable of an object by using a variable in the name.Example:
Entries Object has properties 1, 2, 3, 4, 5.
Normally I would access them by
var i : int = Entries.1;

In AS2, you used to be able to access an array using a string variable by putting it in [].[code]...

I was trying to make a menu for a game, (and I succeded, it works fine) when I noticed that if I store a clip name in a string var I can't I acess it's alpha with varName._alpha (?) or some other ways I tried.
Is there anything wrong in my code, or is there a way to do it that isn't the one I'm trying?
The way I'm doing it, I have a MovieClip for each screen, that in turn contains all the MovieClips and Buttons, etc, that each screen must contain. So sometimes I must specify the path to things with "_root.MovieClipName.thatThing._blah". Although I think this has nothing to do with my problem there, since the vars are all declared in the stage's timeline...
If you don't quite understand how the functions work, here's a call swapScreen function example: swapScreen("overlap", "OptionsScreen", "options");
If "swap", it removes the screen I'm in, and attaches another one in place. If "overlap" it overlaps the current screen with an overlaper screen (like opening the Options menu ingame). restoreScreen() restores to the previous screen that has been overlapped.
ActionScript Code:
function swapScreen(swapType:String, ID:String, screen:String):Void
{
if (swapType == "swap")
{

Now one of the functionality that's added to the player is the "Transcript Button", which shows subtitles in a small window.Well, what I've done is added text on keyFrames of the main timeline,so if the audio says "Hello good evening, welcome,....", I've made a new layer above the audio layer and during that particular part of audio I've added the text on the new layer in a keyFrame.I've done this for the entire timeline.I've used enterFrame and accessed this String value and displayed it in the small window.Everything seems to work well.But if a certain movieClip popup is added on the timeLine, which has its own audio.o necessarily I'll have to add the text to this movieClip as well, but I cant access the text, i.e, display it in the small window.Also I've tried using a global variable like this,...

I'm trying to create a quick access to a object with a String as it's key, so I wrote:
"var map:Object = {};
map["key1"] = object1;
map["key2"] = object2;
..."
Is there any difference about the performance between long key and short key(the length of the String used as a key)? If the key contains many charactors, will it slow down when accessing that object?
I'm developing a compiler generator in actionscript 3 with flash builder 4. I need to find a way to:
1.- Execute code inside of a string.
it could be very complex code, not just trace() functions but complete code
2.- Another alternative can be to tell to the actionscript compiler to compile the code autogenerated from my compiler generator.
