It is possible to call variables using this[ "stringname" ] for instance, to refer to a variable called "stringname".
However, when referencing a static variable by the name "stringname", the "this" attribute no longer works if applied.
Is it possible to use this technique with statics?
I'm wondering if its possible in flash to be able to call a static class function via its name as a string. I know for you're usual case you can do this to call the function 'func'
Code:
this["func"]();
func():void
{
trace("I'm a function");
}
However I'm wanting to do this from another static function and in a static function you obviously can't use the 'this' keyword. I've tried just omitting it, or replacing it with the class name but neither work.
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?
ie:
variables being returned are named:
"res1", "res2", "res3"...etc
for (var i = 0; i < 10; i++) {
[Code]...
How do i go about this,
Lets say i have a variable _a:Number=5 and _b:String="_a"
I want to call a variable whose name is contained in _b
I need to call an object or function name with string variable.[code]it's working but, if I do something like below its not working [code]
View 2 RepliesTrying to replace the number on the following call with a variable... How could i do it? Have to remove 144 of them... rather do a loop for it...
Code:
_root.mc_movies_area.mc_area_54.mc_54.removeMovieClip();
Does anyone know if there is a way to call a dispatchEvent call from inside of a static function?
View 2 RepliesThe Idea is i want to make avariable that stores his value after i close the swf and open ti again,
an example:
i make acounter
var i:int = 0;
var timer:Timer = new Timer(1000);
timer.start();
[Code]....
the value of i will increase but after i close the application and open it again the value will return to 0 , keep the variable stores his value after closing the application ?
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".
Is it possible to call/envoke a public static function from JS? I can't seem to get it working and Im almost certain it cannot but I thought I would ask the community.
View 2 RepliesI 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;

I have a pointer to a Class object like so:
var temp_class:Class = getDefinitionByName(getQualifiedClassName(some_obj ect)) as Class;
I want to use it to call a static method 'can build' on that class, like so:
function can_build_ot(c:Class, qualifier:Object):Boolean {
if (c.can_build(this, qualifier)) {return true;}
return false;
}
When I do this, Flash CS4 AS3 tells me
1180: Call to a possibly undefined method can_build.
I found a lot of tutorials that show how to use getDefinitionByName() to create an instance of a class. Something like the following:
Code:
var classRef:Class = getDefinitionByName("menus.buttons.Icons") as Class;
var iconClassInstance:Icons = new classRef() as Icons;
[code]....
I am trying to set the value of some static vars but I need to reference the class with a string rather than a proper constructor. In AS3 I can do this with:
var ref:Class = getDefinitionByName(classDefinitionAsString) as Class;
ref[varNameAsString] = newValue;
I can't find an equivelant approach that will work in AS2 though. I have tried:
var ref:Object = new [classDefinitionAsString];
ref[varNameAsString] = newValue;
This seems to just create an Object and as the vars that I am trying to access are static I don't really want to be using 'new' I just want to reference the vars.
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

I have two Cairngorm MVC Flex applications (a full version and lite version of the same app) that share many Classes. I have put these Classes into a Flex Library Project that compiles as an SWC. Both applications use some static String constants. Right now, I am storing these in the ModelLocator:

View 2 Replieshow 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 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?).
