Is there, uh, a way to use the value of a string to reference a variable name?
I'm trying to dynamically assign XML node names and attributes using a string value, I tried something like this:
Code:
var sItem:String = "book"; // to be dynamically assigned
for (var i:uint; i < _xml.book.length(); i++) {
aList.push(_xml.(this[sItem])[i].@title);
[Code]....
I want to reuse these two functions for about 10 items that need to be dragged and dropped. I need to reference 10 Boolean variables on the main timeline by building strings in the functions to make up the Boolean names so I can reuse the functions. Check the coded in red. [URL] Fla is above
[AS]
stop()
var startX:Number;
var startY:Number;
[Code]....
So i have an external text file organized like this:
/* $file: data.txt */
&title0=Sacrum
&detail0=Detail text for Sacrum
&title1=L5
[Code].....
There are 28 of these 'title' and 'detail' pairs. The 'title' text is to fill a dynamic text box and the 'detail' to fill another dynamic text box depending on which section the user is mousing over.
My issue is getting the text from the file stored into arrays. For my test loop I keep getting undefined as the stored value, and i know it has something to do with converting a string value to object..
var lv:LoadVars = new LoadVars();
lv.onLoad = handleDataLoad;
lv.load('data.txt');
function handleDataLoad (success:Boolean) {
[Code]....
f you know PHP...then you know that you can create a string variable...and then use the value of that variable to declare another variable. like this:
PHP Code:
<?php$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;

How do I reference the variable pointed to by the variable text but pointed to by more than one function?Say I have:
engine_level = 5;
tank_level = 3;
v_name = 'engine';
[code].....
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 reference the variable pointed to by the variable text?
Say I have:
engine_level = 5;
v_name = 'engine';
pb_name = v_name + '_p_button'; // so pb_name = 'engine_p_button';
level = v_name + '_level'; // so level = 'engine_level';

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.
[Code]....
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?).
I've got a set of arrays being dynamically generated with paths to nested movieclips. The paths are coming in as strings, and I can't seem to get them to work as movie clip instance variables.as example, a string would be:
siteMC.b1MC.b1f1MC.rMC
(that path works fine outside of the array)
How do I get that kind of nested path from the string to something flash wont spit out as null?
I cant get the this[] keyword to work. I want to send a string to a function and then, via the string reference a Sprite. Are theire any other ways to adress a sprite with a String value?I thought this[myString].alpha = 0.5; was gonna do the trick but i keep getting (1010: A term is undefined and has no properties.). I tried every possible solution it feels like. Delaring Strings locally and Global...but i can�t get it to work.
PHP Code:
//Nothing Worksthis["myString"].alpha = 0.5;this[myString].alpha = 0.5;//Anyway to reference a Sprite with a String?
is it possible to create a new reference to an array by using it's varname ?
e.g.
private var _myArray:Array = new Array("a","m","d");
...
function getReference(_varName:String):void
{

I'm trying to refer to a specific XML node dynamically. Is there any way to convert a string to reference properly? Or is there any other way?
So I want to be able to write...
Code:
trace(myXml.fruits[1].name);
...but have the "fruits[1]" stored in a variable so it can be changed easily. It might look something like...
Code:
var special:String = "fruits[1]";
trace(myXml.special.name);
...but that doesn't work.
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.
I'm wondering, and hoping, if I can access and use a specific instance of an object if I only have the name of the object instance in a string? The code below perhaps explains it a littler better.

How to convert sting to structure?
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.
I'm trying to keep my code succinct by naming my section labels the same as the buttons that navigate to them. I've also put the contents of each page in a movie clip of the same name with suffix _mc. The following code successfully traces the name of the movie clip, but how do I tell the compiler that I want to reference the movie clip whose name is held in the string, rather than the string itself.
function clickSection(evtObj:MouseEvent):void {
currentContent = currentLabel + "_mc";
trace(currentContent);
currentContent.alpha = 0;
gotoAndStop(evtObj.target.name);
mainNav_mc.gotoAndStop(evtObj.target.name);
I need to compare a number with a element in a Array(curModeDisplay), I can trace the element and see it without problem. But when I try to compare the inside element with a String, it didn't work. Why?
ActionScript Code:
curModeDisplay = new Array(); \this is the Array I need
for (var tvM:XMLNode = tv.firstChild; tvM!=null; tvM=tvM.nextSibling){
curModeDisplay.push(tvM.childNodes); \received element fine here
}
trace(curModeDisplay); \ This works fine. Array displays correctly
When I need those elements from the Array(curModeDisplay) and try to make some comparison work, it did not work:
ActionScript Code:
function DigitCompare():Void{
for(var index in curModeDisplay){
if(curModeDisplay[index]=="11265"){ //it seems didn't work here
[code]....
Is that because the element in the Array is reference to the XML node, and "11265" is String. If so, how should I fix this problem. The "11265" will be changed to any named String type variable in the future.
how to make a simple AS3 class.I've made a simple calculator application that allows you to add, subtract, multiply, and divide after entering 2 values into their respective text box.The problem, how ever, is once I moved it into it's own class, I cannot figure out how to reference the text fields. I have the movie clips referenced just fine, but, I cannot figure out the text fields.Here are the errors it's spitting out:
Code:
1120: Access of undefined property Number1_txt.
1120: Access of undefined property Number2_txt.
1120: Access of undefined property finalValue_txt.
And it does that for each instance of those in the Calculator.as
Main.as
Code:
package {
import flash.display.MovieClip;
public class Main extends MovieClip {

I want to be able to reference the text of a text box within an MCThe MC is called "box1", the text field is called "field1"...I have many MCs (all with field1 in them)... box1, box2, box3 etc etcObviously I can set the text to being something by saying...box1.field1.text = "set_this_text"However, I'm using a variable to come up with the "box1" bit. (Using an array and a loop to figure out which box I want to update based on where the user clicked). So, let's say I have a variable... and I want to say..boxClickedon = box1 //will be defined by userSo I don't know in advance about box1... I can only access it through "boxClickedin" variable, but
boxClickedin.field1.text = "set_this_text"
or
[boxClickedin].field1.text = "set_this_text"

Is there a way to reference a function via a variable? In other words, instead of saying something like:
var theVar = someString + 'function';
if (theVar == 'functionName') functionName ();
to access it directly:
(someString + 'function') ();
using some kind of bracket notation?
Using AS2. I have a variable defined:
activenav = "services";
I then want to reference the variable in a MC string. I've tried many variations of this:
_root.my[activenav]Clip.gotoAndPlay("Out");
Essentially, I want Flash to see this as:
_root.myservicesClip.gotoAndPlay("Out");
Getting syntax error.
i have a function that read a variable from a text file, yet i can only read the variable from within the function. How could i create a global variable or such that i can then read from outside of the function.
Code:
var Make:LoadVars = new LoadVars();
Make.onLoad = function() {
VARIABLE = Make.textVariable;
