RE: [Flashcoders] Accessing an Associative Array
Right -
myArray["hello"] = "hi"
is the same as:
myArray.hello = "hi"
Depends on your coding preferences. Personally, I prefer Alain's
suggestion of object dot-notation syntax:
myArray.hello
if the array's name is variable, then:
this[myArray].hello

RE: [Flashcoders] Accessing an Associative Array
Actually you have an Object not an Array when you define your variable :
var myarray = { text:"Lorem ipsum" };
is the same as
var myarray:Object = new Object();
myarray.text = "Lorem ipsum";
but with Actionscript you can access objects with the array notaion []
var i:Number = 1;
var myMC:String = "movieClip"+i;
this[myMC]._x = 26;
myarray["text"] = "Lorem Ipsum";
instead of
this.movieClip1._x = 26;
myarray.text = "Lorem Ipsum";
If you really want an associative array, look at Jason's answer
Otherwise keep on using the Object notation, but you will lack all the Array
object specific methods

Re: [Flashcoders] Accessing an Associative Array
Cool. That's it. Thanks so much!
Needed to use the syntax;
this[myStringVariableAndArrayName]["myLabelInMyAssociativeArray"];
My final code:
// Show the popup
function showPopup(popup) {
trace(popup);
mainMap[popup].gotoAndPlay("on");
mainMap[popup].label_title.text = this[popup]["labelText"];
trace(this[popup]["labelText"]);
};

Easy, just keep using the array access operator to evaluate:
myVar = "myArray2"
myArray1 = new Array()
myArray1["elem1"] = "hello"
myArray1["elem2"] = "hi"
myArray2 = new Array()
myArray2["elem1"] = "wassup"
myArray2["elem2"] = "yo"

Re: [Flashcoders] Accessing an Associative Array
Your right. I am passing a string.
But I'm trying to use that string to access an array by the same name.
someArray = { label: "my text" };
showPopup("someArray"); // send a string which is the name of my array
in the function:
myDynamicText.text = myArray["label"]; // try to use the passed
string to access the array.
This won't access some array. How do I convert that string over to
something that will work?

Re: [Flashcoders] Accessing an Associative Array
Variable identifiers are not string constants, so:
showPopup(myarray);
However mainMap[popup].gotoAndPlay("on"); has no sense in this case,
since the array notation excepts a string and not an object. Ans also
you don't need to use array notation here at all, the simple dot
syntax is enough: myarray.text and popup.text
