So I have a URL that I need my Flash movie to extract variables from:

I need t

Answer 1

var valuePairs:Array = url.substring(url.indexOf("?")+1).split("&");
var map:Object = new Object();
for (var i:int=0; i < valuePairs.length; i++) {
    var nextValuePair:Array = valuePairs[i].split("=");
    map[nextValuePair[0]] = nextValuePair[1];
}


trace(map["aID"]); // 1234

Untested code! This is just with simple string manipulation.

and... almost 1-liner (also untested)

var map:Object = new Object();
var temp:Array;
for each (var i:String in /.*\?(.*)/.exec(url)[1].split("&")) map[(temp=i.split("="))[0]]=temp[1];

but of course it's probably better to go with urlVariables :)

Answer 2

Create a new instance of URLVariables.

// given search: aID=1234&bID=5678
var search:String = ExternalInterface.call("window.location.search");
var vars:URLVariables = new URLVariables(search);
trace(vars.aID); // 1234
trace(vars.bID); // 5678
