How to get/obtain Variables from URL in Flash AS3

Question

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

example link:
http://www.example.com/example_xml.php?aID=1234&bID=5678

I need to get the aID and the bID numbers.

I'm able to get the full URL into a String via ExternalInterface

var url:String = ExternalInterface.call("window.location.href.toString");
if (url) testField.text = url;

Just unsure as how to manipulate the String to just get the 1234 and 5678 numbers.

Appreciate any tips, links or help with this!

Answer 1

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
