Flex 3: Getting variables from URL

Question

If I have an application located at http://sitename.com/myapp/ and i want to pass in a variable via the url (i.e. - http://sitename.com/myapp/?name=Joe), how can I get that

Answer 1

Divide 'em with String.split() and conquer:

    var url:String = "http://www.xxx.zzz/myapp?arg1=vae&arg2=victus";
    var params:String = url.substr(url.lastIndexOf("?") + 1);
    if (params.length == url.length) return; //no params
    for each (var pair:String in params.split("&"))
    {
        trace("Got parameter:");
        var nameValue:Array = pair.split("=");
        trace("name: " + nameValue[0] + ", value: " + nameValue[1]);
    }

Output:

Got parameter:
name: arg1, value: vae
Got parameter:
name: arg2, value: victus
