If you send variables to your Flash movie using flashVars the following function could be used to gather all of the variables up into an object. Number values are converted to true numbers, and you can also name your flashVars so they are recreated as arrays.

Here's the function:

function getFlashVars():Object {
    var o:Object = {};
    var n:String;
    var i:Number;
    var s:String;
    for (s in _level0) {
        if (s.substr(0,3) == "fv_") {
            n = s.substr(3);
            if (n.indexOf("_") > -1) {
                i = Number(n.split("_")[1]);
                n = n.split("_")[0];
                if (o[n] == null) {
                    o[n] = [];
                }
                if (isNaN(_level0[s])) {
                    o[n][i] = unescape(_level0[s]);
                }
                else {
                    o[n][i] = Number(_level0[s]);
                }
            }
            else {
                if (isNaN(_level0[s])) {
                    o[n] = unescape(_level0[s]);
                }
                else {
                    o[n] = Number(_level0[s]);
                }
            }
        }
    }
    return o;
} 

Here are a few examples of use. Note that each flashVar name is prefixed with fv_

01 - Basic example

HTML

<param name="flashVars" value="fv_foo=hello&fv_bob=123" />

AS

var info:Object = getFlashVars();
 
trace( info.foo ); // output: hello
trace( info.bob ); // output: 123
trace( typeof info.bob ); // output: number 
 

02 - Sending Arrays

To send an array to Flash you simply add _0 _1 _2 etc to the end of your variable name.

HTML

<param name="flashVars" value="fv_items_0=apple&fv_items_1=banana" />

AS

var info:Object = getFlashVars();
 
trace( info.items[0] ); // output: apple
trace( info.items[1] ); // output: banana
