Question

The code below shows how to pass a callback function in Flex.

I need to pass a javascript callback function named ‘jsf’ to f1.

How would I create a reference to the callback function ‘jsf’ which is in a .js file?

ie. f1(jsf);

function f():void { trace("I am callback"); }
var v:Vector.<Function> = new <Function>[];
function f1(callBack:Function):void
{
    trace("I register callBack");
    v.push(callBack);
}
function f2():void
{
    trace("I call the callBack");
    v[0]();
}
f1(f);
f2();

Thanks
