Question

If I have a function like:

        public function defaultValues(first = 1,second =2,third = 3)
        {
            trace(first);
            trace(second);
            trace(third);
        }

How can I call this function by only passing in a value for second = 20 ?

ActionScript3 does not support named parameters. If you really want this behavior, you can use an associative array… but I don’t recommend it unless you really want to be dynamic :

public function defaultValues(params:Object)
{
    var first = "first" in params ? params.first : 1;
    var second = "second" in params ? params.second : 2;
    var third = params.third ? params.third : 3;

    trace(first);
    trace(second);
    trace(third);
}

Then, you can call it:

defaultValues({second: 99});
