Store a Function

[dai.hop]

Hi all,

I was wondering if there is a way to store a function? For example, if I called a function like so:

test('dave', 1, 2);

...is there a way to store this function along with its variables in something like:

var last_test = function test('dave', 1, 2);

...then calling it again later using something like:

last_test.execute();

Thanks!

Functions are first-class objects, just like any other object, so can be assigned to an object - this is normally referred to as making them a 'method of an object', so there is no need for the ".execute" bit: you just do: last_test();

So if I make my function the method of an object what will happen with the variables from the last call? Will they not need to be passed anymore?

i.e.

test('dave', 1, 2);

...would become...

object.test();

?

That depends on how you _want_ to handle them - for more info have a look at reference material firstly for: "function literal format" and then for "closures"

You can either pass the function parameters when you define the function, or when you call it.
You may want to consider a half-way house, where you do:
object.methodName = myFunction;
object.parameters = myParamList;

That way you get use the function repeatedly, but change the parameters when you need.

var last_test = function(){return  test('dave', 1, 2); }

calling it again later:

last_test();
