Is there a way to get the current function from within the current function?

Question

Sorry for the really weird title, but here’s what I’m trying to do:

var f1 = function (param1, param2) {

    // Is there a way to get an object that is ‘f1’         


        

Answer 1

You can access it with f1 since the function will have been assigned to the variable f1 before it is called:

var f1 = function () {
    f1(); // Is valid
};

f1(); // The function is called at a later stage

Answer 2

Yes – arguments.callee is the current function.

NOTE: This is deprecated in ECMAScript 5, and may cause a performance hit for tail-call recursion and the like. However, it does work in most major browsers.

In your case, f1 will also work.

Answer 3

Name it.

var f1 = function fOne() {
    console.log(fOne); //fOne is reference to this function
}
console.log(fOne); //undefined - this is good, fOne does not pollute global context
