How to list the functions/methods of a javascript object? (Is it even possible?)

Question

This question is intentionally phrased like this question.

I don't even know if this is possible, I remember vaguely hearing something about some properties not enumerable in JS.

Anyway, to cut a long story short: I'm developing something on a js framework for which I have no documentation and no easy access to the code, and it would greatly help to know what I can do with my objects.

Answer 1

If you include Underscore.js in your project, you can use _.functions(yourObject).

Answer 2

I think this is what you are looking for:

var obj = { locaMethod: function() { alert("hello"); }, a: "b", c: 2 };
for(var p in obj)
{
    if(typeof obj[p] === "function") {
      // its a function if you get here
    }
}
