How to list all of javascript functions beginning with _func

Question

Is it possible to list / return in an array all javascript functions in my own .js file that begin with the string "_func"?

Done in WebKit's JSCore.

Basically, if my file has a bunch of functions, how do I enumerate those functions?

Are those functions global functions? They better not be. :) — Šime Vidas

They can either be global or nested inside other functions... or they can be properties of objects. — Šime Vidas

You can loop through the members of the window object and test them:

var functions = [];

for( var x in window) {
    if(typeof window[x] === "function" && x.indexOf("_func") === 0) {
        functions.push(x);
    }
}

This won't work in a Webkit environment outside of a browser, because 'window' is defined.

@David In global code the this keyword references the global object, so you can replace window with this...

You can do it by iterating over the members of the window object:

for (var name in window) {
    if (name.match(/^_func/) && typeof window[name] == 'function') {
        console.log(name);
    }
}
