Test for functions names in javascript script (SpiderMonkey engine)

Question

I am embeding SpiderMonkey (mozila javascript) interpreter/engine in my C/C++ application. i programatically loading a javascript script and want to test (from my C/C++ code) if a certain function exist/defined in this script.

is there a way to do that ? maybe a way to list all functions in a given script ?

Tnx, Vertilka

As far as I know, this, by default, refers to the global scope. So you can:

(function() {
    var globals = this;
    for (var i in globals) {
        if (typeof globals[i] == 'function') {
            // a function named i is defined.
        }
    }
})();
