Question

I’m trying to call a function from this:

var _coll = [new Obj('a', somefunction)];

function Obj(id, fn) {
    this.id = id;
    this.fn = fn;
}
var somefunction = (function () {
    return {
        innerFn: function (a) {
            return a
        }
    }
})();
//this works
var test = new Obj('a', somefunction);
alert(test.fn.innerFn('test'));
//this is not working
loopArray();

function loopArray()
for (var it in _coll) {
    for (var its in _coll[it]) {
        var response = _coll[it].fn.innerFn('hey');
        alert(response);
    }
}
}

If I change _coll to “var test=new Obj(‘a’,’somefunction’);”, its ok, but how do I call a function?

Answer 1

Because at the point where you define _coll, the function somefunction is not yet defined.

If you move the call which defines somefunction to top of the code, it will work just fine.
