Question

My problem is pretty easy to understand. I have a JSON object (see code) and I will automatically call all functions of this object in the order that those appears.
.

var installer = {
    a : function() {
          ...
        }
    b : function() {
          ...
        }
};

for(var func in installer) {
    fn.call(document);
};

Have you any idea why the previous code doesn’t work ? I’m sorry, I’m a beginner in javascript.

Thanks in advance !

Regards.

Answer 1

You declare var func as the variable to loop through the members of installer, yet you use fn.call(...). Where did fn come from?

Should you be able to do: installer[func].call(document) instead of fn.call(document).

Also your functions declared in the installer object don’t take any arguments, yet you’re passing document as an argument.

[updated code to add missing .call to installer[func](document)]
