Question

I have two functions here

function Preloader() {}
Preloader.prototype = {
    init:function() {
        // do something
    }
}

var preloader = new Preloader();

function Project() {}
Project.prototype = {
    init:function() {
        // do something else 
    }
}

var project = new Project();

I want to call project.init() in preloader’s init function but obviously

project.init()

doesn’t work ’cause there’s no project variable in preloader. How should I call it? Thanks!

Answer 1

Preloader.prototype = {
    init:function(project) {
        project.init();
    }
}

var preloader = new Preloader(),
    project = new Project();

preloader.init(project);
