Question

I have an object in javascript:

admins: {
    articles: {
        path: '/admins/articles',
        template: '/views/admins/articles.html',
        link: function() {
            return path;  // !!! how to reference the 'path'?
        }
    }
}

I have a lot of objects like this, and each of them has a path field and a link function. I want to use the field path in link, but I can’t just use path.

What should I do?

You can use this to reference the object. Standard object.method() “dot” syntax will set this to object within method:

var someObj = {
    admins: {
        articles: {
            path: '/admins/articles',
            template: '/views/admins/articles.html',
            link: function() {
                return this.path; // !!! how to reference the 'path'?
            }
        }
    }
};

var returnedPath = someObj.admins.articles.link();

(There are other ways to call a function such that this will not be set to the appropriate object, but I hope they don’t apply here – you don’t really say how you’re using the objects or calling the function, but if not in the way I showed then please update your question and I’ll update my answer accordingly.)
