Access prototype function within a prototype function

Question

I'm trying to call login function defined in prototype but the function make the call (refresh) is also in the prototype.

function Checker() {
        var self = this;
        self.refresh();
        window.setInterval(function(){self.refresh()}, 1000);

}
Checker.prototype = {

        refresh: function() {
             if(some condition){
                 login(); // this won't work, neither self.login();
             }
        },
        login: function() {

        }
};

How do I call login function within refresh function?

Answer 1

From a prototype method, the instance is set to this. So this.login() is what you want.

Answer 2

That's simple: Use this.login()
