I´ve defined a class like this:

function Class1(){
    this.Func1 = function(){
       /* Methods and vars */
    };

    function Func2(){
       /* Methods and vars */
    };

};

I want to find out a way to call the public method (or get the value of a public variable) from the private one (Func2()). Any sugestions?

Pd: Sorry if the terminology I used is strongly oriented to objects, because I am a C++ programer, and I'm kinda newby in javascript programming.

• Func2 is actually the "private method" here, and Func1 "public". – Casey Chu Commented Jun 21, 2011 at 5:42

• You should write 'this.Func1 = new function()' instead of 'this.Func1() = new function()' – recamshak Commented Jun 21, 2011 at 5:47
• 1 A little nitpicking here: you should write most functions and methods with camelCase (first letter lowercase) Write your constructor-functions with CamelCase (first letter uppercase). Source: javascript.crockford./code.html – Niels Bom Commented Dec 16, 2011 at 10:00

From Func1, you can call Func2 directly:

this.Func1 = function() {
  Func2();
};

However, you cannot do the same to call Func1 from Func2 because Func2 will (probably) have a different scope and different definition of this when it is called; this.Func1 will be undefined. As alx suggested below, you can save the scope using another variable that will retain its value when used from the inside function. You can also save a reference to Func1 in local scope as follows:

var Func1 = this.Func1 = function() {
  // fun stuff
};

function Func2() {
  Func1();
}

This works because it does not rely on the changing reference this.

use closure:

function Class1(){
        this.Func1 = function(){
           /* Methods and vars */
        };

        var me = this;

        function Func2(){
           me.Func1();
        };

    };

being declared in the same scope, the public method is aware of the private one, thus you can just simply call it :

function Object1(){
    this.publicMethod = function(){         
        alert("I'm a public method ;)");
    };
    var that = this;
    function privateMethod(){
        return that.publicMethod.apply(that,arguments);
    };
};
