如何打电话给私人＆amp;命名空间内的公共函数

Question

我有一个名称空间，它具有很少的私有和公共功能。如何从另一个公共函数（在同一命名空间内）调用它们？

var myns = (function () {    
  var module = {};   

  function private_F1() {        
  }

  function private_F2() {

  }    

  // public
  module.public_doSomething = function () {        
  };

  module.Init= function () {
    // Why cant i call functions inside the same namespace using "this"

    this.private_F1(); //does not work with "this" keyword

    private_F1(); //worked  without "this" keyword

    this.public_doSomething() //does not work with "this" keyword

    public_doSomething //does not work without "this" keyword

    myns.public_doSomething() //worked with namespace
  };

  return module;

})();
