JavaScript private methods

Question

To make a JavaScript class with a public method I\'d do something like:

function Restaurant() {}

Restaurant.prototype.buy_food = function(){
   // something         


        

Answer 1

In general I added the private Object _ temporarily to the object. You have to open the privacy exlipcitly in the "Power-constructor" for the method. If you call the method from the prototype, you will be able to overwrite the prototype-method

• Make a public method accessible in the "Power-constructor": (ctx is the object context)

  ctx.test = GD.Fabric.open('test', GD.Test.prototype, ctx, _); // is a private object
  

• Now I have this openPrivacy:

  GD.Fabric.openPrivacy = function(func, clss, ctx, _) {
      return function() {
          ctx._ = _;
          var res = clss[func].apply(ctx, arguments);
          ctx._ = null;
          return res;
      };
  };
