Question

Quick and strange question:

I have an object (in this example is small but in the project is larger):

var myObject = {
   hello: 1, // easier I think
   'hey.ya': 5 // quite impossible but the first option is valid too
}

then I want to pass somehow to a function and use “hello” for example in a closure like this

function x(){
// my closure
   return function(){this.init = function(){alert(hello)}, this.heyYa = function(){alert(/* I do not know how to call the other hey.ya variable */)}}
}

var myClass = x(), instance = new myClass(); instance.init();

thanks!

You need to use the myObject

var myObject = {
   hello: 1,
   'hey.ya': 5
}

function x(obj){
   return function(){
       this.init = function(){
           alert(obj.hello)
       }, 
       this.heyYa = function(){
           alert(obj['hey.ya'])
       }
   }
}

var myClass = x(myObject);
var instance = new myClass(); 
instance.init(); // alerts '1'
instance.heyYa(); // alerts '5'
