Javascript Array inside Array - how can I call the child array name?

Question

Here is the example of what I am doing:

   var size = new Array("S", "M", "L", "XL", "XXL");
   var color =          


        

Answer 1

I would create an object like this:

var options = { 
    size: ["S", "M", "L", "XL", "XXL"],
    color: ["Red", "Blue", "Green", "White", "Black"]
};


alert(Object.keys(options));

To access the keys individualy:

for (var key in options) {
    alert(key);
}

P.S.: when you create a new array object do not use new Array use [] instead.
