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 = new Array("Red", "Blue", "Green", "White", "Black");    var options = new Array( size, color); 

I am doing a loop select form thingies which work good, but I want to fetch the Array child name, in this case - size or color. When I am doing alert(options[0]), I get the whole elements of array. But for some specific case, I want to get only the array name, which is size/color like I have said already. Is there way to achieve that?

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.
