How to point to an JS Array by Name in the Form of String?

Question

I have a JS array.

//This is Dynamic, I maynot know the name in the beginning
var myArray = ["apple","ball","cat"];

var NameOfArray = "myArray";

How can I access myArray if I know only it's name in the form on String? In PHP, I would use $$. How Do I do that in JS?

I think this is the answer :) http://stackoverflow.com/questions/5117127/use-dynamic-variable-names-in-javascript — Ali insan Soyaslan, Dec 26 '14 at 22:14

Depending on where the array is defined, you can access it directly i.e. if it is defined globally as in your example:

console.log(window[NameOfArray][1]); // Outputs "ball"

Use:

eval("myArray")

It is an array which has the contents of myArray.

If you're able to control the name of the variable NameOfArray, i.e. control the code, you could just set it as a variable on the window in that line using eval

var myArray = [1,2,3];
window.theArrayIWant = eval('myArray');

then using theArrayIWant moving forward
