Using a variable value to call an array element

Question

I have a string variable which contains the name of an array. What I\'d like to do is access an element of that array. And write it to another variable. How can I do this?

Answer 1

If it's in the global scope, you can access your array by doing

var sample = new Array();
sample[0] = 'one';
sample[1] = 'two';
var arrayname = "sample";
var number = (window[arrayname])[1]
