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?

var sample = new Array();
sample[0] = 'one';
sample[1] = 'two';

var arrayname = "sample";
var number = arrayname[1];  ///  Something like this, although I realize this doesn't work for obvious reasons...

I’ve read other questions in regards to using an variable value as a function, but I didn’t understand the approach or even if this would work for the above situation.

Thanks in advance!!

This should do it:

    var sample = new Array();
    sample[0] = 'one';
    sample[1] = 'two';

    var arrayname = "sample";
    var number = window[arrayname][1];
    alert(number);
