Retrieving elements from array javascript

Question

I have two arrays in js

var array1=new Array("KS","NB","SD","ND","MN");
var array2=new Array("TX","LA","OK","AR");

Some how I will get the name of the array that should be retrieved. Now what I want is, if I get

var arrayTobeSelected = 'array1';

If I console.log arrayTobeSelected, what I get is the string 'array1'. How can I get the elements in the array array1 ?

If arrays are in the global scope, you can do:

console.log(window[arrayToBeSelected]);// you can do [0] or [1] to get specific elements

You're getting a string because:

var arrayTobeSelected = 'array1';

and not:

var arrayTobeSelected = array1;

if you have to get it as string, then just do this:

console.log(eval(arrayTobeSelected));

You can use this code for print all the element of array.

 for(var i = 0; i < array.length; i++){
             console.log(i + " = " + array[i]);
   }
       console.log(array);
       console.log("end");
