How to use dynamic variable in javascript

Question

I have a dynamically created variable called item_908 (where 908 is dynamically). Later on, there is a variable called id, which holds the string "908".

Now, i need to access the variable item_908 programmatically and i cannot remember how to do it. Can anyone tell me how?

Just don't do dynamic variables. Use a friggin' array. Or if it's more than a number, an object. But don't pollute scopes. — user395760

If they are in the global scope:

window["item_" + id];

else you can only access them throu an Object:

var obj = {},
    id = 908;

obj.item_908 = "abc";


obj["item_" + id]; // abc

You may access it by using:

window['item_908'];
