You don't need jQuery. You could do it like:

 var item = list.split(',')[3]; //Gets 4th item

Edit

As other people have pointed out below, it might be better to have the list in an array in the first place.

var list = [1,2,3,4,5,6];
//Rather than
var list = '1,2,3,4,5,6';

Although having it as a string then splitting does have some benefits:

var list = '1,2,3,4,5,6'.split(",");

I don't know why you want to use jQuery for this.You can do something like that;

var myArray=["1","2","3"];

and get value with myArray[i]

The proper way of define a list in javascript should be 

var i = [1,2,3,4,5,6]

after that, you can just retrieve the value using i[3], which is 4. You don't really need to use jQuery as javascript support it by default

jQuery... why not native javascript functions?

If your list is a string with a comma deliminator...

var list = "1,2,3,four,five,six";
var third = list.split(",")[2];

Otherwise..

var list = [1,2,3,4,5,6];
var third = list[2];

jQuery is moreso used for programability of DOM elements and data objects.
