How to parse Multiple Values in one Cookie in Javascript

I have a cookie that stores 5 values separated by commas in one cookie. I'm able to retrieve the value of ExampleCookie as follows (as example):

var CookieValue = readCookie('ExampleCookie'); //returns Foo,Bar,Foo1,FooFighter,Bar2

How do I parse through CookieValue to assign individual variables such that I can assign a variable to each of the 5 parts?

I've found ways to do this with PHP but not javascript.

Thanks in advance for any advice.

I quickly realized this was more of a question on Split than about cookies. Here is what i came up w/.

var splits = ExampleCookie.split(","); 
var slot1 = splits[0]; 
var slot2 = splits[1]; 
var slot3 = splits[2]; etc.

JSON.stringify, and JSON.parse are your best cleanest bets (imho)

var values = JSON.parse(readCookie('ExampleCookie'));

createCookie('ExampleCookie',JSON.stringify(values));

This has the added benefit of being able to set key values in your object/array.

Assuming you're using the functions found at quirks mode just ensure your cookie values stringified don't go over the 4000 char limit found in most browsers.

You could split the CookieValue into individual values in an array via the the split() method.

var valList = CookieValue.split(','); // ["Foo", "Bar", "Foo1", "FooFighter", "Bar2"]

If you then want the values to be assigned to individual variables, you would need to loop through the array and manually make the assignment.

You need to make an array from string:

CookieParams = CookieValue.split(",");
CookieParams[0] = Foo
CookieParams[1] = Bar

use the String.split(delimiter) method

var array = readCookie('ExCook').split(",");
