How do you increment a cookie value?

Question

I am wondering how you would go about incrementing cookies (by one, just to keep in basic.)

var snacks = $cookies.get('fruitSnacks', 1);
snacks ++;`

Answer 1

try this

var snacks = $cookies.get('fruitSnacks') + 1 ;


$cookies.put('fruitSnacks', snacks );

Answer 2

The Angular Way

The Angular solution would be:

var oldVaue = $cookies.get('my-cookie');
$cookies.put('my-cookie', ++oldValue);

The jQuery Solution

With the jquery-cookie plugin you can handle cookies more easily:

var oldValue = $.cookie('my-cookie');
$.cookie('my-cookie', ++oldValue);

---

Now the library was superseded by js-cookie, here is the solution with that:

var oldValue = Cookies.get('my-cookie');
Cookies.set('my-cookie', ++oldValue);
