How to encode cookie with javascript/jquery?

Question

I am working on an online shop together with my friend. He set a cookie for me with PHP with the amount of added products to the Cart. The cookie is called \"cart\", and the

Answer 1

That is the URL encoded equivalent of {"items":{"8":1}} which is the JSON string you want.

All you have to do is decode it and parse the JSON:

var cart = JSON.parse(decodeURIComponent(document.cookie.cart));

Then logging cart should give you an object with an 'items' property that you can access as needed.

EDIT:

As an example, here's a way to iterate through the items and determine the total number of items and the total of all their quantities.

var items_total = 0,
    quantity_total = 0;
for (var prop in cart.items) {
    items_total += 1;
    quantity_total += cart.items[prop];
}

console.log("Total Items: " + items_total);
console.log("Total Quantities: " + quantity_total);

Looks like you just need to decode it, then you will want to parse/eval it to get a workable object:

var obj, decoded = decodeURIComponent(document.cookie.cart);
if(window.JSON && JSON.parse){
  obj = JSON.parse(decoded);
} else {
  eval('obj = ' + decoded);
}
// obj == {"items":{"8":1}};
