Limit quantity of items that can be added to cart - simpleCart

Question

Trying to limit the total quantity of items allowed to be added to 4, this function alerts first time but still adds items to the cart.

simpleCart.bind( 'beforeAdd' , function( item ){

        if(simpleCart.quantity() === 4 ){

             alert("You can only compare 4 items."); 
             return false;

        }

   });

It only checks for the 4th element added and keeps adding elements. If you make it to check if the quantity is equal or bigger than 4 to prevent adding more items :)

simpleCart.bind( 'beforeAdd' , function( item ){

    if(simpleCart.quantity() >= 4 ){

         alert("You can only compare 4 items."); 
         return false;

    }

});

Hmm still adds the item though. – user1199795 Oct 22 '14 at 13:26
Do you have some errors in the console? Maybe something else is not working properly. – Bojan Petkovski Oct 22 '14 at 13:39
no errors, I'm adding items with inline JS, does that matter? – user1199795 Oct 22 '14 at 16:34

SimpleCart (v3) passes an item to beforeAdd that represents only the item and quantity that is being added to the cart. The code needs to take into account any items already in the cart.

simpleCart.bind('beforeAdd', function (item) {
    var requestedQuantity = item.get('quantity');
    var existingItem = simpleCart.has(item);
    if (existingItem) {
        requestedQuantity += existingItem.get('quantity');
    }
    if (requestedQuantity > 4) {
        alert("You may compare at most 4 items.");
        return false;
    }
});
