Cart Class

Each of these methods returns a cart variable to a callback function. You can also supply different Ajax options for even more control.

refresh(callback, options)

Returns the current cart variable.

Cart.refresh(function(cart) {
  alert("I've got " + cart.item_count + " items in the cart!");
});

updateFromForm(formID, callback, options)

Submits a specific form ID to add, update, or remove items from the cart.

Cart.updateFromForm('cart_form', function(cart) {
  alert("Cart updated!");
});

addItem(optionID, quantity, callback, options)

Adds a particular option.id to the cart with the desired quantity (1 by default).

Cart.addItem(1234, 1, function(cart) {
  alert("Item added!");
});

updateItem(itemID, quantity, callback, options)

Updates a particular item.id in the cart with the desired quantity.

Cart.updateItem(1234, 10, function(cart) {
  alert("Item updated!");
});

removeItem(itemID, callback, options)

Removes a particular item.id from the cart.

Cart.removeItem(1234, function(cart) {
  alert("Item removed!");
});
