Overview

The jsma cart provides access to the current session cart object. Whenever a user creates a session, a cart object will be created lazily (it will be created when first time accessing JSMA carts method carts.current).

What can JSMA cart do for me?

You can use the JSMA cart to manage a users shopping session and facilitate the transaction.

Usage

writing data

Here is an example on how to write data to a JSMA cart:

function updateShipping(countryCode)
{
  //calculate current shipping cost
  var cart = carts.current;
    
  //retrieve country code
  var country = countryCode;
  if (!country) {
    country = cart.shippingAddress.countryCode;
  }
    
  if (!country) {
    cart.setShipping(0);
    return;
  }

  [...]
}

reading data

    price : 0,
    shipping : 0,
    tax : 0,
    items : [],
    voucher : null
  };
    
  var cart = carts.current;
    
  //core values for cart
  result.id = cart.uuid;
  result.amount = cart.price;
  result.shipping = cart.shipping;
  result.tax = cart.tax;
  result.attributes = {};
    
  //add cart attributes
  cart.flexAttributes.forEach ( function ( key ) {
    result.attributes[key] = cart.get(key);
  });
