- CART

This example is built upon the DOM Method example in this `node` module. It just has more CSS and some images.

## Setting up the HTML

First we need some HTML for a store.

    <ul id="demo">
        <li>
            <a>
                <img src="../assets/node/images/store_soup_tomato.png">
                <span class="description">Campbells Tomato Condensed Soup - 10.75 Oz</span>
                <span class="price">
                    <sup>$</sup><span class="dollars">1</span><sup class="cents">.49</sup>
                </span>
            </a>
        </li>
        <!-- For each item in the store there's an li like the above -->
    </ul>

Then we need some HTML for a shopping cart.

    <ul id="demo2">
        <li class="cart-head">
            <img src="../assets/node/images/store_cart.png" width="35" height="38"> <span>CART</span>
        </li>
    </ul>

## Using DOM Methods

Most common DOM methods are available via Node instances. These can be used to add, remove, and retrieve other nodes.

    clone = item.cloneNode(true);
    list2.append(clone);
    item.remove(); // sugar for item.get('parentNode').removeChild(item);

## The JavaScript

The script for this example is very similar to the DOM Method example

    <script type="text/javascript">
    YUI().use('node', 'event-touch', function(Y) {
        var onClick = function(e) {
            e.preventDefault();
            var item = e.currentTarget,
                list2 = Y.one('#demo2');

            if (item.get('parentNode') === list2) { // remove if click is in the cart
                // remove from cart only if it's not the cart header
                if (item.hasClass('cart-head') === false) {
                    item.remove(); // sugar for item.get('parentNode').removeChild(item);
                }
            } else { // else add a clone of the clicked item to the cart
                list2.append(item.cloneNode(true));
            }
        };

        Y.one('#demo').delegate('click', onClick, 'li');
        Y.one('#demo').delegate('touchstart', onClick, 'li');
        Y.one('#demo2').delegate('click', onClick, 'li');
        Y.one('#demo2').delegate('touchstart', onClick, 'li');
    });
    </script>

## The CSS

Just like the DOM Method example in this `node` module, when an item on the left (store) is clicked, an identical clone of that item is added to the list on the right (cart). The only thing that makes the cart items look different from the store items is the CSS.
