默认情况下，购物车是隐藏不可见的，当用户点击添加到购物车按钮后，商品信息会添加到购物车，购物车会以按钮的形式出现在页面右下角，点击按钮则会展开购物车，显示购物车中的商品信息，同时也可以对购物车中的商品进行删除或者结算等操作。用户也可以暂时关闭购物车继续购物。
HTML结构
HTML结构主要包括两部分，第一部分是商品列表中的“添加到购物车”按钮，如下代码，我们使用data-*属性将商品的id，图片、名称、价格等信息一并带上。
<a href="#0" class="btn btn-success add-button" data-price="3669.00" data-proid="1" data-proname="华为P9" data-proimg="img/huawei_p9.jpg">添加到购物车</a>第二部分是购物车，购物车部分包括触发购物车以及购物车统计部分 .cd-cart-trigger和购物车主体内容部分.cd-cart。
<div class="cd-cart-container empty">
<a href="#0" class="cd-cart-trigger">
购物车
<ul class="count"> <!-- cart items count -->
<li>0</li>
<li>0</li>
</ul>
</a>
<div class="cd-cart">
<div class="wrapper">
<header>
<h2>购物车</h2>
<span class="undo">已删除 <a href="#0">恢复</a></span>
</header>
<div class="body">
<ul>
<!-- 此部分是购物车商品部分，由javascript动态插入 -->
</ul>
</div>
<footer>
<a href="#0" class="checkout"><em>结算 - ￥<span>0</span></em></a>
</footer>
</div>
</div>
</div>在div.body元素里的ul列表默认是空的，它是用来显示购物车的商品列表信息的，它的大致结构如下，它是由Javascript动态插入的。
<div class="body">
<ul>
<li class="product">
<div class="product-image">
<a href="#0"><img src="img/pro.jpg" alt="placeholder"></a>
</div>
<div class="product-details">
<h3><a href="#0">商品名称</a></h3>
<span class="price">￥3999.99</span>
<div class="actions">
<a href="#0" class="delete-item">删除</a>
<div class="quantity">
<label for="cd-product-'+ productId +'">件数</label>
<span class="select">
<span class="select">x<i id="cd-product-'+proid+'">1</i></span>

}Javascript
本实例代码是基于jQuery，因此需要提前加载jQUery库文件。
当用户点击按钮.add-button后，触发函数addProduct()，将商品信息插入到 .body > ul中。
function addProduct(proname,proid,price,proimg) {
var quantity = $("#cd-product-"+proid).text();
var select='',productAdded='';
if(quantity==''){
var select = '<span class="select">x<i id="cd-product-'+proid+'">1</i></span>';
var productAdded = $('<li class="product"><div class="product-image"><a href="#0"><img src="'+proimg+'" alt="placeholder"></a></div><div class="product-details"><h3><a href="#0">'+proname+'</a></h3><span class="price">￥'+price+'</span><div class="actions"><a href="#0" class="delete-item">删除</a><div class="quantity"><label for="cd-product-'+ proid +'">件数</label>'+select+'</div></div></div></li>');
cartList.prepend(productAdded);
}else{
quantity = parseInt(quantity);
$("#cd-product-"+proid).html(quantity+1);
}
}在购物车中的操作，如删除商品、恢复商品以及更改商品件数会导致结算总金额变动，因此在函数updateCartCount()和updateCartTotal()中会实时触发相关变动。好了，具体的javascript代码如下：
jQuery(document).ready(function($){
var cartWrapper = $('.cd-cart-container');
//product id - you don't need a counter in your real project but you can use your real product id
var productId = 0;
if( cartWrapper.length > 0 ) {
//store jQuery objects
var cartBody = cartWrapper.find('.body')
var cartList = cartBody.find('ul').eq(0);
var cartTotal = cartWrapper.find('.checkout').find('span');
var cartTrigger = cartWrapper.children('.cd-cart-trigger');
var cartCount = cartTrigger.children('.count')
//var addToCartBtn = $('.cd-add-to-cart');
var addToCartBtn = $('.add-button');
var undo = cartWrapper.find('.undo');
var undoTimeoutId;
//add product to cart
addToCartBtn.on('click', function(event){
event.preventDefault();
addToCart($(this));
});
//open/close cart
cartTrigger.on('click', function(event){
event.preventDefault();
toggleCart();
});
//close cart when clicking on the .cd-cart-container::before (bg layer)
cartWrapper.on('click', function(event){
if( $(event.target).is($(this)) ) toggleCart(true);
});
//delete an item from the cart
cartList.on('click', '.delete-item', function(event){
event.preventDefault();
removeProduct($(event.target).parents('.product'));
});
//update item quantity
cartList.on('change', 'select', function(event){
quickUpdateCart();
});
//reinsert item deleted from the cart
undo.on('click', 'a', function(event){
clearInterval(undoTimeoutId);
event.preventDefault();
