要调用Ajax，必须首先调用checkout cart块
$cartHtml = $this->getLayout()->createBlock('checkout/cart')->setTemplate('checkout/cart.phtml')->toHtml();
之后，您必须将响应发送到编写Ajax代码的cart.phtml文件
$response['cart_html'] = $cartHtml;
$this->getResponse()->setBody(Mage::helper('core')->jsonEncode($response));
您在上述代码中是否遇到任何错误？
