我想使用带模块的ajax更新购物车项目。我覆盖控制器，产品从视图页面添加到购物车工作正常。匿名告诉我如何在不重新加载页面的情况下更新购物车项目。
我的config.xml是
<config>
<modules>
<Module_Ajax>
<version>0.1.0</version>
</Module_Ajax>
</modules>
<frontend>
<routers>
<ajax>
<use>standard</use>
<args>
<module>Module_Ajax</module>
<frontName>ajax</frontName>
</args>
</ajax>
</routers>
<layout>
<updates>
<ajax>
<file>ajax.xml</file>
</ajax>
</updates>
</layout>
</frontend>
<global>
<resources>
<ajax_setup>
<setup>
<module>Module_Ajax</module>
</setup>
<connection>
<use>core_setup</use>
</connection>
</ajax_setup>
<ajax_write>
<connection>
<use>core_write</use>
</connection>
</ajax_write>
<ajax_read>
<connection>
<use>core_read</use>

</ajax_read>
</resources>
</global>
<global>
<rewrite>
<ajax_cart> <!--This can be any unique id -->
<from><![CDATA[#^/checkout/cart/#]]></from>
<to>/ajax/index/</to>
</ajax_cart>
</rewrite>
</global>
</config>
这是我覆盖的CartController，我想更新购物车项目 我的控制器文件是

要调用Ajax，您必须先调用结帐购物车块
$cartHtml = $this->getLayout()->createBlock('checkout/cart')->setTemplate('checkout/cart.phtml')->toHtml();
之后，您必须向您的cart.phtml文件发送响应，其中包含您的Ajax代码。
$response['cart_html'] = $cartHtml;
$this->getResponse()->setBody(Mage::helper('core')->jsonEncode($response));
