我正在使用magento网站,有一个部分可以使用ajax将产品加载到购物车中。这工作正常但它只允许一次处理一个请求。当一个人发布到数据库时,您无法选择其他产品,否则它将终止该第一个请求。我的问题是如何(或可能)同时运行多个请求而不取消另一个请求?处理POST的操作是:
public function addAjaxAction()
{
$response = array();
$error = false;
$cart = $this->_getCart();
$params = $this->getRequest()->getParams();
if (isset($params['simple_sku']) && $params['simple_sku'] != '')
$product = Mage::getModel('catalog/product')->load(Mage::getSingleton('catalog/product')->getIdBySku($params['simple_sku']));
else
$product = $this->_initProductInStock();
$related = $this->getRequest()->getParam('related_product');
if (!$product) {
$error = 'Can not add item to shopping cart';
}else{
try {
$cart->addProduct($product, $params);
if (!empty($related)) {
$cart->addProductsByIds(explode(',', $related));
}
$cart->save();
$this->_getSession()->setCartWasUpdated(true);
Mage::dispatchEvent('checkout_cart_add_product_complete', array('product'=>$product, 'request'=>$this->getRequest()));
$response['status'] = 'success';
$response['cart'] = $this->getLayout()->createBlock('checkout/cart_minicart')
->setTemplate('page/html/modals/added_to_bag.phtml')
->setChild(
'breads' ,$this->getLayout()->createBlock('modcheckout/cart_breadcrumbs')->setTemplate('page/html/modals/mini_crumb.phtml')
)
->toHtml();
$response['cartStatus'] = $this->getLayout()->createBlock('core/template')->setTemplate('checkout/cart/status.phtml')->toHtml();
$response['checkoutNow'] = $this->getLayout()->createBlock('core/template')->setTemplate('checkout/cart/checkoutnow.phtml')->toHtml();
}
catch (Exception $e) {
$error = 'Can not add item to shopping cart';
}
}
if($error){
$response['status'] = 'error';
$response['message'] = $error; /*= $this->getLayout()->createBlock('modcore/messages')
->addMessage(new Mage_Core_Model_Message_Error($error))
->getGroupedHtml();*/
}
echo Zend_Json::encode($response);
}
处理响应的js:
function addQuickviewAjax() {
if(productForm.validate()){
if(Product<?php echo $_product->getId() ?>.validate()) {
var params = 'product='+Product<?php echo $_product->getId() ?>.productId+'&qty='+Product<?php echo $_product->getId() ?>.currentQty+'&super_attribute[76]='+Product<?php echo $_product->getId() ?>.currentColor+'&super_attribute[491]='+Product<?php echo $_product->getId() ?>.currentSize;
new Ajax.Request('/modcheckout/cart/addAjax', {
parameters: params,
onFailure: reportError,
onSuccess: function(transport) {
var json = transport.responseText.evalJSON();
if(json.status == 'error'){
alert (json.message);
} else if(json.status == 'success') {
alert ('success');
}
}
});
} else {
return false;
}
}
return false;
}
任何人都可以告诉我所有这些并告诉我如何使用该操作我/如果有多个POST?

浏览器倾向于限制同时请求的数量 - 因此不要发送多个请求,将单个XHR发送到多产品添加操作。为了更好的了解,请查看Mage_Checkout_CartController::addgroupAction()
。
