在我的Magento网站的类别列表页面中,我在该右侧有一列,当用户点击产品时,该列通过AJAX加载产品的视图页面。我能够从视图页面中检索所有内容,如图像,标签等,但我无法检索产品的可配置选项,因为它们存储为javascript变量。
关于如何检索该信息的任何想法?
编辑 - 更好的解释:我试图让用户直接从类别页面配置产品,向他们显示所有选项,而无需导航到每个产品的视图页面。到目前为止,我只能获得HTML,但下拉列表是空的。这就是因为所有的选择&它们的价格在视图页面中存储为javascript变量。所以我的问题是,我如何通过ajax调用获得这些选项&加载下拉列表&让它们完全按照产品视图页面的方式工作吗?

Magento使用JS,这是事实。它使用Mage_Catalog_Block_Product_View_Type_Configurable
类来呈现可配置的产品。你应该对它的getJsonConfig()
方法感兴趣。正如您所说,它在app/design/frontend/base/default/template/catalog/product/view/type/options/configurable.phtml
模板中用于呈现执行magick的javascript代码。
因此,在模板中看起来像:
<script type="text/javascript">
var spConfig = new Product.Config(<?php echo $this->getJsonConfig() ?>);
</script>
在浏览器中看起来像:
<script type="text/javascript">
var denyProduct = {"62":["12","9"]}
var spConfig = new Product.Config({"attributes":{"70":{"id":"70","code":"manufacturer","label":"Manufacturer","options":[{"id":"11","label":"Fischer","price":"10","oldPrice":"10","products":["61","66"]},{"id":"12","label":"Queen mum","price":"20","oldPrice":"20","products":["62"]}]},"122":{"id":"122","code":"size","label":"Maat","options":[{"id":"9","label":"M","price":"15","oldPrice":"15","products":["61","62"]},{"id":"10","label":"S","price":"0","oldPrice":"0","products":["66"]}]}},"template":"\u20ac\u00a0#{price}","basePrice":"150","oldPrice":"150","productId":"64","chooseText":"Kies een optie...","taxConfig":{"includeTax":true,"showIncludeTax":true,"showBothPrices":false,"defaultTax":19,"currentTax":19,"inclTaxTitle":"Incl. BTW"}});
</script>
创建所有javascript选项的代码是(Mage_Catalog_Block_Product_View_Type_Configurable::getJsonConfig()
方法):
$attributes = array();
$options = array();
$store = $this->getCurrentStore();
$taxHelper = Mage::helper('tax');
$currentProduct = $this->getProduct();
$preconfiguredFlag = $currentProduct->hasPreconfiguredValues();
if ($preconfiguredFlag) {
$preconfiguredValues = $currentProduct->getPreconfiguredValues();
$defaultValues = array();
}
foreach ($this->getAllowProducts() as $product) {
$productId = $product->getId();
foreach ($this->getAllowAttributes() as $attribute) {
$productAttribute = $attribute->getProductAttribute();
$productAttributeId = $productAttribute->getId();
$attributeValue = $product->getData($productAttribute->getAttributeCode());
if (!isset($options[$productAttributeId])) {
$options[$productAttributeId] = array();
}
if (!isset($options[$productAttributeId][$attributeValue])) {
$options[$productAttributeId][$attributeValue] = array();
}
$options[$productAttributeId][$attributeValue][] = $productId;
}
}
$this->_resPrices = array(
$this->_preparePrice($currentProduct->getFinalPrice())
);
foreach ($this->getAllowAttributes() as $attribute) {
$productAttribute = $attribute->getProductAttribute();
$attributeId = $productAttribute->getId();
$info = array(
'id' => $productAttribute->getId(),
'code' => $productAttribute->getAttributeCode(),
'label' => $attribute->getLabel(),
'options' => array()
);
$optionPrices = array();
$prices = $attribute->getPrices();
if (is_array($prices)) {
foreach ($prices as $value) {
if(!$this->_validateAttributeValue($attributeId, $value, $options)) {
continue;
}
$currentProduct->setConfigurablePrice(
$this->_preparePrice($value['pricing_value'], $value['is_percent'])
);
Mage::dispatchEvent(
'catalog_product_type_configurable_price',
array('product' => $currentProduct)
);
$configurablePrice = $currentProduct->getConfigurablePrice();
if (isset($options[$attributeId][$value['value_index']])) {
$productsIndex = $options[$attributeId][$value['value_index']];
} else {
$productsIndex = array();
}
$info['options'][] = array(
'id' => $value['value_index'],
'label' => $value['label'],
'price' => $configurablePrice,
'oldPrice' => $this->_preparePrice($value['pricing_value'], $value['is_percent']),
'products' => $productsIndex,
);
$optionPrices[] = $configurablePrice;
//$this->_registerAdditionalJsPrice($value['pricing_value'], $value['is_percent']);
}
}
/**
* Prepare formated values for options choose
*/
foreach ($optionPrices as $optionPrice) {
foreach ($optionPrices as $additional) {
$this->_preparePrice(abs($additional-$optionPrice));
}
}
if($this->_validateAttributeInfo($info)) {
$attributes[$attributeId] = $info;
}
// Add attribute default value (if set)
if ($preconfiguredFlag) {
$configValue = $preconfiguredValues->getData('super_attribute/' . $attributeId);
if ($configValue) {
$defaultValues[$attributeId] = $configValue;
}
}
}
$taxCalculation = Mage::getSingleton('tax/calculation');
if (!$taxCalculation->getCustomer() && Mage::registry('current_customer')) {
$taxCalculation->setCustomer(Mage::registry('current_customer'));
}
将这些值与<select>
元素相关联的代码位于Product.js
文件中。
如果你只想获得在某个类别中使用的所有属性,这里是解决方案:假设你有一个变量$_productCollection
填充了类别产品。然后你可以执行这个性能突破的代码:
$setIds = array();
foreach ($_productCollection as $k => $product)
{
$setIds[] = $product->getAttributeSetId();
}
/** @var $collection Mage_Catalog_Model_Resource_Product_Attribute_Collection */
$collection = Mage::getResourceModel('catalog/product_attribute_collection');
$collection
->setItemObjectClass('catalog/resource_eav_attribute')
->setAttributeSetFilter($setIds)
->addStoreLabel(Mage::app()->getStore()->getId())
->setOrder('position', 'ASC');
$collection->load();
因此,您将获得$collection
变量中的所有属性(包含重复)。
希望,这会以某种方式帮助你。

这会占用大量的服务器资源,因为每种产品都有很多选项。最好的方法是使用ajax只在需要时加载所有选项。我发现这个扩展会首先加载颜色,然后当你将鼠标移到它上面时会给你所有的产品选项。
