在Magento产品页面的使用jqZoom

Magento在产品页面提供了一个简单的图片放大功能，不是非常好，假设考虑使用放大镜来使用户查看产品的大图。能够考虑使用基于jQuery的插件，jqZoom便是一款优秀的放大镜插件。以下将介绍如何把jqzoom集成到Magento中。

1 载入jQuery

由于jqZoom是基于jQuery的插件，所以我们须要在Magento中载入jQuery库，并下载jqZoom文件包，放在站点的根文件夹的js文件夹下，比方/js/jqzoom

2 建立模块

作为样例，我们在/app/code/local/MagentoBoy/Jqzoom文件夹下新建一个模块MagentoBoy_Jqzoom。并加入模块文件：

/app/etc/modules/MagentoBoy_Jqzoom.xml

<?xml version="1.0"?>
<config>
    <modules>
        <MagentoBoy_Jqzoom>
            <active>true</active>
            <codePool>local</codePool>
        </MagentoBoy_Jqzoom>
    </modules>
</config>

并加入配置文件

/app/code/local/MagentoBoy/Jqzoom/etc/config.xml

<?xml version="1.0"?>
<config>
    <modules>
        <MagentoBoy_Jqzoom>
            <version>0.1.0</version>
        </MagentoBoy_Jqzoom>
    </modules>
</config>

3 加入Layout文件

/app/design/frontend/default/default/layout/jqzoom.xml

<?xml version="1.0"?>
<layout>
    <catalog_product_view>
        <reference name="head">
            <action method="addItem"><type>js</type><name>jqzoom/js/jquery.jqzoom-core.js</name></action>
            <action method="addItem"><type>js_css</type><name>jqzoom/css/jquery.jqzoom.css</name></action>
        </reference>
        <reference name="product.info.media">
            <action method="setTemplate"><template>jqzoom/media.phtml</template></action>
        </reference>
    </catalog_product_view>
    <review_product_list>
        <reference name="head">
            <action method="addItem"><type>js</type><name>jqzoom/js/jquery.jqzoom-core.js</name></action>
            <action method="addItem"><type>js_css</type><name>jqzoom/css/jquery.jqzoom.css</name></action>
        </reference>
        <reference name="product.info.media">
            <action method="setTemplate"><template>jqzoom/media.phtml</template></action>
            <action method="disableGallery"/>
        </reference>
    </review_product_list>
</layout>

并在config.xml中加入layout文件

<config>
    <frontend>
        <layout>
            <updates>
                <jqzoom>
                    <file>jqzoom.xml</file>
                </jqzoom>
            </updates>
        </layout>
    </frontend>
</config>

4 改动template文件

/app/design/frontend/default/default/template/jqzoom/media.phtml

<?php
    $_product = $this->getProduct();
    $_helper = $this->helper('catalog/output');
?>
<?php if ($_product->getImage() != 'no_selection' && $_product->getImage()): ?>

<p class="product-image">
    <a href="<?php
 echo $this->helper('catalog/image')->init($_product, 'image');?>" class="jqzoom" rel="gal1" title="<?php
 echo $this->htmlEscape($this->getImageLabel());?>">
        <img id="image" src="<?php
 echo Mage::helper('catalog/image')->init($_product, 'thumbnail')->resize(265);?>" alt="<?php
 echo $this->htmlEscape($this->getImageLabel());?>" title="<?php echo
 $this->htmlEscape($this->getImageLabel());?>" style="265px;" />
    </a>
</p>

<p class="zoom-notice" id="track_hint"><?php echo $this->__('Hover
 on image to zoom in the picture') ?></p>

<?php else: ?>
<p class="product-image">
    <?php
        $_img = '<img
 src="'.$this->helper('catalog/image')->init($_product, 'image')->resize(265).'"
 alt="'.$this->htmlEscape($this->getImageLabel()).'"
 title="'.$this->htmlEscape($this->getImageLabel()).'"
 />';
        echo $_helper->productAttribute($_product, $_img, 'image');
    ?>
</p>
<?php endif; ?>

<?php if (count($this->getGalleryImages()) > 0): ?>
<div class="more-views">
    <h2><?php echo $this->__('More
 Views') ?></h2>
    <ul>
        <li>
            <a class="zoomThumbActive" href="javascript:void(0);" rel="{gallery:'gal1',
 smallimage:'<?php echo Mage::helper('catalog/image')->init($_product, 'thumbnail')->resize(265);?>', largeimage:'<?php echo $this->helper('catalog/image')->init($_product, 'image');?>'}" title="<?php
 echo $this->htmlEscape($this->getImageLabel());?>"><img src="<?php
 echo Mage::helper('catalog/image')->init($_product, 'thumbnail')->resize(56);?>" width="56" height="56" alt="<?php
 echo $this->htmlEscape($this->getImageLabel());?>" /></a>
        </li>
    <?php foreach ($this->getGalleryImages() as $_image): ?>
        <li>
            <a href="javascript:void(0);" rel="{gallery:'gal1',
 smallimage:'<?php echo Mage::helper('catalog/image')->init($_product, 'thumbnail', $_image->getFile())->resize(265);?>', largeimage:'<?php echo $this->helper('catalog/image')->init($_product, 'image', $_image->getFile());?>'}" title="<?php
 echo $this->htmlEscape($this->getImageLabel());?>"><img src="<?php
 echo Mage::helper('catalog/image')->init($_product, 'thumbnail', $_image->getFile())->resize(56);?>" width="56" height="56" alt="<?php
 echo $this->htmlEscape($this->getImageLabel());?>" /></a>
        </li>
    <?php endforeach; ?>
    </ul>
</div>
<?php endif; ?>
<script type="text/javascript">
//<![CDATA[
var $j = jQuery.noConflict();
$j(document).ready(function(){
    $j('.jqzoom').jqzoom({
        'zoomWidth' : 300,
        'zoomHeight' : 300,
        'xOffset' : 10,
        'yOffset' : 0,
        'position' : 'right',
        'preloadImages' : true,
        'preloadText' : 'Loading zoom',
        'title' : true,
        'lens' : true,
        'imageOpacity' : '0.4',
        'showEffect' : 'show',
        'hideEffect' : 'hide',
        'fadeinSpeed' : 'slow',
        'fadeoutSpeed' : '2000'
    });
});
//]]>
</script>
