Magento在产品页提供了一个简单的图片放大的功能，但效果不是很好，如果考虑使用放大镜来使用户查看产品的大图，可以考虑使用基于jQuery的插件，jqZoom便是一款优秀的放大镜插件，下面将介绍怎样把jqzoom集成到Magento中。

 

1 加载jQuery

因为jqZoom是基于jQuery的插件，所以我们需要在Magento中加载jQuery库，并下载jqZoom文件包，放在网站的根目录的js目录下，比如/js/jqzoom

 

2 建立模块

作为例子，我们在/app/code/local/MagentoBoy/Jqzoom目录下新建一个模块MagentoBoy_Jqzoom，并添加模块文件：

/app/etc/modules/MagentoBoy_Jqzoom.xml

 

<?xml version="1.0"?>

 <config>

  <modules>

   <MagentoBoy_Jqzoom>

    <active>true</active>

    <codePool>local</codePool>

   </MagentoBoy_Jqzoom>

  </modules>

 </config>

并添加配置文件

/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 添加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中添加layout文件

 

 

<config>

 <frontend>

  <layout>

   <updates>

    <jqzoom>

     <file>jqzoom.xml</file>

    </jqzoom>

   </updates>

  </layout>

 </frontend>

</config>

4 修改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="width: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">

 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>

清除缓存，刷新前台页面，当鼠标悬浮在产品图片上时可以看到产品的放大图。
