magento 在全站或者某页面增加外联js或者css的方法

1，在整站末尾增加外联资源

　　找到当前主题的布局文件cms.xml，在<default></default>添加如下代码：

        <reference name="before_body_end">
            <!-- add another block of type page/html_head to have all the great functionality to add/remove css and js stuff -->
            <!-- it is important to set your own template, because the head block has a defined default template page/head.phtml which has all the stuff of the head. Using this will bring a lot of problems -->
            <block type="page/html_head" name="scripts_in_footer" template="country/scriptscss.phtml">
                <!-- add whatever you want as you are used to in the head via the standard magento api -->
                <action method="addItem"><type>skin_js</type><name>country/country.js</name></action>
            </block>
        </reference>

2，在某个页面添加外联资源

 　　找到当前页对应moudel的layout文件，在对应控制器中添加上述代码：

　　

    <country_index_index>
     
        <reference name="before_body_end">
            <!-- add another block of type page/html_head to have all the great functionality to add/remove css and js stuff -->
            <!-- it is important to set your own template, because the head block has a defined default template page/head.phtml which has all the stuff of the head. Using this will bring a lot of problems -->
            <block type="page/html_head" name="scripts_in_footer" template="country/scriptscss.phtml">
                <!-- add whatever you want as you are used to in the head via the standard magento api -->
                <action method="addItem"><type>skin_js</type><name>country/country.js</name></action>
            </block>
        </reference>

    </country_index_index>

3，新建template文件scriptscss.phtml，添加如下代码

　　

<?php // and to echo the whole stuff later in the template, you need to add the code, so the added js/Css files are echoed ?>
<?php echo $this->getCssJsHtml() ?>
<?php echo $this->getChildHtml() ?>

刷新页面，加载完成，主要涉及的是before_body_end块定义加载的位置，使用html_head块里面的方法添加资源到对应的页面上，
