How to load JS in Magento footer?

Sometimes it can be required to load JS in Magento footer. Trying to do you it you will get the following error:

Invalid method Mage_Page_Block_Html_Footer::addItem(Array ( [0] => skin_js [1] => js/fabric/tool/controller_tool.js ) )

By default Magento footer block is not designed to work with javascript. JS works only in header as this block is of type page/html_head which holds these methods

There are 3 ways how you could achieve your goal.

  1. The first option is to update layout as following:

<reference name="before_body_end"> <block type="core/template" name="controller_tool_javascript" template="fabric/tool/controller_tool_js.phtml"/> </reference>

Next create a fabric/tool/controller_tool_js.phtml file in your template folder with the following code:

<script type="text/javascript" src="<?php echo $this->getSkinUrl('js/fabric/tool/controller_tool.js') ?>"></script>

  1. The second would be to putting the JS <script src=...></script> tag inside a template (.phtmlfile) and include that as a core/template block:

<reference name="footer"> <block type="core/template" name="fabric_controller_tool_js" template="fabric/controller_tool_js.phtml" /> </reference>

  1.  And the third one is to add your JS code through a core/text block:

<reference name="footer"> <block type="core/text" name="fabric_controller_tool_js"> <action method="setText"> <text><![CDATA[<script src="/js/fabric/tool/controller_tool.js"></script>]]></text> </action> </block> </reference>
