Adding external JavaScript file to Magento

How to add external JavaSc开发者_StackOverflow社区ript file to Magento, so it's code would be included on every frontend page?

To add an external JS without any problem use this:

<reference name="head">
   <block type="core/text" name="google.cdn.jquery">
      <action method="setText">
        <text>
           <![CDATA[<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script><script type="text/javascript">jQuery.noConflict();</script>]]>
        </text>
      </action>
   </block>
</reference>

Put the JS file somewhere into the "js" folder, and in the XML layout you can include it with:

    <reference name="head">
        <action method="addJs"><script>folder/file.js</script></action>
    </reference>

Hope that helps.

Edit: You can also do it in your block:

    protected function _prepareLayout()
    {
        $this->getLayout()->getBlock('head')->addJs('path/from/js/folder/to/your/file.js');

        return parent::_prepareLayout();
    }

You can use Inchoo_Xternal extension. So you can do something like this:

<layout version="0.1.0">
    <default>
            <reference name="head">
                <action method="addItem"><type>external_css</type><name>http://developer.yahoo.com/yui/build/reset/reset.css</name><params/></action>
                <action method="addItem"><type>external_js</type><name>http://yui.yahooapis.com/2.8.2r1/build/yahoo-dom-event/yahoo-dom-event.js</name><params/></action>
                <action method="addExternalItem"><type>external_js</type><name>http://yui.yahooapis.com/2.8.2r1/build/imageloader/imageloader-min.js</name><params/></action>
                <action method="addExternalItem"><type>external_css</type><name>http://yui.yahooapis.com/2.8.2r1/build/fonts/fonts-min.css</name><params/></action>
            </reference>
    </default>
    <catalog_product_view>
        <reference name="head">
                <action method="removeItem"><type>external_css</type><name>http://developer.yahoo.com/yui/build/reset/reset.css</name><params/></action>
                <action method="removeItem"><type>external_js</type><name>http://yui.yahooapis.com/2.8.2r1/build/yahoo-dom-event/yahoo-dom-event.js</name><params/></action>
                <action method="removeExternalItem"><type>external_js</type><name>http://yui.yahooapis.com/2.8.2r1/build/imageloader/imageloader-min.js</name><params/></action>
                <action method="removeExternalItem"><type>external_css</type><name>http://yui.yahooapis.com/2.8.2r1/build/fonts/fonts-min.css</name><params/></action>
            </reference>
    </catalog_product_view>
</layout>

Here you can find more info about this.

<block type="core/text" name="jquery">
    <action method="setText">
        <text>
            <![CDATA[<script src="http://ajax.aspnetcdn.com/ajax/jquery.validate/1.9/jquery.validate.min.js?ver=3.9.2"></script>]]>
        </text>
    </action>
</block>

Create/edit the following:

app/design/frontend/PATH/TO/YOURTHEME/layout/local.xml

Make it look like so--should be self explanatory...

<!-- Add an EXTERNAL stylesheets  -->
<action method="addLinkRel"><rel>stylesheet</rel><href>https://fonts.googleapis.com/css?family=Roboto+Condensed:300italic,400,300,700|Open+Sans:300italic,400,300</href></action>

<!--  Add an EXTERNAL javascript  -->
<action method="addLinkRel"><rel>text/javascript</rel><href>https://maxcdn.bootstrapcdn.com/bootstrap/3.2.0/js/bootstrap.min.js</href></action>

<!-- Add stylesheets from your local theme directory located in skin/frontend/ -->
<action method="addCss"><stylesheet>css/styles.css</stylesheet></action>

<!-- Add javascript from your local theme directory located in skin/frontend/ -->
<action method="addJs"><script>bootstrap.min.js</script></action>

Work fine with 2.1.7

app/design/frontend/PATH/TO/YOURTHEME/layout/default_head_blocks.xml

<?xml version="1.0"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
    <head>
        <css src="css/bootstrap.min.css" />
        <css src="css/YOUR.css" order="99" />
        <link src="js/jquery.js" />
        <link src="js/bootstrap.js" />
        <link src="js/YOUR.js" />
    </head>
</page>

Method "addItem" and type "link_rel" to add external css file from page.xml

<action method="addItem"><type>link_rel</type>  <name>//vjs.zencdn.net/4.12/video-js.css</name><params>rel="stylesheet"</params></action>

None of the methods above worked for me because the script was not hosted on the same domain as the website and had to be controlled using a config variable.

This was my solution:

    /** @var Mage_Core_Model_Layout $layout */
    $layout = Mage::getSingleton('core/layout');

    /** @var Mage_Core_Block_Text $block */
    $block = $layout->createBlock('Mage_Core_Block_Text', $name);

    $block->setText('<script type="text/javascript" src="'.$url.'"></script>');

    /** @var Mage_Page_Block_Html_Head $head */
    $head = $layout->getBlock('head');

    $head->append($block);

I did this in an observer observing controller_action_layout_generate_blocks_after
