Adding JavaScript
This chunk should describe in detail how to add JavaScript to the head of a template using the Joomla! 1.5 API calls. It should be aimed at people who have only minimal knowledge of PHP, HTML and JavaScript.
Add the following code to have the javascript library /media/system/js/sample.js included in your template.
<?php $document = &JFactory::getDocument(); $document->addScript( '/media/system/js/sample.js' ); ?>
Explanation
Ultimately you are trying to have the resulting HTML page have in the <head> ... </head> area have a javascript include:
For Example:
<script type="text/javascript" src="/media/system/js/sample.js"></script>
Ensure that the javascript you want to include is in the directory, from the above example:
/media/system/js/sample.js
When you are able to load both your page and see the <script> tag in the <head> area, and be able to load the javascript from the address
Again, using the example:
http://www.example.com/media/system/js/sample.js
Then the script is integrated into your page, and you can proceed to using javascript in your HTML.
Do not directly add the <script> to your template's index.php.
The code will insert the the <script> line where your index.php has the following line:
<jdoc:include type="head" />
Add this PHP code to your page, in the head, or next to the javascript code you will use, depending on your preference.
<?php $document = &JFactory::getDocument(); $document->addScript( '/media/system/js/sample.js' ); ?>
Reload your template and view the page, and ensure that the sample.js is included in the <head>
Adding Javascript Files Using JHTML
You may also use the JHTML script method to add a javascript file to the head of your document.
<?php $filename = 'path/to/file/filename.js'; JHTML::script($filename); ?>
