Recently I was developing a component for a client and needed to add some specific javascript functionality for that page only.

To save from adding it to your template, it is possible to include the javascript for that component or view only.

This can be done by using the following code:

1
2
3

$document->addScript("path/to/script.js");
$document->addStyleSheet("path/to/style.css");
 

This will increase your joomla templates load speed, which is crucial for good search engine rankings.
