script(mixed $url, mixed $options)

Creates link(s) to a javascript file. If key inline is set to false in $options, the link tags are added to the $scripts_for_layout variable which you can print inside the head tag of the document.

Include a script file into the page. $options['inline'] controls whether or not a script should be returned inline or added to $scripts_for_layout. $options['once'] controls, whether or not you want to include this script once per request or more than once.

You can also use $options to set additional properties to the generated script tag. If an array of script tags is used, the attributes will be applied to all of the generated script tags.

This method of javascript file inclusion assumes that the javascript file specified resides inside the /app/webroot/js directory.

<?php echo $this->Html->script('scripts'); ?> 

1. <?php echo $this->Html->script('scripts'); ?>

Will output:

<script type="text/javascript" href="/js/scripts.js"></script>

You can link to files with absolute paths as well to link files that are not in app/webroot/js

<?php echo $this->Html->script('/otherdir/script_file'); ?> 

1. <?php echo $this->Html->script('/otherdir/script_file'); ?>

The first parameter can be an array to include multiple files.

<?php echo $this->Html->script(array('jquery','wysiwyg','scripts')); ?>

1. <?php echo $this->Html->script(array('jquery','wysiwyg','scripts')); ?>

Will output:

<script type="text/javascript" href="/js/jquery.js"></script>
<script type="text/javascript" href="/js/wysiwyg.js"></script>
<script type="text/javascript" href="/js/scripts.js"></script>
