queue_js_url — Add a JavaScript file to the current page by URL.
Summary
- queue_js_url($url, $options = array())
Add a JavaScript file to the current page by URL.
The script link will appear in the head element. This needs to be called either before head() or in a plugin_header hook.
- Parameters:
$url –
$options (
array) – An array of options.
Usage
head_js actually outputs the scripts. All themes should already call head_js themselves,
so you can just use the queue functions.
If writing a theme, queue_js_* functions must be called before the call to head_js. If writing a plugin,
you make these calls within the admin_head or public_head hooks.
The $options array is passed as the $attrs parameter to the
Zend Framework headScript
helper. This can be used to set some attributes on the <script> tag as
well as to enable some specific functionality of the ZF helper like IE
conditional comments.
Examples
Use to load external javascript files, such as the jquery library.
<?php queue_js_url('//ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js'); ?>
