Description

Add a JavaScript file, setting or inline code to the page.

The behavior of this function depends on the parameters it is called with. Generally, it handles the addition of JavaScript to the page, either as reference to an existing file or as inline code. The following actions can be performed using this function:

• Add a file ('core', 'module' and 'theme'): Adds a reference to a JavaScript file to the page. JavaScript files are placed in a certain order, from 'core' first, to 'module' and finally 'theme' so that files, that are added later, can override previously added files with ease.

• Add inline JavaScript code ('inline'): Executes a piece of JavaScript code on the current page by placing the code directly in the page. This can, for example, be useful to tell the user that a new message arrived, by opening a pop up, alert box etc.

• Add settings ('setting'): Adds a setting to Drupal's global storage of JavaScript settings. Per-page settings are required by some modules to function properly. The settings will be accessible at Drupal.settings.
