4 * This is the HTML editor in WordPress. It can be attached to any textarea and will
5 * append a toolbar above it. This script is self-contained (does not require external libraries).
7 * Run quicktags(settings) to initialize it, where settings is an object containing up to 3 properties:
9 * id : 'my_id', the HTML ID of the textarea, required
10 * buttons: '' Comma separated list of the names of the default buttons to show. Optional.
11 * Current list of default button names: 'strong,em,link,block,del,ins,img,ul,ol,li,code,more,spell,close';
14 * The settings can also be a string quicktags_id.
16 * quicktags_id string The ID of the textarea that will be the editor canvas
17 * buttons string Comma separated list of the default buttons names that will be shown in that instance.

280 * Main API function for adding a button to Quicktags
282 * Adds qt.Button or qt.TagButton depending on the args. The first three args are always required.
283 * To be able to add button(s) to Quicktags, your script should be enqueued as dependent
284 * on "quicktags" and outputted in the footer. If you are echoing JS directly from PHP,
285 * use add_action( 'admin_print_footer_scripts', 'output_my_js', 100 ) or add_action( 'wp_footer', 'output_my_js', 100 )
287 * Minimum required to add a button that calls an external function:
288 * QTags.addButton( 'my_id', 'my button', my_callback );
289 * function my_callback() { alert('yeah!'); }
291 * Minimum required to add a button that inserts a tag:
292 * QTags.addButton( 'my_id', 'my button', '<span>', '</span>' );
293 * QTags.addButton( 'my_id2', 'my button', '<br />' );
295 * @param id string required Button HTML ID
296 * @param display string required Button's value="..."
297 * @param arg1 string || function required Either a starting tag to be inserted like "<span>" or a callback that is executed when the button is clicked.
298 * @param arg2 string optional Ending tag like "</span>"
299 * @param access_key string optional Access key for the button.
300 * @param title string optional Button's title="..."
301 * @param priority int optional Number representing the desired position of the button in the toolbar. 1 - 9 = first, 11 - 19 = second, 21 - 29 = third, etc.
302 * @param instance string optional Limit the button to a specifric instance of Quicktags, add to all instances if not present.
303 * @return mixed null or the button object that is needed for back-compat.
