If you want to customize the toolbar to fit your own project, you can instanciate Pen constructor with an options object like #1.3: init with options:

2.1 Fallback for old browser

You can set defaults.textarea to a piece of HTML string, by default, it's <textarea name="content"></textarea>。This will be set as innerHTML of your #editor.

2.2 Change the editor class

Pen will add .pen to your editor by default, if you want to change the class, make sure to replace the class name pen to your own in src/pen.css.

2.3 Enable debug mode

If options.debug is set to true, Pen will output logs to the Console of your browser.

2.4 Customize the toolbar

You can set options.list to an Array, add the following strings to make your own:

blockquote, h2, h3, p, pre: create a tag as its literal meaning
insertorderedlist: create an ol>li list
insertunorderedlist: create a ul>li list
indent: indent list / blockquote block
outdent: outdent list / blockquote block
bold: wrap the text selection in a b tag
italic: wrap the text selection in an i tag
underline: wrap the text selection in a u tag
createlink: insert link to the text selection
inserthorizontalrule: insert a hr tag

By default, Pen will prevent unsafe page redirect when editing, to shut down it, specific options.stay to false.

NOTE: if defaults.debug is set to true and default.stay is not set: defaults.stay == !defaults.debug.

2.6 Disable and Re-enable editor

You can disable the pen editor by call destroy() method of the var pen = new Pen(options) object. like:

pen.destroy(); // return itself

And, there's a corresponding method called rebuild() to re-enable the editor:

pen.rebuild(); // return itself
