• LIVE DEMO: http://sofish.github.io/pen
• Markdown is supported
• Build status:

You can clone the source code from github, or using bower.

bower install pen

var editor = new Pen('#editor');

var editor = new Pen(document.getElementById('editor'));

var options = {
  editor: document.body, // {DOM Element} [required]
  class: 'pen', // {String} class of the editor,
  debug: false, // {Boolean} false by default
  textarea: '<textarea name="content"></textarea>', // fallback for old browsers
  list: ['bold', 'italic', 'underline'], // editor menu list
  linksInNewWindow: true // open hyperlinks in a new windows/tab
}

var editor = new Pen(options);

The following object sets up the default settings of Pen:

defaults = {
  class: 'pen',
  debug: false,
  textarea: '<textarea name="content"></textarea>',
  list: [
    'blockquote', 'h2', 'h3', 'p', 'insertorderedlist', 'insertunorderedlist',
    'indent', 'outdent', 'bold', 'italic', 'underline', 'createlink'
  ],
  stay: true,
  linksInNewWindow: false
}

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:

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.

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.

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

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
• insertimage: insert an image (img) tag

You can set options.titles to an object with properties that match the toolbar actions. The value of each property will be used as the title attribute on the icon. Most browsers will display the title attribute as a tooltip when the mouse hovers over the icon.

options.title = {
    'blockquote': 'Blockquote'
    'createlink': 'Hyperlink'
    'insertimage': 'Image'
}

If you are using Bootstrap or jQueryUI, you can standardize the tooltip style by adding $('i.pen-icon').tooltip() to your JavaScript.

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.

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

var pen = new Pen('#editor');

pen.destroy(); // return itself

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

pen.rebuild(); // return itself

It's an experimental feature

var pen = new Pen('#editor');

pen.toMd(); // return a markdown string

The syntax convertor will be enabled automatically by linking markdown.js after `pen.js:

<script src="src/pen.js"></script>
<script src="src/markdown.js"></script>

To use it, you can type action cmd + space key at a line start. like:

### This will create a h3 tag

The following cmds are allowed:

• Headings: type 1~6 # at the line start
• Unordered List: type - or *
• Ordered List: type 1.
• Code block: type ```
• Block Quote: type >
• Horizontal Rule: more than 3 -, *, . will create a <hr />, like ......
