MediumEditor

This is a clone of medium.com inline editor toolbar.

Since I always had problems with bloated editors and I loved the simplicity of medium.com solution I've tried to implement their WYSIWYG approach with this script.

MediumEditor has been written using vanilla JavaScript, no additional frameworks required.

Tested on Google Chrome, Firefox and IE9+.

Basic usage

demo: http://daviferreira.github.io/medium-editor/

First, you need to attach medium editor's stylesheet to your page:

<link rel="stylesheet" href="css/medium-editor.css"> <!-- Core -->
<link rel="stylesheet" href="css/themes/default.css"> <!-- or any other theme -->

The next step is to reference the editor's script and instantiate a new MediumEditor object:

<script src="js/medium-editor.js"></script>
<script>var editor = new MediumEditor('.editable');</script>

The above code will transform all the elements with the .editable class into HTML5 editable contents and add the medium editor toolbar to them.

You can also pass a list of HTML elements:

var elements = document.querySelectorAll('.editable'),
    editor = new MediumEditor(elements);

IE9

If you want to support IE9, you will need to use a classList pollyfill, like Eli Gray's, available at https://github.com/eligrey/classList.js.

Initialization options

allowMultiParagraphSelection: enables the toolbar when selecting multiple paragraphs/block elements. Default: true
anchorInputPlaceholder: text to be shown as placeholder of the anchor input. Default: Paste or type a link
anchorPreviewHideDelay: time in milliseconds to show the anchor tag preview after the mouse has left the anchor tag. Default: 500
buttons: the set of buttons to display on the toolbar. Default: ['bold', 'italic', 'underline', 'anchor', 'header1', 'header2', 'quote']
buttonLabels: type of labels on the buttons. Values: 'fontawesome', {'bold': '<b>b</b>', 'italic': '<i>i</i>'}. Default: false
checkLinkFormat: enables/disables check for http on anchor links. Default: false
cleanPastedHTML: cleans pasted content from different sources, like google docs etc. Default: false
delay: time in milliseconds to show the toolbar or anchor tag preview. Default: 0
diffLeft: value in pixels to be added to the X axis positioning of the toolbar. Default: 0
diffTop: value in pixels to be added to the Y axis positioning of the toolbar. Default: -10
disableReturn: enables/disables the use of the return-key. You can also set specific element behavior by using setting a data-disable-return attribute. Default: false
disableDoubleReturn: allows/disallows two (or more) empty new lines. You can also set specific element behavior by using setting a data-disable-double-return attribute. Default: false
disableToolbar: enables/disables the toolbar, adding only the contenteditable behavior. You can also set specific element behavior by using setting a data-disable-toolbar attribute. Default: false
firstHeader: HTML tag to be used as first header. Default: h3
forcePlainText: Forces pasting as plain text. Default: true
placeholder: Defines the default placeholder for empty contenteditables. You can overwrite it by setting a data-placeholder attribute on your elements. Default: 'Type your text'
secondHeader: HTML tag to be used as second header. Default: h4
targetBlank: enables/disables target="_blank" for anchor tags. Default: false

Example:

var editor = new MediumEditor('.editable', {
    anchorInputPlaceholder: 'Type a link',
    buttons: ['bold', 'italic', 'quote'],
    diffLeft: 25,
    diffTop: 10,
    firstHeader: 'h1',
    secondHeader: 'h2',
    delay: 1000,
    targetBlank: true
});

Extra buttons

Medium Editor, by default, will show only the buttons listed above to avoid a huge toolbar. There are a couple of extra buttons you can use:

superscript
subscript
strikethrough
unorderedlist
orderedlist
pre
image (this simply converts selected text to an image tag)
indent (moves the selected text up one level)
outdent (moves the selected text down one level)

Themes

Check out the Wiki page for a list of available themes: https://github.com/daviferreira/medium-editor/wiki/Themes

API

.deactivate(): disables the editor
.activate(): re-activates the editor
.serialize(): returns a JSON object with elements contents

Capturing DOM changes

For observing any changes on contentEditable

$('.editable').on('input', function() {
  // Do some work
});

This is handy when you need to capture modifications other thats outside of key up's scope like clicking on toolbar buttons.

input is supported by Chrome, Firefox, IE9 and other modern browsers. If you want to read more or support older browsers, check Listening to events of a contenteditable HTML element and Detect changes in the DOM

Image Upload

Pavel Linkesch has developed a jQuery plugin to upload images following Medium.com functionality. Check it out at http://orthes.github.io/medium-editor-insert-plugin/

Angular directive

Thijs Wijnmaalen hacked together an AngularJS directive. Check it out at https://github.com/thijsw/angular-medium-editor

Development

MediumEditor development tasks are managed by Grunt. To install all the necessary packages, just invoke:

npm install

These are the available grunt tasks:

js: runs jslint and jasmine tests and creates minified and concatenated versions of the script;
css: runs autoprefixer and csslint
test: runs jasmine tests, jslint and csslint
watch: watch for modifications on script/scss files

The source files are located inside the src directory.
