Advanced tools
This is a clone of medium.com inline editor toolbar.
MediumEditor has been written using vanilla JavaScript, no additional frameworks required.

demo: http://daviferreira.github.io/medium-editor/
Via bower:
Run in your console: bower install medium-editor
Manual installation:
Download the latest release and attach medium editor's stylesheets 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
<script src="js/medium-editor.js"></script>
You can now instantiate a new MediumEditor object:
<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);
{'bold': '<b>b</b>', 'italic': '<i>i</i>'}
. Default: falseleft
|center
|right
- Aligns the toolbar relative to the medium-editor element.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
});
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:
Check out the Wiki page for a list of available themes: https://github.com/daviferreira/medium-editor/wiki/Themes
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
Patrick Stillhart developed a new and improved way to add buttons to our toolbar. With it you can add HTML or javascript buttons. Check it out at:
https://github.com/arcs-/MediumButton
To add additional functions that are not supported by the native browser API you can write extensions that are then integrated into the toolbar. The Extension API is currently unstable and very minimal.
An extension is an object that has essentially three functions getButton
, getForm
and checkState
.
getButton
is called when the editor is initialized and should return an element that is integrated into the toolbar.
Usually this will be a <button>
element like the ones Medium Editor uses. All event handling on this button is
entirely up to you so you should either keep a reference or bind your eventhandlers before returning it. You can
also return a HTML-String that is then integrated into the toolbar also this is not really useful.
getForm
is called when the editor is initialized and should return an element that is integrated into the toolbar.
Usually this will be a <div>
element that would contain some input
elements. Handling the saving and canceling of the form is entirely up to you so you should either keep a reference or bind your eventhandlers before returning it.
checkState
is called whenever a user selects some text in the area where the Medium Editor instance is running. It's
responsability is to toggle the current state of the button. I.e. marking is a on or off. Again the method on how
determine the state is entirely up to you. checkState
will be called multiple times and will receive a DOM Element
as parameter.
Properties
parent
add this property to your extension class constructor and set it to true
to be able to access the Medium Editor instance through the base
property that will be set during the initialization
hasForm
add this property to your extension class constructor and set it to true
to tell Medium Editor that your extension contains a form. Medium editor will handle opening the form for you on your extension's button click.
A simple example the uses rangy and the CSS Class Applier Module to support highlighting of text:
rangy.init();
function Highlighter() {
this.button = document.createElement('button');
this.button.className = 'medium-editor-action';
this.button.textContent = 'H';
this.button.onclick = this.onClick.bind(this);
this.classApplier = rangy.createCssClassApplier("highlight", {
elementTagName: 'mark',
normalize: true
});
}
Highlighter.prototype.onClick = function() {
this.classApplier.toggleSelection();
};
Highlighter.prototype.getButton = function() {
return this.button;
};
Highlighter.prototype.checkState = function (node) {
if(node.tagName == 'MARK') {
this.button.classList.add('medium-editor-button-active');
}
};
var e = new MediumEditor('.editor', {
buttons: ['highlight', 'bold', 'italic', 'underline'],
extensions: {
'highlight': new Highlighter()
}
});
A simple example that uses the parent
attribute:
function Extension() {
this.parent = true;
this.button = document.createElement('button');
this.button.className = 'medium-editor-action';
this.button.textContent = 'X';
this.button.onclick = this.onClick.bind(this);
}
Extension.prototype.getButton = function() {
return this.button;
};
Extension.prototype.onClick = function() {
alert('This is editor: #' + this.base.id);
};
var one = new MediumEditor('.one', {
buttons: ['extension'],
extensions: {
extension: new Extension()
}
});
var two = new MediumEditor('.two', {
buttons: ['extension'],
extensions: {
extension: new Extension()
}
});
A simple table example that uses the hasForm
attribute:
function Table(options) {
this.parent = true;
this.hasForm = true;
this.options = options;
}
Table.prototype.init = function() {
this.createButton();
this.createForm();
};
Table.prototype.createButton = function() {
this.button = document.createElement('button');
this.button.className = 'medium-editor-action';
this.button.textContent = 'T';
if(this.base.options.buttonLabels === 'fontawesome'){
this.button.innerHTML = '<i class="fa fa-table"></i>';
}
this.button.onclick = this.onClick.bind(this);
};
Table.prototype.createForm = function() {
this.form = document.createElement('div'),
this.close = document.createElement('a'),
this.save = document.createElement('a'),
this.columnInput = document.createElement('input'),
this.rowInput = document.createElement('input');
this.close.setAttribute('href', '#');
this.close.innerHTML = '×';
this.close.onclick = this.onClose.bind(this);
this.save.setAttribute('href', '#');
this.save.innerHTML = '✓';
this.save.onclick = this.onSave.bind(this);
this.columnInput.setAttribute('type', 'text');
// Add the input CSS class for correct styling
this.columnInput.className = 'medium-editor-toolbar-input';
this.columnInput.setAttribute('placeholder', 'Column Count');
this.rowInput.setAttribute('type', 'text');
// Add the input CSS class for correct styling
this.rowInput.className = 'medium-editor-toolbar-input';
this.rowInput.setAttribute('placeholder', 'Row Count');
this.form.appendChild(this.columnInput);
this.form.appendChild(this.rowInput);
this.form.appendChild(this.save);
this.form.appendChild(this.close);
};
Table.prototype.getButton = function() {
return this.button;
};
Table.prototype.getForm = function() {
return this.form;
};
Table.prototype.onClick = function() {
this.columnInput.value = this.options.defaultColumns;
this.rowInput.value = this.options.defaultRows;
};
Table.prototype.onClose = function(e) {
e.preventDefault();
this.base.hideForm(this.form);
};
Table.prototype.onSave = function(e) {
e.preventDefault();
var columnCount = this.columnInput.value;
var rowCount = this.rowInput.value;
var table = this.createTable(columnCount, rowCount);
this.base.pasteHTML(table.innerHTML);
this.base.hideForm(this.form);
};
// Create the table element.
Table.prototype.createTable = function(cols, rows) {
var table = document.createElement('table'),
header = document.createElement('thead'),
headerRow = document.createElement('tr'),
body = document.createElement('tbody'),
wrap = document.createElement('div');
for (var h = 1; h <= cols; h++) {
var headerCol = document.createElement('th');
headerCol.innerHTML = '...';
headerRow.appendChild(headerCol);
}
header.appendChild(headerRow);
for (var r = 1; r <= rows; r++) {
var bodyRow = document.createElement('tr');
for (var c = 1; c <= this.options.defaultColumns; c++) {
var bodyCol = document.createElement('td');
bodyCol.innerHTML = '...';
bodyRow.appendChild(bodyCol);
}
body.appendChild(bodyRow);
}
table.appendChild(header);
table.appendChild(body);
wrap.appendChild(table);
return wrap;
};
// When creating your Medium Editor
var editor = new MediumEditor('.editable', {
buttons: ['table'],
extensions: {
'table': new Table({
defaultColumns: 3,
defaultRows: 2
}),
});
