A JavaScript API that defines a friendly and browser-consistent content editable interface.
Editable is built for block level elements containing only phrasing content. This normally means p
, h1
-h6
, blockquote
etc. elements. This allows editable to be lean and mean since it is only concerned with formatting and not with layouting.
We made editable.js to support our vision of online document editing. Have a look at livingdocs.io.
Via npm:
npm install --save upfront-editable jquery
jQuery is a peerDependency, so you need to install it alongside editable.js. You can either require('upfront-editable')
or find a prebuilt file in the npm bundle dist/editable.js
. The required module will automatically pick up your jQuery
, while the built version expects it as a global variable.
You can check out a simple demo on the website. It features a formatting toolbar and the default insert, split and merge behavior that allow to add and remove content blocks like paragraphs easily.
- focus
Fired when an editable element gets focus. - blur
Fired when an editable element loses focus. - selection
Fired when the user selects some text inside an editable element. - cursor
Fired when the cursor position changes. - change
Fired when the user has made a change. - clipboard
Fired forcopy
,cut
andpaste
events. - insert
Fired when the user pressesENTER
at the beginning or end of an editable (For example you can insert a new paragraph after the element if this happens). - split
Fired when the user pressesENTER
in the middle of an element. - merge
Fired when the user pressedFORWARD DELETE
at the end orBACKSPACE
at the beginning of an element. - switch
Fired when the user pressed anARROW KEY
at the top or bottom so that you may want to set the cursor into the preceding or following element. - newline
Fired when the user pressesSHIFT+ENTER
to insert a newline.
To make an element editable:
var editable = new Editable()
editable.add($elem)
In a selection
event you get the editable element that triggered the event as well as a selection object. Through the selection object you can get information about the selection like coordinates or the text it contains and you can manipulate the selection.
In the following example we are going to show a toolbar on top of the selection whenever the user has selected something inside of an editable element.
editable.selection((editableElement, selection) => {
if (!selection) return toolbar.hide()
// get coordinates relative to the document (suited for absolutely positioned elements)
const coords = selection.getCoordinates()
// position toolbar
const top = coords.top - toolbar.outerHeight()
const left = coords.left + (coords.width / 2) - (toolbar.outerWidth() / 2)
toolbar.css({top, left}).show()
})
We haven't got around to make this documentation comprehensive enough. In the meantime you can find the API methods in src/core.js and the default implementation in src/default-behavior.js.
To find out what you can do with the the editable.js cursor
and selection
objects see src/cursor.js and src/selection.js.
