edited

Listens on editable elements and calls back on significant changes

How does it work?

It listens on the events that could possibly be edits on the provided element and determines their edit type.

Edit Types

Edited supports the following edit types:

• Character addition
• Backward deletion
• Forward deletion
• Space
• Enter
• Paste
• Drop
• Cut (not yet implemented)

"Sensible" Edits

Edited does work to callback only on edits that you care about. Instead of 19 callbacks when the user types awesomesauce module, you get 3 callbacks. One for awesomesauce, one for the space, and another for module.

Specifically, when the Edit Type changes, then it is determined that a sensible edit was made and the provided callback is fired. For the paste and drop Edit Types, every edit counts as a sensible edit.

onAny

Optionally, a function can be provided, which will be called back on any edit (not just Sensible Edits).

This module may be useful for registering undo/redo points, resource–friendlier autosaves and probably more (register an issue describing your integration and I’ll mention it here).

Example

var Edited = require(‘edited’)

var onSensible = function () {
  // register undo point, autosave, etc
}

var onAny = function () {
  // this may also be useful
}

var edited = new Edited(someEditableElement, onSensible, onAny)

// benefit!

// in case you don’t require it any more
edited.detach() // and it will stop listening

The callbacks are called synchronously, before the native event (the edit) occurs.

The callbacks are called with the instance as this.

The provided editable element can be accessed as the element property of the instance.
