History Module

The History module is responsible for handling undo and redo for Quill. It can be configured with the following options:

Configuration

delay

• Default: 1000

Changes occuring within the delay number of milliseconds are merged into a single change.

For example, with delay set to 0, nearly every character is recorded as one change and so undo would undo one character at a time. With delay set to 1000, undo would undo all changes that occured within the last 1000 milliseconds.

maxStack

• Default: 100

Maximum size of the history's undo/redo stack. Merged changes with the delay option counts as a singular change.

userOnly

• Default: false

By default all changes, whether originating from user input or programmatically through the API, are treated the same and change be undone or redone by the history module. If userOnly is set to true, only user changes will be undone or redone.

Example

const quill = new Quill('#editor', {
  modules: {
    history: {
      delay: 2000,
      maxStack: 500,
      userOnly: true
    },
  },
  theme: 'snow'
});

API

clear

Clears the history stack.

Methods

clear()

Examples

quill.history.clear();

cutoff

Normally changes made in short succession (configured by delay) are merged as a single change, so that triggering an undo will undo multiple changes. Using cutoff() will reset the merger window so that a changes before and after cutoff() is called will not be merged.

Methods

cutoff()

Examples

quill.history.cutoff();

undo

Undo last change.

Methods

undo()

Examples

quill.history.undo();

redo

If last change was an undo, redo this undo. Otherwise does nothing.

Methods

redo()

Examples

quill.history.redo();
