History Tracker

The Jspreadsheet History Tracker automatically records all modifications. So, Users can undo or redo actions with CTRL+Z and CTRL+Y, respectively.

If you are migrating from Version 9 or before

Starting with Version 10, JSS enhances change tracking by decoupling it from specific grid instances, allowing monitoring across all sheets. This upgrade aligns JSS with standard spreadsheet functionalities, supporting safer cross-worksheet activities and providing a detailed change history.

Documentation

Methods

The undo and redo methods are normally invoked by the CTRL+Z, CTRL+Y keyboard shortcut. The following methods can be called programmatically, as follows:

Method	Description
history.undo()	Undo the last spreadsheet changes. `jspreadsheet.history.undo() : void`
history.redo()	Redo the most recent spreadsheet changes. `jspreadsheet.history.redo() : void`
history.reset()	Remove all history entries. `jspreadsheet.history.reset() : void`

Advance usage

Method	Description
history(object)	Add a new entry on the history tracker. `jspreadsheet.history(changes: Object) : void`

Events

Events related to the history changes tracker.

Event	Description
onredo	`onredo(worksheet: Object, info: Object) : null` The info array contains all necessary information about the history and depends on which change was performed.
onundo	`onundo(worksheet: Object, info: Object) : null` The info array contains all necessary information about the history and depends on which change was performed.

Interface

Event	Description
index: number;	History index cursor
actions: [];	History items
cascade: boolean;	When true the next item is cascaded in the same existing history element

progress: string;	Tell if a history process is ongoing.

Release Notes

As previously mentioned, from version 10 the history tracker can register changes across all spreadsheets on the screen, regardless of the worksheet instance. Therefore, the syntax to access this feature need revision to the following:

Attribute	Description
worksheet.resetHistory()	Please use `jspreadsheet.history.reset()`
worksheet.setHistory()	Please use `jspreadsheet.history()`
