Undo-Redo

What is Undo-Redo?

Undo-Redo is a simple library that allows you to customize the behavior of the standard undo and redo key operations (Cmd+Z and Cmd+Shift+Z).

How does it work?

Setup an environment for your undo-redo stack with the make() function

js

undoRedoStack.make(document.body, true);

Create an element that has undo and redo attributes that specify what happens when Cmd+Z and Cmd+Shift+Z are pressed.

js

//an example object
var obj = {
    undo: function() {
        document.body.removeChild(elem);
        return true;
    },
    redo: function() {
        document.body.appendChild(elem);
        return true;
    }
};

Add this element to your undo-redo stack with the addUndoObject() function

js

undoRedoStack.addUndoObject(object);
