textarea: button to trigger native undo/redo

Question

I have a textarea. It has default undo/redo functionality, either with ctrl-z/y or by right-clicking and choosing copy/paste.

I want to create an undo/redo button and trigger the native undo/redo. I'm not sure how to trigger this. (Was surprised that my users don't know ctrl-z)

Answer 1

You can use document.execCommand to achieve this functionallity. It is used by some HTML-editors.

execCommand compatibility

And by now, this is deprecated, and should not be used.
