I'll tidy up the undo code to make a nice plugin release out of it, but there
it is in case anyone wants to take a look at it now.
I'd be interested in any feedback on the issues I mentioned in my previous
message. (I'd mentioned saving the undo/redo queue in a
hidden form field so it survives a soft reload, but now that I look at the
code, it doesn't do that. Must have been something I was
thinking about doing. The code actually should work with either strings or
objects or any type as the undo queue entries.)
Interesting stuff Mike! I can imagine quite a few scenarios where that
could be used. For example I'm currently working on persisting the
treeview plugin in a cookie. Pushing my serialized form to the
undo-plugin would be really easy, and the persistence in a hidden field
may be even the more appropiate approach in same cases.
You could make it an actual plugin that must start with the two buttons
as the selected elements, something like this:
$.fn.undo = function() {
var $undoBtn = this.eq(0), undoBtn = this[0];
var $redoBtn = this.eq(1), redoBtn = this[1];
...
}
A bit of documentation about the options and the return value definitely
help a lot.
