I know this is a Perl list but many Perl programmers know more than one
I have a JS question and don't know where to find the answer. I want to
implement an "Undo" for a dynamic change to a page.
Please respond off list if you can help me.
Basically, I'm sorting a list with JS. It's a bullet list, converted into
an array for sorting and then back to replace the original bullet list.
I want to save the original list object or array or whatever is most
convenient before the first sort so I can put up a "put it back" button or
link. I prefer not to get involved with Cookies.
Workaround: I know I can just reload the page but that changes position
and also takes more time.
Does anyone know of a convenient way to stash a copy of the array, or the
list object itself, grabbed originally with
var theList = document.getElementById(ListHandle);
into a variable that will still be there when I come back the next call
to the JS?
