I'm looking for some kind of `change` event but for non-forms elements.

Problem:  

I have a `table` where `tr` tags are changing dynamicly by another script. `Tr` elements are changing from `display:block` to `display:none` or vice versa.

And I need something like this:

event will listing for change of any `tr` in my `table` (not matter to display `none` or `block`) and after any change the script will check if all `tr`s are set as `display:none` and if true then do something.
