Question, Let's say you had a div / table with multiple inputs, do you manually set the onblur for each input or "observe" from the form, div?


It's kind of risky to try to observe the blur event from above the element, because IE has serious trouble with bubbling form inputs. The Form.Element.Observer and Form.Observer frameworks are there to work around this problem. Have a look through the documentation.

If you wanted to do this yourself in an unobtrusive manner, you could set an observer on each element long-hand, like this:
document.observe('dom:loaded', function(){
        ['field1','field2','field3'].each(function(elm){
                $(elm).observe('blur',function(evt){
                        //do your stuff here,
                        //this == your element,
                        //evt == the blur event
                });
        });
});
