Well since the Ajax requests in Prototype will auto-eval the response,
you can modify the page without updating just one div. It's the route
I take most of the time.
Say you set it up like this:
new Ajax.PeriodicalUpdater('', '/some/url');
Then the response from /some/url could be:
$('some-element').blindUp({duration:0.5);
// wait for the blind up to complete before replacing the content
Element.update.delay(0.5, 'some-element', '<p>my new content</p>');
// wait for the blind up to complete, then wait a 10th of a second longer
Element.blindDown.delay(0.6, 'some-element', {duration:0.5});
You get the idea. I find it more flexible and convenient than updating
just a single element. You could alternatively call into some
predefined object/method to do this work.
Some people might be opposed to this approach, but it works.
