I have a page starting out with:

After an AJAX call, the innerhtml is updated to:

where after the new content is loaded, I want to run

$(‘newDiv’).fade({ duration: 2.0, from: 1, to: 0 });

I can’t figure out how to set this up. Code examples or links to  
documentation would be nice… 🙂

I’m an idiot. A simple :onsuccess callback was all I needed.

But, on the upside, at the same time I figured out how insert
