One of the libraries leveraging event delegation is reglib. Another option might be the JQuery plugin LiveQuery and others. Starting from version 1.3 JQuery offers the methods “live” and “die” that provide some simple event delegation features.
These libraries attach event handlers to the document itself (since every element bubbles up there eventually) that choose the function to call based on the selector the event.target fits too. Even if this is not the optimal solution for every application, I hope you consider the use of event delegation on <tables> and <li> instead of attaching an eventhandler to every single row.
