Jose Galdamez 17 December 2011 I had no clue about the on() method in v1.7. After seeing it in use here it definitely makes more sense to attach event handlers to parent elements as you did in your table example. In your section on DOM manipulation, are you also implying that it’s faster to prepend/append strings as opposed to DOM nodes? I’ve heard the former is faster, but never actually done any speed tests myself. I noticed one small typo. document.getElementsByTagname should be document.getElementsByTagName (capitalize the “n” in “Name”). Excellent post!
