Key points (tl;dr):
- Using the
.bind()method is very costly as it attaches the same event handler to every item matched in your selector.
- You should stop using the
.live()method as it is deprecated and has a lot of problems with it.
.delegate()method gives a lot of “bang for your buck” when dealing with performance and reacting to dynamically added elements.
- That the new
.on()method is mostly syntax sugar that can mimic
.delegate()depending on how you call it.
- The new direction is to use the new
.onmethod. Get familiar with the syntax and start using it on all your jQuery 1.7+ projects.
