jquery reading notes –event attribute description
Event attributes in the jquery event are frequently ignored. Most of the time you really don't use it, but sometimes it still works. For example, the user's environment (whether shift etc is pressed) is known when triggered. Each browser has a different place for the event, and jquery standardizes the event so that it is safe to use.
