As browsers evolve into the fourth generation (IE4 and Netscape Communicator 4), the browser team encounters an interesting question: which part of the page will have a specific event? Imagine having a set of concentric circles on a piece of paper, if you put your finger on the center of the circle, then your finger is pointing not to a circle, but to a group of circles. The development teams of two companies are consistent in their view of browser events. If you click a button, you also click t
