Redirecting NN6 events The mechanism for sending an event to an object outside the normal propagation pattern in NN6 is similar to that of IE4+, although with different syntax. In place of the IE4+ fireEvent() method, NN6 uses the W3C DOM dispatchEvent() method. The sole parameter of the method is an event object, such as the current event object. Listing 29-9 is the same as the IE4+ Listing 29-6, but with just a few modifications to run in the NN6 event model. Notice that the dispatchEvent() method passes the current event object as its sole parameter. Listing 29-9: Cancelling and Redirecting Events in NN6+
