Navigator is the limiting factor here as it supports only a limited number of events on a limited number of elements. The table below is an ambitious attempt to summarize the events and target elements support in one or both browsers. Information listed in blue applies only to Netscape , information listed in red applies only to Microsoft , and information in black applies to both.
User removes input focus from window, frame, or form.
User changes value of field. As data is transmitted from a source object this event periodically triggers. Each trigger signals that new data has arrived from the source. The dataset reflected via its source object has changed such as when the dataset initially becomes available or the object is altered to reflect a new dataset. The dataset bound to a source object has completed transfer, either successfully or unsuccessfully.
