Related Items:Dateobject. typeValue:String.Read-OnlyCompatibility:WinIE4+, MacIE4+, NN6+, Moz1+, Safari1+ You can find out what kind of event fired to create the current event object by way of thetypeproperty. The value is a string version of the event name just the name of the eventwithout the on prefix that is normally associated with event listener names in NN6+. Thisproperty can be helpful when you designate one event handler function to process differentkinds of events. For example, both the onmousedownand onclickevent listeners for anobject can invoke one function. Inside the function, a branch is written for whether the typecomes in as mousedownor click, with different processing for each event type. That is not toendorse such event handler function sharing, but be aware of this power should your scriptconstructions find the property helpful. This property and its values are fully compatible with the NN4 and IE4+ event models. Keyboard events in Safari 1.0 report their types as khtml_keydown, khtml_keypress, andkhtml_keyup, using the prefix referring to the name of the rendering engine on whichSafari is built. This is probably to avoid committing to an unfinished W3C DOM Level 3 key- board event specification. Related Items:All event handlers (Chapter 15). viewValue:Window object reference.Read-OnlyCompatibility:WinIE-, MacIE-, NN6+, Moz1+, Safari1+ The closest that the W3C DOM Level 2 specification comes to acknowledging the browserwindow is an abstract object called an abstract view(AbstractView class). The object s onlyproperty is a reference to the document that it contains the root document node thatyou ve come to know and love. User events always occur within the confines of one of theseviews, and this is reflected in the eventobject s viewproperty. NN6+ returns a reference tothe windowobject (which can be a frame) in which the event occurs. This reference allows anevent object to be passed to scripts in other frames and those scripts can then gain access tothe documentobject of the target element s window. Related Items:windowobject.
