378Part IIIDocument Objects Referencedifferent document into a window, use the locationobject (see Chapter 17). The documentobject is described in detail in Chapter 18. Related Items:documentobject. eventValue:Object.Read/WriteCompatibility:WinIE4+, MacIE4+, NN-, Moz-, Safari1+ IE4+ and Safari treat the eventobject as a property of the windowobject. Navigator 4+ andthe W3C DOM (as well as Safari here, too) pass an instance of the Eventobject as an argu- ment to event handler functions. The connection with the windowobject is relatively inconse- quential, because all action involving the eventobject occurs in event handler functions. Theonly difference is that the object can be treated as a more global object when one event han- dler function invokes another. Instead of having to pass the eventobject parameter to thenext function, functions can access the eventobject directly (with or without the window. prefix in the reference). For complete details about the eventobject in all browsers, see Chapter 25.

The property provides a gateway between the current browser window and theapplication that acts as a host to the browser window component. With WinIE4+ acting as a component to the host operating system, the externalproperty canbe used to access several methods that influence behaviors outside of the browser. Perhapsthe three most useful methods to regular Web page scripters are AddDesktopComponent(), AddFavorite(), and NavigateAndFind(). The first two methods display the same kind ofalert dialog box that users get after making these choices from the browser or desktop menus, so that you won t be able to sneak your Web site onto desktops or Favorites listings withoutthe visitor s approval. Table 16-2 describes the parameters for these three methods.
