directories, locationbar, menubar, personalbar, scrollbars, statusbar, toolbar | NN 4 IE n/a DOM n/a
These objects belong to the window object and represent portions of the "chrome" surrounding the content area of the browser window (the directories object is new for Netscape 6). With signed scripts in Navigator 4 or later (and the user's permission), you can dynamically hide and show these elements in a browser window. These features can also be turned off via the third parameter of the window.open( ) method, but only when generating a new window. To change the visibility of these items in an existing window, signed scripts are required. Internet Explorer has no equivalent functionality for a window that is already open.
