Simplifies the process of selecting a popup window (and does not offer functionality beyond what
selectWindow()already provides).
windowIDis either not specified, or specified as "null", the first non-top window is selected. The top window is the one that would be selected by
selectWindow()without providing a
windowID. This should not be used when more than one popup window is in play.
windowIDas the following in order: 1) the "name" of the window, as specified to
window.open(); 2) a javascript variable which is a reference to a window; and 3) the title of the window. This is the same ordered lookup performed by
selectWindow.
