back( ) — NN 2 IE 3 DOM n/a
The basic action is to navigate to the previously viewed document,
similar to the click of the browser’s Back button. In Navigator 4, however, you can
direct the back( ) method to a specific window or
frame, thus bypassing the default behavior of the Back button. For example, repeated calls to
parent.otherFrame.history.back( ) eventually run
out of history for the frame and cease to do anything further. On the
other hand, repeated calls to top.history.back( )
are the same as clicking the Back
button, conceivably backing out of the frameset entirely if it
wasn’t the first document loaded in the current browser
session.
