Properties
-
length This numeric property specifies the number of URLs in the browser’s history list. Since there is no way to determine the index of the currently displayed document within this list, knowing the size of this list is not particularly helpful.
Methods
-
back( ) Goes backward to a previously visited URL.
-
forward( ) Goes forward to a previously visited URL.
-
go( ) Goes to a previously visited URL.
Description
The History object represents the
browsing history of a window -- it maintains a list of recently
visited web pages. For security and privacy reasons, however, the
contents of this list are not accessible to scripts. Although scripts
cannot access the URLs represented by the History object, they can
use the length property to determine the number of
URLs in the list and the back( ),
forward( ), and go( ) methods
to cause the browser to revisit any of the URLs in the array.
Example
The following line performs the same action as clicking a browser’s Back button:
history.back( );
The following performs the same action as clicking the Back button twice:
history.go(-2);
