The JavaScript History object is a child of the Window object and holds information about the URLs visited before and after the current URL.

The object has the following methods and properties:

  • history.length - a property containing the numner of URLs held in the history.
  • history.go() - takes a postive or negative number as an argument to specify how many changes back or forward in the history to go. For example history.go(-4) is equivalent to pressing the Back buttonm in the browser 4 times.
  • history.back() - equivalent to pressing the browser Back button (loads the previous page from the history list).
  • history.forward() - equivalent to pressing the browser Forward button (loads the next page from the history if it exists).
