  1. How to access the length property in history object

Length of history

history.length tells how many items are in the history stack. By testing for this value, it's possible to determine if the user's start point was your page:

<!DOCTYPE HTML> <!--  j a va2 s  .c o  m-->
<html> 
    <body> 
        <script> 
            if (history.length == 0){ 
                document.writeln("0")
            } else{
                document.writeln("more than 0")
            }


        </script> 
    </body> 
</html>
