I have an external database which lie aside my html , and i want access it by the way of  HTML5.just like this:

openDatabase("student", "1.0", "table student", 1024 * 1024, function (){});

but the system will detect the default folder of inner web db,how can I specify the path of database so I can access my own database .

Or ,mybe there is a way to get the path of the default folder of inner web db ,and I can move my own database into it then access it .

                          Any help is appreciate.
