JavaScript » Window » close

Syntax:

window.close( )

This method is used to close a specified window. If no window reference is supplied, the close() method will close the current active window. Note that this method will only close windows created using the open() method; if you attempt to close a window not created using open(), the user will be prompted to confirm this action with a dialog box before closing. The single exception to this is if the current active window has only one document in its session history. In this case the closing of the window will not require confirmation.
