Sommige web tuistes verander die venster fokus op hul eie deur gebruik te maak van window. focus (). Dit het tot gevolg dat die venster na vore geskuif sal word, en dit onderbreek dus die aksie waarmee die gebruiker besig was op daardie stadium. Hierdie opsie spesifiseer hoe dit hanteer moet word.
Some websites set the focus to their browser window on their own by using window. focus(). This usually leads to the window being moved to the front interrupting whatever action the user was dedicated to at that time. This option specifies the treatment of such attempts.
