Use of document.load forbidden on Documents that come from other Windows. Only the Window in which a Document was created is allowed to call .load on that Document. Preferably, use XMLHttpRequest instead.
Hujjatlarda boshqa Windows’dan kelgan document.load’dan foydalanish ta’qiqlangan. Faqat "Hujjat" yaratgan oynaga "Hujjatda"  .load’ni chaqirishga ruxsat berilgan. O‘rniga XMLHttpRequest’dan foydalanish tavsiya qilinadi.
