Tak\u017ee o co jde, jak na to. V b\u011b\u017en\u00e9m formul\u00e1\u0159i, kter\u00fd pot\u0159ebujete ochr\u00e1nit, p\u0159idejte dal\u0161\u00ed INPUT, nazv\u011bte ho t\u0159eba „antisp“ a napozicujte ho absolutn\u011b n\u011bkam pry\u010d ze str\u00e1nky, aby neru\u0161il a nep\u0159ek\u00e1\u017eel. D\u00edky tomu ho b\u011b\u017en\u00fd u\u017eivatel webu – rozum\u011bj \u010dlov\u011bk – ani neuvid\u00ed a nebude ho tedy vypl\u0148ovat. Zat\u00edmco robot ho v k\u00f3du uvid\u00ed a vypln\u00ed. Pak jen sta\u010d\u00ed o\u0161et\u0159it situaci p\u0159i validaci hodnot tak, \u017ee neprojde formul\u00e1\u0159 s vypln\u011bn\u00fdm polem „antisp“ a m\u00e1te pokoj \ud83d\ude42<\/p>\n
