Witam,
Na wordpressie używam wtyczki NextGEN gallery z efektem 'shutter'
NextGEN gallery - to wtyczka do tworzenia albumów, galerii zdjęć.
Efekt 'shutter' - to zamazanie strony w tle, a wrzucenie na pierwszy plan zdjęcia w dobrej ostrości.
Staram się wdrożyć własny scrollbar
Własny, czyli moja grafika pod strzałki.
Kod scrollbar-a wziąłem stąd: http://www.java2s.com/Code/JavaScript/GUI-Components/Customscrollbar2.htm
Problem polega na tym, że po wdrożeniu scrollbara 'shutter' przestaje działać i zdjęcie otwiera się na nowej stronie.
Diagnoza wykazała, że po zakomentowaniu linii kodu:
document.getElementById(root).innerHTML = buttons + document.getElementById(root).innerHTML;
a nawet po zmianie jej na:
document.getElementById(root).innerHTML = document.getElementById(root).innerHTML;
efekt 'shutter' przestaje działać.
Co dziwne samo wywołanie:
document.getElementById(root).innerHTML;
nie wyłącza efektu 'shutter'
Wiem, że powinienem poszukać czegoś w dokumentacji na temat document.getElementById(), ale mam nadzieję, że ktoś pomoże mi zaoszczędzić ten czas.
Mój przerobiony kod zamieszczam poniżej:
