Wtyczka na fajerwerki (Fireworks) na Invision Community

[Koziel]

Siemanko! Czy istnieje taka wtyczka na IPS Community Suite 4.3 na "fajerwerki"? Jeśli tak, to jak się nazywa? Czy może trzeba samemu sobie zrobić to w np. CSS i JS?

Nie ma. Kiedyś za górami za lasami używałem JS'a ogólnodostępnego.

@Pretty Little Psycho Eh.

JS wstawiłem do globalTemplate, za <!--ipsQueryLog-->, html wstawiamy tam gdzie chcemy, aby było to wyświetlane.

UPS, nie doczytałem. -,-

A jakiś przykład tego? Gdzie takie coś widziałeś?

@Weak. nie pisałem do Ciebie

Nie ma gotowej wtyczki.

Pewnie na ruskim forum to widział. Przykład: Fireworks

@Koziel Są za to świąteczne lampki
