Carousel

O se vaega fa'ata'ita'i mo le uila i elemene—ata po'o fa'ase'e o tusitusiga—pei o se carousel.

E faapefea ona galue

O le carousel o se faʻataʻitaʻiga mo le tietie uila i se faasologa o anotusi, fausia i le CSS 3D transforms ma sina JavaScript. E galue i se faasologa o ata, tusitusiga, poʻo faʻailoga masani. E aofia ai foʻi le lagolago mo faʻatonuga muamua / sosoʻo ma faʻailoga.

I su'esu'ega o lo'o lagolagoina ai le Itulau Visibility API , o le carousel o le a 'alofia le fa'ase'e pe a le va'aia e le tagata fa'aoga le itulau i luga ole laiga (pei o le taimi e le gaioi ai le itulau su'esu'e, fa'aitiitia le fa'amalama o le su'esu'ega, ma isi).

Fa'amolemole ia nofouta e le o lagolagoina fo'i ta'avale fa'amoe, ma e masani fo'i ona le ogatasi ma ta'iala fa'aoga.

Ma le mea mulimuli, afai o loʻo e fausiaina la matou JavaScript mai le puna, e manaʻomiautil.js .

Faataitaiga

E le otometi ona fa'avasega e ta'avale fa'ase'e fua. E pei o lea, atonu e te manaʻomia le faʻaogaina o mea faʻaoga faaopoopo poʻo sitaili masani e faʻatatau i le tele o mea. A'o lagolagoina e carousels pulega ma fa'ailoga muamua/so'o mai, e le'o mana'omia manino. Fa'aopoopo ma fa'avasega pe a e mana'o e fetaui.

E .activemana'omia le fa'aopoopoina o le vasega i se tasi o fa'ata'ita'i a leai o le a le mafai ona iloa le ta'avale. Ia mautinoa foi e seti se id tulaga ese i luga o le .carouselmo le pule faitalia, aemaise lava pe afai o loʻo e faʻaogaina le tele o carousels i luga o le itulau e tasi. O elemene fa'atonutonu ma fa'ailoga e tatau ona iai se data-targetuiga (po'o hrefso'otaga) e fetaui ma le id o le .carouselelemene.
