Carousel

He kiʻi kiʻiʻoniʻoni no ka holo kaʻa ʻana ma waena o nā mea—nā kiʻi a i ʻole nā ​​kiʻi paheʻe o ke kikokikona—e like me ka carousel.

Pehea e hana ai

ʻO ka carousel kahi kiʻi kiʻiʻoniʻoni no ka holo kaʻa ʻana ma waena o nā ʻike, i kūkulu ʻia me CSS 3D transforms a me kahi hapa o JavaScript. Hoʻohana ia me nā kiʻi, kikokikona, a i ʻole markup maʻamau. Loaʻa pū kekahi i ke kākoʻo no nā mana mua / aʻe a me nā hōʻailona.

Ma nā polokalamu kele pūnaewele kahi i kākoʻo ʻia ai ka API Visibility ʻAoʻao , e pale ka carousel i ka paheʻe ʻana ke ʻike ʻole ʻia ka ʻaoʻao pūnaewele e ka mea hoʻohana (e like me ke ʻano ʻole o ka ʻaoʻao pūnaewele, hoʻemi ʻia ka puka aniani, a pēlā aku).

E ʻoluʻolu e ʻoluʻolu ʻaʻole kākoʻo ʻia nā carousels pūnana, a ʻaʻole kūlike nā carousels i nā kūlana hiki ke loaʻa.

ʻO ka hope, inā ʻoe e kūkulu nei i kā mākou JavaScript mai ke kumu, ponoutil.js ia .

Laʻana

ʻAʻole hana maʻamau nā Carousels i nā ana paheʻe. No laila, pono paha ʻoe e hoʻohana i nā pono hana hou a i ʻole nā ​​​​ʻano maʻamau i ka nui o ka ʻike. ʻOiai ke kākoʻo nei nā carousels i nā mana a me nā hōʻailona o mua/hope aku, ʻaʻole koi ʻia lākou. Hoʻohui a hoʻopilikino e like me kou manaʻo pono.

Pono .activee hoʻohui ʻia ka papa i kekahi o nā paheʻe i ʻole e ʻike ʻia ka carousel. E ʻoluʻolu hoʻi e kau i kahi id kū hoʻokahi ma ka .carouselno nā mana koho, ʻoi aku ka nui inā ʻoe e hoʻohana nei i nā carousels he nui ma ka ʻaoʻao hoʻokahi. Pono nā mea hoʻomalu a me nā mea hōʻike e loaʻa i kahi data-targetʻano (a i ʻole hrefno nā loulou) i kūpono i ka id o ka .carouselmea.

Paheʻe wale

Eia kahi carousel me nā paheʻe wale nō. E hoʻomaopopo i ka loaʻa ʻana o nā kiʻi carousel .d-blocka .w-100ma luna o nā kiʻi carousel e pale ai i ka hoʻolikelike kiʻi paʻamau.

$('.carousel').carousel()

Nā koho

Hiki ke hāʻawi ʻia nā koho ma o nā ʻikepili a i ʻole JavaScript. No nā ʻano ʻikepili, e hoʻopili i ka inoa koho i data-, e like me ka data-interval="".

Nā ʻano hana

.carousel(options)

Hoʻomaka ka carousel me nā koho koho objecta hoʻomaka i ka holo kaʻa i nā mea.

$('.carousel').carousel({
  interval: 2000
})

.carousel('cycle')

Kaʻapuni i nā mea carousel mai ka hema a i ka ʻākau.

.carousel('pause')

Hoʻopau i ka carousel mai ka holo paikikala ma nā mea.

.carousel(number)

Hoʻololi i ka carousel i kahi kiʻi kikoʻī (ma muli o 0, e like me kahi array). E hoʻi i ka mea kelepona ma mua o ka hōʻike ʻia ʻana o ka mea i manaʻo ʻia (ʻo ia hoʻi ma mua o ka hiki ʻana o ka slid.bs.carouselhanana).

.carousel('prev')

Hoʻoholo i ka mea mua. E hoʻi i ka mea kelepona ma mua o ka hōʻike ʻia ʻana o ka mea mua (ʻo ia hoʻi ma mua o ka hiki ʻana o ka slid.bs.carouselhanana).
