Uburyo ikora

Carousel ni slide yo gusiganwa ku magare binyuze mu ruhererekane rw'ibirimo, yubatswe na CSS 3D ihindura hamwe na JavaScript. Ikorana nuruhererekane rwamashusho, inyandiko, cyangwa ikimenyetso cyihariye. Harimo kandi inkunga kubanza / ubutaha kugenzura n'ibipimo.

Mucukumbuzi aho Page Visibility API ishyigikiwe, karuseli izirinda kunyerera mugihe urubuga rutagaragara kubakoresha (nkigihe iyo tab ya mushakisha idakora, idirishya rya mushakisha riba ryaragabanutse, nibindi).

Ingaruka ya animasiyo yibi bice biterwa prefers-reduced-motionnibibazo byitangazamakuru. Reba igice cyagabanijwe cyicyiciro cyibisobanuro byacu .

Nyamuneka umenye ko karuseli yatewe idashyigikiwe, kandi karuseli muri rusange ntabwo yujuje ubuziranenge bwo kugerwaho.

Ubwanyuma, niba wubaka JavaScript yacu kuva isoko, birasabautil.js .

Urugero

Carousels ntabwo ihita isanzwe ibipimo bya slide. Nkibyo, urashobora gukenera gukoresha ibikorwa byingirakamaro cyangwa uburyo bwihariye kugirango ubone ubunini bukwiye. Mugihe karuseli ishyigikira ibyabanje / ubutaha kugenzura n'ibipimo, ntabwo bisabwa neza. Ongeraho kandi uhindure uko ubishaka.

Icyiciro .activegikeneye kongerwaho kamwe mumashusho ubundi karuseli ntizagaragara. Wemeze kandi gushiraho umwihariko idkuri .carouselkugenzura kubushake, cyane cyane niba ukoresha karuseli nyinshi kurupapuro rumwe. Kugenzura no kwerekana ibipimo bigomba kugira data-targetikiranga (cyangwa hrefkubihuza) bihuye idnibintu .carousel.

Igice gusa

Hano karuseli ifite amashusho gusa. Reba ahari ibishusho bya .d-blockkaruseli .w-100kugirango wirinde gushakisha amashusho adasanzwe.

Uburyo

Uburyo butajegajega ninzibacyuho

Inzira zose za API ntizihuza kandi zitangira inzibacyuho . Basubira kumuhamagara mugihe inzibacyuho itangiye ariko itararangira . Mubyongeyeho, uburyo bwo guhamagarira ibice byinzibacyuho bizirengagizwa .

Reba inyandiko zacu za JavaScript kubindi bisobanuro .

`.carousel(options)`

Itangiza karuseli hamwe nuburyo bwo guhitamo objecthanyuma igatangira gusiganwa ku magare binyuze mubintu.

$('.carousel').carousel({

Ibyabaye

Bootstrap ya karuseli yerekana ibintu bibiri byo guhuza imikorere ya karuseli. Ibyabaye byombi bifite imitungo yinyongera ikurikira:
