I-Carousel

Ingxenye yombukiso wesilayidi yokuhamba ngebhayisikili ezintweni—izithombe noma amaslayidi ombhalo—njenge-carousel.

Kuleli khasi

Isebenza kanjani

I-carousel iwumbukiso wesilayidi sokuhamba ngebhayisikili ngochungechunge lokuqukethwe, olwakhiwe ngezinguquko ze-CSS 3D kanye ne-JavaScript encane. Isebenza ngochungechunge lwezithombe, umbhalo, noma imakhaphu yangokwezifiso. Kuhlanganisa futhi nokusekelwa kwezilawuli zangaphambilini/ezilandelayo nezinkomba.

Ezipheqululini lapho i- Page Visibility API isekelwa khona, i-carousel izogwema ukuslayida lapho ikhasi lewebhu lingabonakali kumsebenzisi (njengalapho ithebhu yesiphequluli ingasebenzi, iwindi lesiphequluli lincishiswa, njll.).

Umthelela wokugqwayiza wale ngxenye uncike prefers-reduced-motionembuzweni wemidiya. Bona ingxenye yokunyakaza encishisiwe yemibhalo yethu yokufinyeleleka .

Sicela uqaphele ukuthi ama-carousel afakwe esidlekeni awasekelwe, futhi ama-carousels ngokuvamile awahambisani nezindinganiso zokufinyeleleka.

Isibonelo

Ama-carousels awazimisi ngokuzenzakalelayo ubukhulu besilayidi. Kanjalo, ungase udinge ukusebenzisa izinsiza ezengeziwe noma izitayela zangokwezifiso ukuze usayizi ofanele wokuqukethwe. Nakuba ama-carousels esekela izilawuli zangaphambilini/ezilandelayo nezinkomba, azidingeki ngokusobala. Engeza futhi wenze ngokwezifiso njengoba ubona kufanelekile.

Ikilasi .activelidinga ukwengezwa kwesinye sezilayidi ngaphandle kwalokho i-carousel ngeke ibonakale. Futhi qiniseka ukuthi usetha okuhlukile idkuzilawuli .carouselozikhethela, ikakhulukazi uma usebenzisa ama-carousel amaningi ekhasini elilodwa. Izinto zokulawula nezinkomba kufanele zibe data-bs-targetnesibaluli (noma sezixhumanisi href) esifana nesici.id.carousel

Amaslayidi kuphela

Nali i-carousel enamaslayidi kuphela. Qaphela ukuba khona kwezithombe .d-blockkanye .w-100naku-carousel ukuze uvimbele ukuqondanisa okuzenzakalelayo kwesiphequluli.

Ngezilawuli

Yengeza kuzilawuli zangaphambilini nezilandelayo. Sincoma ukusebenzisa ama <button>-elementi, kodwa ungasebenzisa ama- <a>elementi ane- role="button".

Ngamagama-ncazo

Engeza amagama-ncazo kumaslayidi akho kalula nge- .carousel-captionelementi ngaphakathi kwanoma iyiphi .carousel-item. Angafihlwa kalula ezindaweni zokubuka ezincane, njengoba kuboniswe ngezansi, ngezinsiza zokubonisa ozikhethela . Sizifihla ekuqaleni .d-nonefuthi sizibuyisele kumadivayisi anosayizi omaphakathi ane- .d-md-block.

I-Crossfade

Engeza .carousel-fadeku-carousel yakho ukuze uphilise amaslayidi ngoshintsho olufiphele esikhundleni sesilayidi. Ngokuya ngokuqukethwe kwe-carousel yakho (isb, umbhalo wamaslayidi kuphela), ungase ufune ukwengeza .bg-bodynoma i-CSS yangokwezifiso ku- .carousel-items ukuze unqamule kahle.

Khubaza ukuswayipha kokuthinta

Ama-carousels asekela ukuswayiphela kwesokunxele/kwesokudla kumadivayisi esikrini esithintwayo ukuze ahambe phakathi kwamaslayidi. Lokhu kungakhutshazwa kusetshenziswa data-bs-touchisibaluli. Isibonelo esingezansi futhi asifaki data-bs-rideisibaluli ngakho-ke asidlali ngokuzenzakalela.

Inguquko yangokwezifiso

Ubude besikhathi soshintsho .carousel-itemlungashintshwa ngokuhluka kwe- $carousel-transition-durationSass ngaphambi kokuhlanganiswa noma izitayela zangokwezifiso uma usebenzisa i-CSS ehlanganisiwe. Uma kwenziwa izinguquko eziningi, qiniseka ukuthi uguquko luchazwa kuqala (isb transition: transform 2s ease, opacity .5s ease-out.).

Sass

Okuguquguqukayo

Okuguquguqukayo kwawo wonke ama-carousel:

Ukusetshenziswa

Ngezibaluli zedatha

Sebenzisa izibaluli zedatha ukuze ulawule kalula ukuma kwe-carousel. data-bs-slideyamukela amagama angukhiye prevnoma next, eshintsha indawo yesilayidi ngokuhlobene nendawo yaso yamanje. Kungenjalo, sebenzisa data-bs-slide-toukudlulisa inkomba yesilayidi eluhlaza ku-carousel data-bs-slide-to="2", eshintsha indawo yesilayidi ibe inkomba ethile eqala ngo- 0.

Isibaluli data-bs-ride="carousel"sisetshenziselwa ukumaka i-carousel njengokugqwayiza kusukela ekulayishweni kwekhasi. Uma ungasebenzisi data-bs-ride="carousel"ukuqalisa i-carousel yakho, kufanele uyiqalise ngokwakho. Ngeke isetshenziswe kuhlanganiswe (nokungadingeki nokungadingeki) ukuqaliswa okucacile kwe-JavaScript kwe-carousel efanayo.

Nge-JavaScript

Shayela i-carousel ngokwenza:

const carousel = new bootstrap.Carousel('#myCarousel')

Izinketho

Njengoba izinketho zingadluliswa ngezibaluli zedatha noma i-JavaScript, ungakwazi ukwengeza igama lenketho kokuthi data-bs-, njengaku data-bs-animation="{value}". Qiniseka ukuthi ushintsha uhlobo lwekesi legama lenketho lisuka ku- “ camelCase ” liye ku- “ kebab-case ” lapho udlulisa izinketho ngezibaluli zedatha. Isibonelo, sebenzisa data-bs-custom-class="beautifier"esikhundleni se- data-bs-customClass="beautifier".

Kusukela ku-Bootstrap 5.2.0, zonke izingxenye zisekela isibaluli sedatha egodliwe esihlolwayodata-bs-config esingafaka ukucushwa kwengxenye elula njengochungechunge lwe-JSON. Uma into inezibaluli , inani lokugcina lizoba data-bs-config='{"delay":0, "title":123}'futhi izibaluli zedatha ezihlukene zizokhipha amanani anikezwe ngomhla ka- . Ngaphezu kwalokho, izibaluli zedatha ezikhona ziyakwazi ukubeka amanani e-JSON afana .data-bs-title="456"title456data-bs-configdata-bs-delay='{"show":0,"hide":150}'

Igama Uhlobo Okuzenzakalelayo Incazelo
interval inombolo 5000 Inani lesikhathi sokubambezeleka phakathi kokuhamba ngebhayisikili ngokuzenzakalela into.
keyboard boolean true Ukuthi i-carousel kufanele sisabele emicimbini yekhibhodi.
pause string, boolean "hover" Uma kusethelwe ku- "hover", imisa isikhashana ukuhamba ngebhayisikili kwe-carousel mouseenterbese iqalisa kabusha ukugijima kwe-carousel kuvuliwe mouseleave. Uma kusethelwe ku- false, ukuhambisa phezulu kwe-carousel ngeke kuyimise isikhashana. Kumadivayisi anikwe amandla ukuthinta, uma kusethelwe ku- "hover", ukuhamba ngebhayisikili kuzoma touchend(uma umsebenzisi eseqedile ukusebenzisana ne-carousel) izikhawu ezimbili, ngaphambi kokuthi kuqalise kabusha ngokuzenzakalelayo. Lokhu kungaphezu kokuziphatha kwegundane.
ride string, boolean false Uma kusethelwe ku- true, idlala ngokuzenzakalela i-carousel ngemva kokuba umsebenzisi ejikelezise mathupha into yokuqala. Uma kusethelwe ku- "carousel", idlala ngokuzenzakalela i-carousel elayishiwe.
touch boolean true Ukuthi i-carousel kufanele isekele ukusebenzisana kokuswayipha kwesokunxele/kwesokudla kumadivayisi wesikrini esithintwayo.
wrap boolean true Ukuthi i-carousel kufanele ijikeleze ngokuqhubekayo noma ibe nokuma kanzima.

Izindlela

Izindlela ze-Asynchronous kanye noshintsho

Zonke izindlela ze-API azivumelanisi futhi ziqala inguquko . Babuyele kofonayo uma sekuqalwa uguquko kodwa lungakapheli . Ngokungeziwe, ikholi yendlela engxenyeni yoshintsho izozitshwa .

Bheka imibhalo yethu ye-JavaScript ukuze uthole ulwazi olwengeziwe .

Ungakha isenzakalo se-carousel nomakhi we-carousel, isibonelo, ukuze uqalise ngezinketho ezengeziwe futhi uqale ukuhamba ngebhayisikili ngokusebenzisa izinto:

const myCarouselElement = document.querySelector('#myCarousel')
const carousel = new bootstrap.Carousel(myCarouselElement, {
  interval: 2000,
  wrap: false
})
Indlela Incazelo
cycle Izungeza izinto ze-carousel ukusuka kwesokunxele kuye kwesokudla.
dispose Icekela phansi i-carousel yento. (Isusa idatha egciniwe kusici se-DOM)
getInstance Indlela emile ekuvumela ukuthi uthole isibonelo se-carousel esihlotshaniswa nento ye-DOM, ungayisebenzisa kanje: bootstrap.Carousel.getInstance(element).
getOrCreateInstance Indlela emile ebuyisela isenzakalo se-carousel esihlotshaniswa nento ye-DOM noma idale entsha uma kwenzeka ingaqaliswanga. Ungayisebenzisa kanje bootstrap.Carousel.getOrCreateInstance(element):.
next Imijikelezo eya entweni elandelayo. Ibuyela kofonayo ngaphambi kokuba kuboniswe into elandelayo (isb, ngaphambi kokuba slid.bs.carouselkwenzeke umcimbi).
nextWhenVisible Ungajikelezi i-carousel uye kwelinye lapho ikhasi lingabonakali noma i-carousel noma umzali wayo engabonakali. Ibuyela kofonayo ngaphambi kokuthi kuboniswe into eqondiwe .
pause Imisa i-carousel ekuhambeni ngebhayisikili ezintweni.
prev Imijikelezo eya entweni edlule. Ibuyela kofonayo ngaphambi kokuba kuboniswe into yangaphambilini (isb, ngaphambi kokuba slid.bs.carouselkwenzeke umcimbi).
to Ibiyela i-carousel kuhlaka oluthile (okusekelwe ngo-0, okufana namalungu afanayo). Ibuyela koshaya ucingo ngaphambi kokuba kuboniswe into eqondiwe (isb, ngaphambi kokuba slid.bs.carouselkwenzeke umcimbi).

Imicimbi

Ikilasi le-carousel le-Bootstrap lidalula imicimbi emibili yokuxhunywa ekusebenzeni kwe-carousel. Yomibili imicimbi inezimpawu ezengeziwe ezilandelayo:

  • direction: Isiqondiso lapho i-carousel ishelela khona ( "left"noma "right").
  • relatedTarget: I-elementi ye-DOM eslayishwa endaweni njengento esebenzayo.
  • from: Inkomba yento yamanje
  • to: Inkomba yento elandelayo

Yonke imicimbi ye-carousel idutshulwa ku-carousel ngokwayo (okungukuthi ku- <div class="carousel">).
