I-Carousel

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

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.

Okokugcina, uma wakha i-JavaScript yethu ngomthombo, kudingautil.js .

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-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.

<div id="carouselExampleSlidesOnly" class="carousel slide" data-ride="carousel">
  <div class="carousel-inner">
    <div class="carousel-item active">
        <img src="..." class="d-block w-100" alt="...">

    </div>
  </div>
</div>

Ngezilawuli

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

<div id="carouselExampleControls" class="carousel slide" data-ride="carousel">
  <div class="carousel-inner">
    <div class="carousel-item active">

 <button class="carousel-control-prev" type="button" data-target="#carouselExampleControls" data-slide="prev">
    <span class="carousel-control-prev-icon" aria-hidden="true"></span>
    <span class="sr-only">Previous</span>
  </button>
  <button class="carousel-control-next" type="button" data-target="#carouselExampleControls" data-slide="next">
    <span class="carousel-control-next-icon" aria-hidden="true"></span>
    <span class="sr-only">Next</span>
  </button>
</div>

Ngezinkomba

Ungakwazi futhi ukwengeza izinkomba ku-carousel, eduze nezilawuli, futhi.

<div id="carouselExampleIndicators" class="carousel slide" data-ride="carousel">
  <ol class="carousel-indicators">
    <li data-target="#carouselExampleIndicators" data-slide-to="0" class="active"></li>
    <li data-target="#carouselExampleIndicators" data-slide-to="1"></li>
    <li data-target="#carouselExampleIndicators" data-slide-to="2"></li>
  </ol>
  <div class="carousel-inner">

    <span class="carousel-control-next-icon" aria-hidden="true"></span>
    <span class="sr-only">Next</span>
  </button>
</div>

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.

Ilebula yesilayidi sokuqala

Okunye okuqukethwe kwesimeli kwesilayidi sokuqala.

Ilebula yesilayidi sesibili

Okunye okuqukethwe kwesimeli esimele isilayidi sesibili.

Ilebula yesilayidi yesithathu

Okunye okuqukethwe kwesimeli esimele isilayidi sesithathu.

</div>

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.

<div id="carouselExampleFade" class="carousel slide carousel-fade" data-ride="carousel">
  <div class="carousel-inner">
    <div class="carousel-item active">
      <img src="..." class="d-block w-100" alt="...">

    <span class="sr-only">Next</span>
  </button>
</div>

`.carousel-item`Isikhawu somuntu ngamunye

Engeza data-interval=""ku-a .carousel-itemukuze ushintshe inani lesikhathi sokulibaziseka phakathi kokuhamba ngebhayisikili ngokuzenzakalelayo ukuya entweni elandelayo.

<div id="carouselExampleInterval" class="carousel slide" data-ride="carousel">
  <div class="carousel-inner">
    <div class="carousel-item active" data-interval="10000">
      <img src="..." class="d-block w-100" alt="...">

Khubaza ukuswayipha kokuthinta

Ama-carousels asekela ukuswayiphela kwesokunxele/kwesokudla kumadivayisi esikrini esithintwayo ukuze ahambe phakathi kwamaslayidi. Lokhu kungakhutshazwa kusetshenziswa data-touchisibaluli. Isibonelo esingezansi naso asibandakanyi data-rideisibaluli futhi data-interval="false"sinaso asidlali ngokuzenzakalela.

<div id="carouselExampleControlsNoTouching" class="carousel slide" data-touch="false" data-interval="false">
  <div class="carousel-inner">
    <div class="carousel-item active">
      <img src="..." class="d-block w-100" alt="...">
    </div>

      <img src="..." class="d-block w-100" alt="...">
    </div>
    <div class="carousel-item">
      <img src="..." class="d-block w-100" alt="...">
    </div>
  </div>
  <button class="carousel-control-prev" type="button" data-target="#carouselExampleControlsNoTouching" data-slide="prev">
    <span class="carousel-control-prev-icon" aria-hidden="true"></span>
    <span class="sr-only">Previous</span>
  </button>
  <button class="carousel-control-next" type="button" data-target="#carouselExampleControlsNoTouching" data-slide="next">
    <span class="carousel-control-next-icon" aria-hidden="true"></span>
    <span class="sr-only">Next</span>
  </button>
</div>

Ukusetshenziswa

Ngezibaluli zedatha

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

Isibaluli data-ride="carousel"sisetshenziselwa ukumaka i-carousel njengokugqwayiza kusukela ekulayishweni kwekhasi. Uma ungasebenzisi data-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:

$('.carousel').carousel()

Izinketho

Izinketho zingadluliswa ngezibaluli zedatha noma i-JavaScript. Ukuze uthole izibaluli zedatha, faka igama lenketho kokuthi data-, njengaku data-interval="".

Igama	Uhlobo	Okuzenzakalelayo	Incazelo
isikhawu	inombolo	5000	Inani lesikhathi sokubambezeleka phakathi kokuhamba ngebhayisikili ngokuzenzakalelayo into. Uma `false`, i-carousel ngeke ijikeleze ngokuzenzakalelayo.
ikhibhodi	boolean	iqiniso	Ukuthi i-carousel kufanele sisabele emicimbini yekhibhodi.
ima kancane	umucu \| boolean	'hambahamba'	Uma kusethelwe ku- `'hover'`, imisa isikhashana ukuhamba ngebhayisikili kwe-carousel `mouseenter`bese 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. Qaphela ukuthi lokhu kungaphezu kokuziphatha kwegundane okungenhla.
gibela	umucu	amanga	Idlala ngokuzenzakalela i-carousel ngemuva kokuthi umsebenzisi ajikelezise mathupha into yokuqala. Uma kusethelwe ku- `'carousel'`, idlala ngokuzenzakalela i-carousel elayishiwe.
ukugoqa	boolean	iqiniso	Ukuthi i-carousel kufanele ijikeleze ngokuqhubekayo noma ibe nokuma kanzima.
ukuthinta	boolean	iqiniso	Ukuthi i-carousel kufanele isekele ukusebenzisana kokuswayipha kwesokunxele/kwesokudla kumadivayisi wesikrini esithintwayo.

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 .

`.carousel(options)`

Iqalisa i-carousel ngezinketho zokuzithandela objectfuthi iqala ukuhamba ngebhayisikili ezintweni.

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

`.carousel('cycle')`

Izungeza izinto ze-carousel ukusuka kwesokunxele kuye kwesokudla.

`.carousel('pause')`

Imisa i-carousel ekuhambeni ngebhayisikili ezintweni.

`.carousel(number)`

Ibiyela i-carousel kuhlaka oluthile (okusekelwe ngo-0, okufana namalungu afanayo). Ibuyela kofonayo ngaphambi kokuba kuboniswe into eqondiwe (okungukuthi ngaphambi kokuba slid.bs.carouselumcimbi wenzeke).

`.carousel('prev')`

Imijikelezo eya entweni edlule. Ibuyela kofonayo ngaphambi kokuba kuboniswe into yangaphambilini (okungukuthi ngaphambi kokuba slid.bs.carouselkwenzeke umcimbi).

`.carousel('next')`

Imijikelezo eya entweni elandelayo. Ibuyela kofonayo ngaphambi kokuba kuboniswe into elandelayo (okungukuthi ngaphambi kokuba slid.bs.carouselkwenzeke umcimbi).

`.carousel('dispose')`

Icekela phansi i-carousel yento.

`.carousel('nextWhenVisible')`

Ungajikelezi i-carousel uye kwelinye lapho ikhasi lingabonakali noma i-carousel noma umzali wayo engabonakali. Ibuyela kofonayo ngaphambi kokuba kuboniswe into elandelayo (okungukuthi ngaphambi kokuba slid.bs.carouselkwenzeke umcimbi).

`.carousel('to')`

Ibiyela i-carousel kuhlaka oluthile (okusekelwe ngo-0, okufana namalungu afanayo). Ibuyela kofonayo ngaphambi kokuba kuboniswe into elandelayo (okungukuthi 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">).

Uhlobo Lomcimbi	Incazelo
slide.bs.carousel	Lo mcimbi uvutha ngokushesha lapho `slide`indlela yesibonelo isetshenziswa.
slid.bs.carousel	Lo mcimbi uxoshwa lapho i-carousel isiqedile ukuguqulwa kwama-slide.

$('#myCarousel').on('slide.bs.carousel', function () {
  // do something...
})

Shintsha ubude besikhathi soshintsho

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