Karusel

Slayd-shou komponenti, masalan, karusel kabi elementlar, tasvirlar yoki matn slaydlari bo'ylab aylanish.

Ushbu sahifada

U qanday ishlaydi

Karusel - bu CSS 3D o'zgarishlari va biroz JavaScript-dan foydalangan holda yaratilgan bir qator kontentlar bo'ylab harakatlanish uchun slayd-shou. U bir qator rasmlar, matn yoki maxsus belgilar bilan ishlaydi. Shuningdek, u oldingi/keyingi boshqaruv va ko'rsatkichlarni qo'llab-quvvatlashni o'z ichiga oladi.

Page Visibility API qo'llab-quvvatlanadigan brauzerlarda veb-sahifa foydalanuvchiga ko'rinmasa (masalan, brauzer yorlig'i faol bo'lmaganda, brauzer oynasi kichraytirilganda va hokazo) karusel sirpanishdan saqlaydi.

Ushbu komponentning animatsiya effekti prefers-reduced-motionmedia so'roviga bog'liq. Maxsus imkoniyatlar hujjatlarimizning qisqartirilgan harakat bo'limiga qarang .

Iltimos, shuni yodda tutingki, ichki o'rnatilgan karusellar qo'llab-quvvatlanmaydi va karusellar odatda mavjudlik standartlariga mos kelmaydi.

Misol

Karusellar slayd o'lchamlarini avtomatik ravishda normallashtirmaydi. Shunday qilib, kontentni mos ravishda o'lchash uchun qo'shimcha yordam dasturlari yoki maxsus uslublardan foydalanishingiz kerak bo'lishi mumkin. Karusellar oldingi/keyingi boshqaruv va ko'rsatkichlarni qo'llab-quvvatlasa-da, ular aniq talab qilinmaydi. O'zingizga mos keladigan tarzda qo'shing va sozlang.

Sinfni .activeslaydlardan biriga qo'shish kerak, aks holda karusel ko'rinmaydi. idBundan tashqari, ixtiyoriy boshqaruv elementlari uchun noyobni o'rnatganingizga ishonch hosil .carouselqiling, ayniqsa bitta sahifada bir nechta karuseldan foydalansangiz. Boshqaruv va ko'rsatkich elementlari elementga mos keladigan atributga data-bs-target(yoki hrefhavolalar uchun) ega bo'lishi kerak .id.carousel

Faqat slaydlar

Bu yerda faqat slaydlar bilan karusel. Brauzerda standart tasvirni hizalanishini oldini olish uchun karusel tasvirlarining .d-blockmavjudligiga e'tibor bering ..w-100

Boshqaruv bilan

Oldingi va keyingi boshqaruv elementlarini qo'shish. Elementlardan foydalanishni tavsiya qilamiz <button>, lekin siz <a>bilan elementlardan ham foydalanishingiz mumkin role="button".

<div id="carouselExampleControls" class="carousel slide" data-bs-ride="carousel">

Ko'rsatkichlar bilan

Bundan tashqari, karuselga boshqaruv elementlari bilan bir qatorda ko'rsatkichlarni ham qo'shishingiz mumkin.

Sarlavhalar bilan

.carousel-captionHar qanday element ichidagi element bilan slaydlaringizga osongina sarlavha qo'shing .carousel-item. Ular quyida ko'rsatilganidek, ixtiyoriy displey yordam dasturlari bilan kichikroq ko'rish oynalarida osongina yashirilishi mumkin . Biz ularni dastlab bilan yashiramiz .d-noneva o'rta o'lchamdagi qurilmalarga qaytaramiz .d-md-block.

Foydalanish

Ma'lumotlar atributlari orqali

Karusel o'rnini osongina boshqarish uchun ma'lumotlar atributlaridan foydalaning. yoki data-bs-slidekalit so'zlarini qabul qiladi , bu esa slaydni joriy holatiga nisbatan o'zgartiradi. Shu bilan bir qatorda, slayd o'rnini bilan boshlangan ma'lum bir indeksga o'tkazadigan karuselga xom slayd indeksini o'tkazish uchun foydalaning .prevnextdata-bs-slide-todata-bs-slide-to="2"0

data-bs-ride="carousel"Atribut karuselni sahifa yuklanishidan boshlab animatsiya sifatida belgilash uchun ishlatiladi . Agar siz data-bs-ride="carousel"karuselni ishga tushirish uchun foydalanmasangiz, uni o'zingiz ishga tushirishingiz kerak. Uni bir xil karuselning aniq JavaScript ishga tushirishi (ortiqcha va keraksiz) bilan birgalikda ishlatib bo'lmaydi.

JavaScript orqali

Karuselga qo'lda qo'ng'iroq qiling:

var myCarousel = document.querySelector('#myCarousel')
var carousel = new bootstrap.Carousel(myCarousel)

Variantlar

Variantlar ma'lumotlar atributlari yoki JavaScript orqali uzatilishi mumkin. Maʼlumotlar atributlari uchun opsiya nomini quyidagi data-bs-kabi qoʻshing data-bs-interval="".

Ism Turi Standart Tavsif
interval raqam 5000 Ob'ektni avtomatik aylantirish o'rtasidagi kechikish vaqti. Agar bo'lsa false, karusel avtomatik ravishda aylanmaydi.
keyboard mantiqiy true Karusel klaviatura hodisalariga munosabat bildirishi kerakmi.
pause string | mantiqiy 'hover'

ga o'rnatilgan bo'lsa 'hover', karuselning aylanishini to'xtatib turadi va karuselning mouseenteraylanishini davom ettiradi mouseleave. Agar ga oʻrnatilgan boʻlsa false, kursorni karusel ustiga olib borish uni toʻxtatib qoʻymaydi.

Sensorli qurilmalarda, ga o‘rnatilgan bo‘lsa 'hover', velosipedda harakatlanish avtomatik ravishda davom etishdan oldin ikki oraliq uchun to‘xtatiladi touchend(foydalanuvchi karusel bilan aloqani tugatgandan so‘ng). E'tibor bering, bu sichqonchaning yuqoridagi xatti-harakatlariga qo'shimcha.
ride string | mantiqiy false Foydalanuvchi birinchi elementni qo'lda aylantirgandan so'ng, karuselni avtomatik ijro etadi. ga oʻrnatilgan boʻlsa 'carousel', yuklanganda karuselni avtomatik oʻynaydi.
wrap mantiqiy true Karusel doimiy ravishda aylanishi kerakmi yoki qattiq to'xtashlari kerakmi.
touch mantiqiy true Karusel sensorli ekranli qurilmalarda chap/o‘ngga surish harakatlarini qo‘llab-quvvatlashi kerakmi.

Usullari

Asinxron usullar va o'tishlar

Barcha API usullari asenkron va o'tishni boshlaydi . O'tish boshlanishi bilanoq, lekin tugashidan oldin ular qo'ng'iroq qiluvchiga qaytadilar . Bundan tashqari, o'tish komponentidagi usul chaqiruvi e'tiborga olinmaydi .

Qo'shimcha ma'lumot olish uchun bizning JavaScript hujjatlariga qarang .

Siz karusel konstruktori yordamida karusel misolini yaratishingiz mumkin, masalan, qo'shimcha opsiyalarni ishga tushirish va elementlar bo'ylab aylanishni boshlash:

var myCarousel = document.querySelector('#myCarousel')
var carousel = new bootstrap.Carousel(myCarousel, {
  interval: 2000,
  wrap: false
})

dispose Elementning karuselini yo'q qiladi. (DOM elementida saqlangan ma'lumotlarni o'chiradi)
getInstance DOM elementi bilan bog'langan karusel misolini olish imkonini beruvchi statik usul, uni quyidagicha ishlatishingiz mumkin:bootstrap.Carousel.getInstance(element)
getOrCreateInstance DOM elementiga bog'langan karusel misolini qaytaradigan yoki ishga tushirilmagan bo'lsa, yangisini yaratadigan statik usul. Siz undan shunday foydalanishingiz mumkin:bootstrap.Carousel.getOrCreateInstance(element)

Voqealar

Bootstrap-ning karusel klassi karusel funksiyasiga ulanish uchun ikkita hodisani ochib beradi. Ikkala hodisa ham quyidagi qo'shimcha xususiyatlarga ega:

  • direction: Karusel siljish yo'nalishi (yoki "left"yoki "right").
  • relatedTarget: Faol element sifatida joyiga surilayotgan DOM elementi.
  • from: Joriy element indeksi
  • to: Keyingi element indeksi

Barcha karusel hodisalari karuselning o'ziga (ya'ni <div class="carousel">) qaratiladi.
