ອົງປະກອບສະໄລ້ໂຊສຳລັບການຖີບລົດຜ່ານອົງປະກອບ-ຮູບພາບ ຫຼືສະໄລ້ຂອງຂໍ້ຄວາມ-ເຊັ່ນ: carousel.

ໃນໜ້ານີ້

ມັນເຮັດວຽກແນວໃດ

carousel ແມ່ນ slideshow ສໍາລັບການຂີ່ລົດຖີບຜ່ານຊຸດຂອງເນື້ອຫາ, ສ້າງດ້ວຍ CSS 3D transforms ແລະເລັກນ້ອຍຂອງ JavaScript. ມັນເຮັດວຽກກັບຊຸດຮູບພາບ, ຂໍ້ຄວາມ, ຫຼືເຄື່ອງໝາຍທີ່ກຳນົດເອງ. ມັນຍັງປະກອບມີການສະຫນັບສະຫນູນສໍາລັບການຄວບຄຸມທີ່ຜ່ານມາ / ຕໍ່ໄປແລະຕົວຊີ້ວັດ.

ໃນຕົວທ່ອງເວັບທີ່ Page Visibility API ຮອງຮັບ, carousel ຈະຫຼີກລ່ຽງການເລື່ອນເມື່ອຫນ້າເວັບບໍ່ເຫັນກັບຜູ້ໃຊ້ (ເຊັ່ນ: ເມື່ອແຖບຕົວທ່ອງເວັບບໍ່ເຄື່ອນໄຫວ, ປ່ອງຢ້ຽມຂອງຕົວທ່ອງເວັບຖືກຫຼຸດລົງ, ແລະອື່ນໆ).

ຜົນກະທົບຂອງພາບເຄື່ອນໄຫວຂອງອົງປະກອບນີ້ແມ່ນຂຶ້ນກັບການ prefers-reduced-motionສອບຖາມສື່. ເບິ່ງ ພາກສ່ວນການເຄື່ອນໄຫວທີ່ຫຼຸດລົງຂອງເອກະສານການຊ່ວຍເຂົ້າເຖິງຂອງພວກເຮົາ .

ກະລຸນາຮັບຊາບວ່າ carousels ຊ້ອນກັນບໍ່ໄດ້ຮັບການສະຫນັບສະຫນູນ, ແລະ carousels ໂດຍທົ່ວໄປແມ່ນບໍ່ປະຕິບັດຕາມມາດຕະຖານການເຂົ້າເຖິງ.

Methods

Asynchronous methods and transitions

All API methods are asynchronous and start a transition. They return to the caller as soon as the transition is started but before it ends. In addition, a method call on a transitioning component will be ignored.

See our JavaScript documentation for more information.

You can create a carousel instance with the carousel constructor, for example, to initialize with additional options and start cycling through items:

var myCarousel = document.querySelector('#myCarousel')
var carousel = new bootstrap.Carousel(myCarousel, {
  interval: 2000,
  wrap: false
})
Method Description
cycle Cycles through the carousel items from left to right.
pause Stops the carousel from cycling through items.
prev Cycles to the previous item. Returns to the caller before the previous item has been shown (e.g., before the slid.bs.carousel event occurs).
next Cycles to the next item. Returns to the caller before the next item has been shown (e.g., before the slid.bs.carousel event occurs).
nextWhenVisible Don't cycle carousel to next when the page isn't visible or the carousel or its parent isn't visible. Returns to the caller before the target item has been shown
to Cycles the carousel to a particular frame (0 based, similar to an array). Returns to the caller before the target item has been shown (e.g., before the slid.bs.carousel event occurs).
dispose Destroys an element's carousel. (Removes stored data on the DOM element)
getInstance Static method which allows you to get the carousel instance associated to a DOM element, you can use it like this: bootstrap.Carousel.getInstance(element)
getOrCreateInstance Static method which returns a carousel instance associated to a DOM element or create a new one in case it wasn't initialized. You can use it like this: bootstrap.Carousel.getOrCreateInstance(element)

Events

Bootstrap’s carousel class exposes two events for hooking into carousel functionality. Both events have the following additional properties:

  • direction: The direction in which the carousel is sliding (either "left" or "right").
  • relatedTarget: The DOM element that is being slid into place as the active item.
  • from: The index of the current item
  • to: The index of the next item

All carousel events are fired at the carousel itself (i.e. at the <div class="carousel">).

Event type Description
slide.bs.carousel Fires immediately when the slide instance method is invoked.
slid.bs.carousel Fired when the carousel has completed its slide transition. 
var myCarousel = document.getElementById('myCarousel')

myCarousel.addEventListener('slide.bs.carousel', function () {
  // do something...
})
