Modal

Saytingizga yorug'lik qutilari, foydalanuvchi bildirishnomalari yoki butunlay moslashtirilgan kontent uchun dialog oynalarini qo'shish uchun Bootstrap's JavaScript modal plaginidan foydalaning.

Ushbu sahifada

U qanday ishlaydi

Bootstrap-ning modal komponentidan foydalanishni boshlashdan oldin, quyidagini o'qib chiqing, chunki bizning menyu variantlarimiz yaqinda o'zgargan.

Modallar HTML, CSS va JavaScript bilan yaratilgan. Ular hujjatdagi hamma narsaning ustiga joylashtiriladi va <body>modal tarkib o'rniga aylantirish uchun aylantirishni olib tashlang.
Modal "fon" ustiga bosish avtomatik ravishda modalni yopadi.
Bootstrap bir vaqtning o'zida faqat bitta modal oynani qo'llab-quvvatlaydi. Ichki modallar qo‘llab-quvvatlanmaydi, chunki ular foydalanuvchi tajribasini yomon deb hisoblaymiz.
Modallar dan foydalanadi position: fixed, bu ba'zan uning ko'rsatilishida biroz o'ziga xos bo'lishi mumkin. Iloji bo'lsa, boshqa elementlarning potentsial shovqinlarini oldini olish uchun modal HTML-ni yuqori darajali joyga qo'ying. .modalBoshqa sobit element ichiga joylashtirishda muammolarga duch kelishingiz mumkin.
Yana bir bor, tufayli position: fixedmobil qurilmalarda modallardan foydalanishda ba'zi ogohlantirishlar mavjud. Tafsilotlar uchun brauzerimizni qoʻllab-quvvatlash boʻlimiga qarang .
HTML5 o'z semantikasini qanday aniqlaganligi sababli , autofocusHTML atributi Bootstrap modallarida hech qanday ta'sir ko'rsatmaydi. Xuddi shu effektga erishish uchun ba'zi maxsus JavaScript-dan foydalaning:

var myModal = document.getElementById('myModal')
var myInput = document.getElementById('myInput')

myModal.addEventListener('shown.bs.modal', function () {
  myInput.focus()
})

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

Namoyishlar va foydalanish ko'rsatmalarini o'qishni davom eting.

Misollar

Quyida statik modal misol keltirilgan (uning positionva displaybekor qilingan degan ma'noni anglatadi). Modal sarlavha, modal tanasi ( uchun talab qilinadi padding) va modal altbilgi (ixtiyoriy) kiradi. Iloji bo'lsa, rad etish amallari bilan modal sarlavhalarni kiritishingizni yoki boshqa ochiq-oydin rad etish amalini taqdim etishingizni so'raymiz.

Uzun kontentni aylantirish

Modallar foydalanuvchining ko'rish oynasi yoki qurilmasi uchun juda uzun bo'lsa, ular sahifaning o'zidan mustaqil ravishda aylanadi. Nima demoqchi ekanligimizni tushunish uchun quyidagi demoni sinab ko'ring.

.modal-dialog-scrollablega qo'shish orqali modal tanasini aylantirish imkonini beruvchi aylantiriladigan modal yaratishingiz mumkin .modal-dialog.

<!-- Scrollable modal -->

Maslahatlar va popoverlar

Maslahatlar va popoverlar kerak bo'lganda modallarga joylashtirilishi mumkin. Modallar yopilganda, ichidagi barcha maslahatlar va popoverlar ham avtomatik ravishda o'chiriladi.

<div class="modal-body">
  <h5>Popover in a modal</h5>

Modallar o'rtasida almashish

data-bs-targetva data-bs-toggleatributlarini oqilona joylashtirish bilan bir nechta modallar o'rtasida almashish . Misol uchun, parolni tiklash modalni allaqachon ochiq kirish modali ichidan almashtirishingiz mumkin. E'tibor bering, bir vaqtning o'zida bir nechta modallarni ochib bo'lmaydi - bu usul ikkita alohida modal o'rtasida almashinadi.

Birinchi modalni oching

Animatsiyani o'zgartirish

O'zgaruvchi modal fade-in animatsiyasidan oldin $modal-fade-transformning o'zgartirish holatini aniqlaydi, o'zgaruvchi modal fade-in animatsiyasi oxirida -ning transformatsiyasini aniqlaydi ..modal-dialog$modal-show-transform.modal-dialog

Masalan, kattalashtirish animatsiyasini xohlasangiz, o'rnatishingiz mumkin $modal-fade-transform: scale(.8).

Animatsiyani olib tashlang

Ko'rish uchun so'nish o'rniga oddiygina paydo bo'ladigan modallar uchun .fadesinfni modal belgilashingizdan olib tashlang.

<div class="modal" tabindex="-1" aria-labelledby="..." aria-hidden="true">

Dinamik balandliklar

Agar modal ochiq bo'lganda uning balandligi o'zgarsa, myModal.handleUpdate()aylantirish paneli paydo bo'lganda modal o'rnini qayta sozlash uchun qo'ng'iroq qilishingiz kerak.

Foydalanish imkoniyati

aria-labelledby="..."Modal sarlavhaga havola qilib, ga qo'shishni unutmang .modal. aria-describedbyBundan tashqari, siz on bilan modal dialogingizning tavsifini berishingiz mumkin .modal. E'tibor bering, siz qo'shishingiz shart emas, role="dialog"chunki biz uni allaqachon JavaScript orqali qo'shdik.

YouTube videolarini joylashtirish

YouTube videolarini modallarga joylashtirish, ijroni avtomatik ravishda to‘xtatish va boshqalar uchun Bootstrap-da bo‘lmagan qo‘shimcha JavaScript-ni talab qiladi. Qo'shimcha ma'lumot olish uchun ushbu foydali Stack Overflow postiga qarang.

Ixtiyoriy o'lchamlar

Modallar uchta ixtiyoriy o'lchamga ega bo'lib, ularni o'zgartirish sinflari orqali joylashtirish mumkin .modal-dialog. Ushbu o'lchamlar torroq ko'rish oynalarida gorizontal aylantirish panellarini oldini olish uchun ma'lum to'xtash nuqtalarida boshlanadi.

Hajmi	Sinf	Modal maksimal kenglik
Kichik	`.modal-sm`	`300px`
Standart	Yo'q	`500px`
Katta	`.modal-lg`	`800px`
Juda katta	`.modal-xl`	`1140px`

Modifikator sinfi bo'lmagan standart modalimiz "o'rta" o'lchamdagi modalni tashkil qiladi.

<div class="modal-dialog modal-xl">...</div>
<div class="modal-dialog modal-lg">...</div>
<div class="modal-dialog modal-sm">...</div>

Yana bir bekor qilish - bu foydalanuvchi ko'rish oynasini qamrab oluvchi modalni ochish variantidir, uni o'zgartirish sinflari orqali mavjud .modal-dialog.

Foydalanish

Modal plagin ma'lumotlar atributlari yoki JavaScript orqali so'ralganda yashirin tarkibingizni almashtiradi. Shuningdek, u standart aylantirish harakatini bekor qiladi va .modal-backdropmodal tashqarisida bosilganda ko'rsatilgan modallarni o'chirish uchun bosish maydonini ta'minlash uchun a hosil qiladi.

Ma'lumotlar atributlari orqali

Oʻchirish

JavaScript yozmasdan modalni faollashtiring. Oʻzgartirish uchun muayyan modalni nishonga olish uchun yoki data-bs-toggle="modal"tugmasi kabi boshqaruvchi elementga oʻrnating .data-bs-target="#foo"href="#foo"

<button type="button" data-bs-toggle="modal" data-bs-target="#myModal">Launch modal</button>

Rad etish

O'chirishni modal ichidagi tugmadagidata atribut yordamida quyida ko'rsatilgandek amalga oshirish mumkin:

<button type="button" class="btn-close" data-bs-dismiss="modal" aria-label="Close"></button>

yoki modal tashqarisidagi tugmani data-bs-targetquyida ko'rsatilgandek ishlating:

<button type="button" class="btn-close" data-bs-dismiss="modal" data-bs-target="#my-modal" aria-label="Close"></button>

Modalni o'chirishning ikkala usuli ham qo'llab-quvvatlansa-da, modalni tashqaridan o'chirish WAI-ARIA modal dialogining dizayn namunasiga mos kelmasligini yodda tuting . Buni o'zingizning xavf-xataringiz bilan qiling.

JavaScript orqali

JavaScript-ning bitta qatori bilan modal yarating:

var myModal = new bootstrap.Modal(document.getElementById('myModal'), options)

Variantlar

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

Ism	Turi	Standart	Tavsif
`backdrop`	mantiqiy yoki satr`'static'`	`true`	Modal fon elementini o'z ichiga oladi. Shu bilan bir qatorda, `static`bosilganda modalni yopmaydigan fon uchun belgilang.
`keyboard`	mantiqiy	`true`	Escape tugmasi bosilganda modalni yopadi
`focus`	mantiqiy	`true`	Boshlanganda fokusni modalga qo'yadi.

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 .

Bootstrap’s modal class exposes a few events for hooking into modal functionality. All modal events are fired at the modal itself (i.e. at the <div class="modal">).

`show.bs.modal`	This event fires immediately when the `show` instance method is called. If caused by a click, the clicked element is available as the `relatedTarget` property of the event.
`shown.bs.modal`	This event is fired when the modal has been made visible to the user (will wait for CSS transitions to complete). If caused by a click, the clicked element is available as the `relatedTarget` property of the event.
`hide.bs.modal`	This event is fired immediately when the `hide` instance method has been called.
`hidden.bs.modal`	This event is fired when the modal has finished being hidden from the user (will wait for CSS transitions to complete).
