Yordamchi texnologiyalarga ma'no etkazish

Ma'no qo'shish uchun rangdan foydalanish faqat vizual ko'rsatkichni ta'minlaydi, bu yordamchi texnologiyalar foydalanuvchilariga, masalan, ekranni o'qiydiganlarga etkazilmaydi. Rang bilan belgilangan ma'lumotlar mazmunning o'zidan (masalan, ko'rinadigan matn) aniq bo'lishiga yoki .sr-onlysinf bilan yashiringan qo'shimcha matn kabi muqobil vositalar orqali kiritilganligiga ishonch hosil qiling.

Yo'qotilmoqda

Ogohlantirish JavaScript plaginidan foydalanib, har qanday ogohlantirishni inline o'chirib qo'yish mumkin. Mana shunday:

  • Ogohlantirish plaginini yoki kompilyatsiya qilingan Bootstrap JavaScript-ni yuklaganingizga ishonch hosil qiling.
  • Agar siz bizning JavaScript-ni manbadan yaratayotgan bo'lsangiz, u talab qiladiutil.js . Kompilyatsiya qilingan versiya buni o'z ichiga oladi.
  • .alert-dismissibleOgohlantirishning o'ng tomoniga qo'shimcha to'ldirish qo'shadigan va tugmani joylashtiradigan o'chirish tugmasi va sinfni qo'shing .close.
  • O'chirish tugmachasida data-dismiss="alert"JavaScript funksiyasini ishga tushiradigan atributni qo'shing. <button>Barcha qurilmalarda to'g'ri harakat qilish uchun u bilan elementdan foydalanganingizga ishonch hosil qiling .
  • .fadeOgohlantirishlarni o'chirishda ularni jonlantirish uchun va .showsinflarini qo'shishni unutmang .

Siz buni jonli demo bilan amalda ko'rishingiz mumkin:

<div class="alert alert-warning alert-dismissible fade show" role="alert">
  <strong>Holy guacamole!</strong> You should check in on some of those fields below.
  <button type="button" class="close" data-dismiss="alert" aria-label="Close">
    <span aria-hidden="true">&times;</span>
  </button>
</div>

JavaScript harakati

Triggerlar

JavaScript orqali ogohlantirishni o'chirishni yoqing:

$('.alert').alert()

Yoki yuqorida ko'rsatilgandek alert ichidagi tugmadagidata atributlar bilan :

<button type="button" class="close" data-dismiss="alert" aria-label="Close">

Usullari

Usul Tavsif
$().alert() Atributga ega boʻlgan avlod elementlaridagi bosish hodisalari haqida ogohlantirishni tinglaydi data-dismiss="alert". (Data-api-ning avtomatik ishga tushirilishidan foydalanilganda kerak emas.)
$().alert('close') Ogohlantirishni DOMdan olib tashlash orqali yopadi. Agar elementda .fadeva .showsinflari mavjud bo'lsa, ogohlantirish o'chirilishidan oldin o'chadi.
$().alert('dispose') Elementning ogohlantirishini yo'q qiladi. 
$(".alert").alert('close')

Voqealar

Bootstrap-ning ogohlantirish plagini ogohlantirish funksiyasiga ulanish uchun bir nechta hodisalarni ochib beradi.

Tadbir Tavsif
close.bs.alert Ushbu hodisa closemisol usuli chaqirilganda darhol ishga tushadi.
closed.bs.alert Ogohlantirish yopilgandan so'ng, bu hodisa ishga tushiriladi (CSS o'tishlari tugashini kutadi). 
$('#myAlert').on('closed.bs.alert', function () {
  // do something…
})
