Foydalanish imkoniyati

aria-expandedBoshqaruv elementiga qo'shishni unutmang . Bu atribut boshqaruvga bogʻlangan yigʻiladigan elementning joriy holatini ekranni oʻqish moslamalariga va shunga oʻxshash yordamchi texnologiyalarga aniq etkazadi. Agar yig'iladigan element sukut bo'yicha yopilgan bo'lsa, boshqaruv elementidagi atribut qiymati ga ega bo'lishi kerak aria-expanded="false". Agar siz yig'iladigan elementni showsinfdan foydalanib, sukut bo'yicha ochiq qilib qo'ygan bo'lsangiz, aria-expanded="true"uning o'rniga boshqaruvni o'rnating. Plagin yig'iladigan element ochilgan yoki yopilmaganligiga (JavaScript orqali yoki foydalanuvchi bir xil yig'ish elementiga bog'langan boshqa boshqaruv elementini ishga tushirgani uchun) avtomatik ravishda boshqaruv elementida ushbu atributni almashtiradi. Agar boshqaruv elementining HTML elementi tugma bo'lmasa (masalan, <a>yoki <div>), atributrole="button"elementga qo'shilishi kerak.

Agar sizning boshqaruv elementingiz bitta yig'iladigan elementga mo'ljallangan bo'lsa - ya'ni atribut selektorga data-targetishora qilsa - siz yig'iladigan elementni o'z ichiga olgan boshqaruv elementiga atributni qo'shishingiz kerak . Zamonaviy ekran o'quvchilari va shunga o'xshash yordamchi texnologiyalar foydalanuvchilarga to'g'ridan-to'g'ri yig'iladigan elementga o'tish uchun qo'shimcha yorliqlar bilan ta'minlash uchun ushbu atributdan foydalanadi.idaria-controlsid

E'tibor bering, Bootstrap-ning joriy tatbiqi WAI-ARIA Authoring Practices 1.1 akkordeon naqshida tasvirlangan turli xil klaviatura o'zaro ta'sirlarini qamrab olmaydi - ularni o'zingiz maxsus JavaScript-ga qo'shishingiz kerak bo'ladi.

Foydalanish

Yiqilish plagini og'ir yuklarni ko'tarish uchun bir nechta sinflardan foydalanadi:

  • .collapsemazmunini yashiradi
  • .collapse.showmazmunini ko‘rsatadi
  • .collapsingo'tish boshlanganda qo'shiladi va tugashi bilan o'chiriladi

Ushbu sinflarni quyidagi manzilda topish mumkin _transitions.scss.

Ma'lumotlar atributlari orqali

Bir yoki bir nechta yig'iladigan elementlarning boshqaruvini avtomatik belgilash uchun elementga data-toggle="collapse"va a qo'shing . data-targetAtribut data-targetsiqishni qo'llash uchun CSS selektorini qabul qiladi. collapseSinfni yig'iladigan elementga qo'shganingizga ishonch hosil qiling . Agar siz uni sukut bo'yicha ochishni istasangiz, qo'shimcha sinfni qo'shing show.

Akkordeonga o'xshash guruh boshqaruvini yig'iladigan maydonga qo'shish uchun ma'lumotlar atributini qo'shing data-parent="#selector". Buni amalda ko'rish uchun demoga qarang.

JavaScript orqali

Qo'lda yoqish:

$('.collapse').collapse()
