Scrollspy
Bootstrap navigatsiyasini avtomatik ravishda yangilang yoki ko'rish oynasida qaysi havola faol ekanligini ko'rsatish uchun aylantirish holatiga qarab guruh komponentlarini ro'yxatlang.
Scrollspy to'g'ri ishlashi uchun bir nechta talablarga ega:
- Agar siz bizning JavaScript-ni manbadan yaratayotgan bo'lsangiz, u talab qiladi
util.js
. - U Bootstrap nav komponentida yoki ro'yxat guruhida ishlatilishi kerak .
- Scrollspy
position: relative;
siz josuslik qilayotgan elementni talab qiladi, odatda<body>
. - dan boshqa elementlarga josuslik qilayotganda , to'plam va qo'llanilishiga
<body>
ishonch hosil qiling.height
overflow-y: scroll;
- Ankrajlar (
<a>
) talab qilinadi va u bilan elementga ishora qilishi kerakid
.
Muvaffaqiyatli amalga oshirilgandan so'ng, navbat yoki ro'yxat guruhingiz mos ravishda yangilanadi .active
va ular bilan bog'liq maqsadlar asosida sinfni bir elementdan ikkinchisiga o'tkazadi.
Navbar ostidagi maydonni aylantiring va faol sinf o'zgarishini kuzating. Ochiladigan elementlar ham ta'kidlanadi.
