Ta’rif va qo‘llanilishi
ng-repeat direktivasi HTML qismini berilgan son marta takrorlaydi.
HTML qismi to‘plamdagi har bir element uchun bir martadan takrorlanadi.
To‘plam massiv yoki obyekt bo‘lishi kerak.
Eslatma: Takrorlanishning har bir nusxasiga joriy elementdan iborat o‘z scope’i beriladi.
Agar sizda obyektlar to‘plami bo‘lsa, ng-repeat direktivasi har bir obyekt uchun bitta jadval qatorini va har bir obyekt xususiyati uchun bitta jadval katagini ko‘rsatadigan HTML jadvalini yaratish uchun juda mos. Quyidagi misolga qarang.
Sintaksis
<element ng-repeat="expression"></element>
Barcha HTML elementlari tomonidan qo‘llab-quvvatlanadi.
