Ta’rif va qo‘llanilishi

$attrs obyekti komponent tegida berilgan fallthrough atributlar va hodisa tinglovchilarini ifodalaydi.

Agar root element komponent tegida berilgan fallthrough atributlar va hodisa tinglovchilarini meros qilib olishini istasak, o‘sha elementda v-bind="$attrs" ifodasidan foydalanamiz.

$attrs obyekti faqat o‘qish uchun mo‘ljallangan.

Fallthrough atributlar — komponent tegida berilgan atributlar (props emas) bo‘lib, ular komponentning root elementiga o‘tadi. Agar komponentda bir nechta root element bo‘lsa, fallthrough atributlarni qaysi element meros qilib olishi kerakligini belgilash uchun $attrs obyektidan foydalanamiz. Fallthrough atributlar haqida darslikda batafsil bilib oling.
