Ta’rif va qo‘llanilishi
v-cloak direktivasi kompilyatsiya tugaguniga qadar kontentni yashirish uchun ishlatiladi.
Odatda v-cloak sahifa yuklanayotganda foydalanuvchi kompilyatsiya qilinmagan kontentning, jumladan jingalak qavslarning miltillab ko‘rinishini ko‘rmasligini ta’minlaydi.
Kompilyatsiya qilinmagan kontentni yashirish uchun element v-cloak bilan belgilanadi va kompilyatsiya tugaguniga qadar bu kontentni yashiradigan CSS qoidalari yoziladi.
v-cloak direktivasi faqat brauzerda kompilyatsiya qilinadigan Vue kodi uchun ishlaydi, shuning uchun SFC (*.vue) fayllari bilan ishlaganda u foydasiz.
