Ta’rif va qo‘llanilishi
ng-selected direktivasi <select> ro‘yxatidagi <option> elementining selected atributini o‘rnatadi.
Agar ng-selected atributi ichidagi ifoda true qaytarsa, variant tanlangan (selected) bo‘ladi.
Qiymatni true va false o‘rtasida almashtira olish uchun ng-selected direktivasi zarur. HTML’da selected atributini false qiymatiga o‘rnatib bo‘lmaydi (selected atributining mavjudligining o‘zi, qiymatidan qat’i nazar, elementni tanlangan holga keltiradi).
Sintaksis
<option ng-selected="expression"></option>
<option> elementi tomonidan qo‘llab-quvvatlanadi.
