Pengikatan model v pada medan pemilih tarikh saya tidak berfungsi dengan betul.
Apabila anda membuat pilihan, ia akan dikemas kini secara langsung pada skrin tetapi ia tidak akan menyimpan nilai dalam objek reaktif formValues.
Memandangkan vee-validate tidak menyokong medan pemilih tarikh, bagaimanakah cara saya memaksanya untuk mengemas kini kepada komponen tindak balas yang sama (formValues) yang mana semua medan input saya yang lain dipetakan.
