点击.trash_can按钮隐藏选中的li标签

Answer 1

Buat tatasusunan kosong untuk menyimpan indeks data yang anda perlu padamkan, seperti delProds

Tambah ng-klik pada kotak pilihan anda
Apabila dicetuskan, tolak indeks produk ini ke tatasusunan delProds apabila ia dinilai sebagai benar
Apabila ia palsu, padamkannya daripada delProds

Kemudian apabila anda mengklik butang padam, hanya padamkan semua data dengan nombor siri yang sepadan

Answer 2

Gunakan splice(), seperti products_mes.splice(subskrip, 1) untuk memadamkan item dalam tatasusunan

Answer 3

$scope.remove = function(idx) {
    $scope.products_mes.splice(idx, 1);
}

Answer 4

var index = products_mes.indexOf(data);
products_mes.splice(index,1);
data: untuk objek yang dipilih

Answer 5

splice
