Tìm kiếm tuyến tính là một thuật toán tìm kiếm đơn giản và tuần tự. Nó được sử dụng để tìm xem một phần tử cụ thể có trong mảng hay không bằng cách duyệt qua mọi phần tử trong mảng. Trong khi tìm kiếm trong mảng 2D hoàn toàn giống nhau nhưng ở đây cần phải duyệt qua tất cả các ô Theo cách này, bất kỳ phần tử nào cũng được tìm kiếm trong mảng 2D.
Dưới đây là triển khai tìm kiếm tuyến tính trong mảng 2D

Làm cách nào để kiểm tra xem một phần tử có trong mảng 2D trong JavaScript không?
Phương thức indexof[] trong Javascript là một trong những cách thuận tiện nhất để tìm hiểu xem một giá trị có tồn tại trong một mảng hay không. Phương thức indexof[] hoạt động trên hiện tượng số chỉ mục. Phương thức này trả về chỉ mục của mảng nếu tìm thấy và trả về -1 nếu không.
Làm cách nào để kiểm tra xem giá trị có tồn tại trong mảng 2D không?
Cách kiểm tra xem giá trị có tồn tại trong mảng 2D hay không .
biến x = 2;
biến y = 3;
var allObjects = new GameObject[x,y];
for [var a = 0; a < x; a++] {
for [var b = 0; b < y; b++] {
// Gán đối tượng cho mảng 2D
allObjects[a,b] =. ;
Làm cách nào để kiểm tra giá trị tồn tại trong JavaScript mảng đa chiều?
Sử dụng Phương thức indexOf[]
. Nếu phần tử không tồn tại thì -1 được trả về.
Làm cách nào để kiểm tra xem một giá trị có tồn tại trong một mảng đối tượng trong JavaScript không?
Sử dụng phương thức include[] . Nếu mảng chứa một đối tượng/phần tử có thể được xác định bằng cách sử dụng phương thức include[]. Phương thức này trả về true nếu mảng chứa đối tượng/phần tử khác trả về false.
