Duyệt mảng đối tượng, kiểm tra customerId % 2 != 0 để lọc ID lẻ.
Ví dụ
var customerDetails = [
{ customerId: 101, customerName: "John" },
{ customerId: 102, customerName: "David" },
{ customerId: 103, customerName: "Mike" },
{ customerId: 104, customerName: "Bob" }
];
for (var index = 0; index < customerDetails.length; index++) {
if (customerDetails[index].customerId % 2 != 0) {
console.log("Customer ID: " + customerDetails[index].customerId);
console.log("Customer Name: " + customerDetails[index].customerName);
console.log("-----------------------------------");
}
}
Cách chạy
node demo.js
Kết quả
Customer ID: 101
Customer Name: John
-----------------------------------
Customer ID: 103
Customer Name: Mike
-----------------------------------
Cách hiện đại (ES6+):
customerDetails
.filter(c => c.customerId % 2 !== 0)
.forEach(c => console.log(`ID: ${c.customerId}, Name: ${c.customerName}`));
