在 JavaScript 中，对象内部的 for 循环迭代如何获取具有奇数 CustomerId 的记录?

假设以下是我们的对象 −
var customerDetails=
[
{
customerId:101,
customerName:"John"
},
{
customerId:102,
customerName:"David"
},
{
customerId:103,
customerName:"Mike"
},
{
customerId:104,
customerName:"Bob"
}
]
使用 for 循环并结合以下条件，仅显示奇数 CustomerID 记录 −
for(var index=0;index<customerDetails.length;index++){
if(customerDetails[index].customerId % 2 !=0){
//
}
}
示例
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("---------------------------------------------------
--------")
}
console.log("");
}
要运行上述程序，您需要使用以下命令 −
node fileName.js.
这里，文件名是 demo71.js。
输出
这将产生以下输出 −
PS C:\Users\Amit\JavaScript-code> node demo71.js Customer Id=101 Customer Name=John ----------------------------------------------------------- Customer Id=103 Customer Name=Mike -----------------------------------------------------------
