为在对象内使用 for 循环迭代以获取具有奇数 CustomerId 的记录 JavaScript 中 for 循环的迭代 ?
假设如下是我们的对象 -
var customerDetails= [ { customerId:101, customerName:"John" }, { customerId:102, customerName:"David" }, { customerId:103, customerName:"Mike" }, { customerId:104, customerName:"Bob" } ]
与以下条件一起使用 for 循环,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,你需要使用以下命令 -
node fileName.js.
此处,我的文件名是 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 -----------------------------------------------------------
