从JavaScript中的对象数组中获取特定值？
假设以下是我们的对象数组：
const details =
[
{
employeeFirstName: "John",
employeeLastName: "Doe"
},
{
employeeFirstName: "David",
employeeLastName: "Miller"
},
{
employeeFirstName: "John",
employeeLastName: "Smith"
}
]示例
以下是获取特定值的代码，在这种情况下，其名字为“John”-
const details =
[
{
employeeFirstName: "John",
employeeLastName: "Doe"
},
{
employeeFirstName: "David",
employeeLastName: "Miller"
},
{
employeeFirstName: "John",
employeeLastName: "Smith"
}
]
for (var index = 0; index < details.length; index++) {
if (details[index].employeeFirstName === "John") {
console.log("FirstName=" + details[index].employeeFirstName + " LastName= " + details[index].employeeLastName);
}
}要运行以上程序，您需要使用以下命令-
node fileName.js.
在这里，我的文件名为demo223.js。
输出结果
输出如下-
PS C:\Users\Amit\JavaScript-code> node demo223.js FirstName=John LastName= Doe FirstName=John LastName= Smith
