如何动态创建JavaScript数组（JSON格式）？

我们的对象数组

var someData = [   {firstName: "Max", lastName: "Mustermann", age: 40},   {firstName: "Hagbard", lastName: "Celine", age: 44},   {firstName: "Karl", lastName: "Koch", age: 42},];

与…有关

var employees = {    accounting: []};for(var i in someData) {    var item = someData[i];    employees.accounting.push({         "firstName" : item.firstName,        "lastName"  : item.lastName,        "age"       : item.age     });}

或使用

Array.prototype.map()

var employees = {    accounting: []};someData.map(function(item) {employees.accounting.push({         "firstName" : item.firstName,        "lastName"  : item.lastName,        "age"       : item.age     });}
