如何使用jquery获取对象的值数组

Question

我有问题使用jquery获取对象数组中的所有元素...

我从互联网上获取此代码...

var id = 123;
var test = new Object();
test.Identification = id;
test.Group = "users";
test.Persons = new Array();

test.Persons.push({"FirstName":" AA ","LastName":"LA"});
test.Persons.push({"FirstName":" BB ","LastName":"LBB"});
test.Persons.push({"FirstName":" CC","LastName":"LC"});
test.Persons.push({"FirstName":" DD","LastName":"LD"});

如何使用JQuery获取人员中的"FirstName"和"LastName"？

Answer 1

你可以使用$.each()或$.map()取决于你想用它做什么.

$.map(Persons, function(person) {
    return person.LastName + ", " + person.FirstName;
});
// -> ["Doe, John", "Appleseed, Marc", …]
