Question

我有一个包含以下地址的javascript对象

var addressList = [
    {"AddressID":"10011","AddressType":"Delivery","AddressLine1":"4 Caerleon Drive","AddressLine2":"Bittern","AddressLine3":"","CityTown":"Southampton","County":"Hampshire","PostCode":"SO19 5LF","Country":"United Kingdom","ContactID":"10011"},
    {"AddressID":"10012","AddressType":"Home","AddressLine1":"526 Butts Road","AddressLine2":"Sholing","AddressLine3":"","CityTown":"Southampton","County":"Hampshire","PostCode":"SO19 1DJ","Country":"England","ContactID":"10011"}
]

我想为它添加另一个“地址”，所以我有类似下面的内容

[
{"AddressID":"10011","AddressType":"Delivery","AddressLine1":"4 Caerleon Drive","AddressLine2":"Bittern","AddressLine3":"","CityTown":"Southampton","County":"Hampshire","PostCode":"SO19 5LF","Country":"United Kingdom","ContactID":"10011"},
{"AddressID":"10012","AddressType":"Home","AddressLine1":"526 Butts Road","AddressLine2":"Sholing","AddressLine3":"","CityTown":"Southampton","County":"Hampshire","PostCode":"SO19 1DJ","Country":"England","ContactID":"10011"},
{"AddressID":"10013","AddressType":"Home","AddressLine1":"5436 Bfds Road","AddressLine2":"Sherly","AddressLine3":"","CityTown":"Southampton","County":"Hampshire","PostCode":"SO19 1DJ","Country":"England","ContactID":"10011"}
]

我无法弄清楚如何做到这一点？

Answer 1

使用Array#push向数组添加新对象：

addressList.push({"AddressID":"10013","AddressType":"Home","AddressLine1":"5436 Bfds Road","AddressLine2":"Sherly","AddressLine3":"","CityTown":"Southampton","County":"Hampshire","PostCode":"SO19 1DJ","Country":"England","ContactID":"10011"});

Answer 2

我不清楚你遇到了什么，但你遇到的可能问题是你提供的第一个片段是一个javascript对象，第二个片段是一个数组。你需要这样的东西：

var addressList = [];
addressList.push({"AddressID":"10011",...});

然后，您可以使用forEach迭代列表：

addressList.forEach(function(address) {
    alert(address.AddressID);
    doSomethingWithAddress(address);
});

Answer 3

addressList.push（{AddressID：1234，Country：'Foo'，...}）;

将对象添加到现有的javascript对象
