I have a javascript object that contains addresses as follows

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"}
]

I want to add another "address" to it so i have somthing like the following

[
{"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"}
]

i cant figure out how to do this ?

Answer 1

使用Array#push将新对象添加到数组中：

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

It's not clear to me what you're encountering, but the probable problem you're running into is that the first snippet you give is a javascript Object, and the second snippet is an Array. You'd need to so something like:

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

You could then iterate over the list using a forEach:

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

You can read more about Arrays on the MDN

Answer 3

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