动态添加到Javascript对象

Question

I have a Javascript object that looks like this. 我有一个看起来像这样的Javascript对象。

ips[ipID] = {}

So I end up with a bunch of ips that need to store information that will look like 所以我最终得到了一堆需要存储看起来像的信息的ips

ipID { name : 'val', anotherName : 'anotherVal' }

My question is, how do I dynamically add these names and values? 我的问题是，如何动态添加这些名称和值？

Answer 1

I believe this is the easiest thing to do if your names are dynamic: 我相信如果你的名字是动态的，这是最简单的事情：

var myobj = {};
var newFieldName = 'my new field name';
var newFieldValue = 'my new field value';
myobj[newFieldName] = newFieldValue;

Answer 2

var ipID = {};
ipID.name = 'val';
ipID.anotherName = 'anotherVal';

Answer 3

If you would like to use the great underscore library (a swiss army knife for js developers), you could use the extend method http://documentcloud.github.com/underscore/#extend . 如果你想使用伟大的下划线库（js开发人员的瑞士军刀），你可以使用扩展方法http://documentcloud.github.com/underscore/#extend 。

So for example 所以举个例子

var tmp = { name: "asdf", val: "value" };
_(ips[ipID]).extend(tmp);

Hope this is clear, it would be easier to help if you had a more precise question. 希望这很清楚，如果你有一个更精确的问题，它会更容易帮助。
