附加到对象 [英] Appending to an object

问题描述

我有一个可以容纳警报和有关警报的信息的对象:

I have an object that holds alerts and some information about them:

var alerts = { 
    1: { app: 'helloworld', message: 'message' },
    2: { app: 'helloagain', message: 'another message' }
}

除此之外，我还有一个变量，表示有多少警报，alertNo.我的问题是，当我要添加新警报时，是否可以将警报附加到alerts对象上?

In addition to this, I have a variable that says how many alerts there are, alertNo. My question is, when I go to add a new alert, is there a way to append the alert onto the alerts object?

推荐答案

如何将警报作为记录而不是单个对象的属性存储在数组中?

How about storing the alerts as records in an array instead of properties of a single object ?

var alerts = [ 
    {num : 1, app:'helloworld',message:'message'},
    {num : 2, app:'helloagain',message:'another message'} 
]

然后添加一个，只需使用push:

And then to add one, just use push:

alerts.push({num : 3, app:'helloagain_again',message:'yet another message'});
