javascript - Appending to an object

Question

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' }
}

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?

Answer 1

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'} 
]

And then to add one, just use push:

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