Figuring out what Javascript object is this?

I have some script that has the following code:

var result = {
    id:   'test',
    name: 'test',
    home: 'test',
ex_info: [{date: new Date('12-31-2010'), quantity: 976}],
    status: ''
}

I am trying to insert information in the ex_info property. But I can't add anything. I try to hard to code the following:

var result = {
    id:   'test',
    name: 'test',
    home: 'test',
ex_info: [{date: new Date('03-31-2010'), quantity: 976}, {date: new Date('02-31-2010'), quantity: 543}],
    status: ''
}

But it results in an error:

Update:

Error: Expected [ { date : Date(Fri Mar 31 2010 00:00:00 GMT-0500 (EST)), quantity : 976 }开发者_开发技巧, { date : Date(Thu Mar 03 2011 00:00:00 GMT-0500 (EST)), quantity : 543 } ] to equal [ { date : Date(Fri Mar 31 2010 00:00:00 GMT-0500 (EST), quantity : 976 } ]

That's the correct way to append item to ex_info array.

Probably the code using "result" does not support more than one item in that array.

Your variable test is undefined. I imagine you meant to encompass that in a string:

var result = {
    id:   'test',
    name: 'test',
    home: 'test',
ex_info: [{date: new Date('03-31-2010'), quantity: 976}, {date: new Date('02-31-2010'), quantity: 543}],
    status: ''
}

There are four ways of instantiating a date:

• new Date() = current date and time

• new Date(ms) = milliseconds since 1970/01/01

• new Date(dateString)

• new Date(year, month, day, hours, minutes, seconds, milliseconds)
