I need to access the "State" value from the following array --

data =   
{ 
    Images:
    [ 
        {
            ProductCodes: [],
            BlockDeviceMappings: [Object],
            Tags: [],
            ImageId: 'ami-75301c',
            ImageLocation: '54696560/Test Image 3',
            State: 'available',       
            VirtualizationType: 'pavirtul',
            Hypervisor: 'xen' 
        }
    ],
    requestId: '2eb809d3-7f82-4142-b5d1-6af3' 
}

When I try data.Images["State"] or data.Images.State I get undefined.

Thanks

• 1 Good, that means everything is working properly. Your Array referenced by Images has no State property. If you indent your structure cleanly, things may bee clear. – user2437417 Commented Jul 22, 2013 at 18:08
• How do I access the State value? I need'available'back. – Fox Commented Jul 22, 2013 at 18:10
• 1 Well, Images is referencing an Array, and an Array is an ordered collection of data accessible via 0-based indices. – user2437417 Commented Jul 22, 2013 at 18:10

Images maps to an array which stores objects, so you have to specify the index of the item you want. Try data.images[0]["State"].

You can access like this:

data.Images[0].State

Or even:

data.Images[0]['State']

Access the state with data.image[0].state. Your method was wrong because inside the image, you need an index within the two square bracket, the image property is an array.
