I have a nested data structure / JSON, how can I access a specific value?

I have a service that returns nested Objects in a JSON Array. How can I loop through the objects and print the desired data?

This is my result:

[

{

    item1: {

        sourceUuid: 5599ffac-4b99-47c7-9370-a25e7e465429,

        targetUuid: 5599ffac-4b99-47c7-9370-a25e7effffff

    }

},

{

    item2: {

        sourceUuid: bf63fe50-8b2b-488d-b565-009fcaebdb45,

        targetUuid: -1

    }

},

{

    item3: {

        sourceUuid: 0005fd96-f654-4781-8602-09fedc0cdd35,

        targetUuid: 0005fd96-f654-4781-8602-09fedc0cdd35

    }

}

]

This is what I want to print for each item (item1, item2, item3, ...):

Item Name: item1

Source: 5599ffac-4b99-47c7-9370-a25e7e465429

Target: 5599ffac-4b99-47c7-9370-a25e7effffff

So far I tried:

for (var i = 0, length = data.length; i < length; i++) {

for (obj in data[i]) {

    console.log(obj);



}

}

This only returns item1, item2 etc. But I don't know how access sourceUuid etc. from there

You can loop the array with a for loop and the object properties with for-in loops.

for (var i=0; i<result.length; i++)

    for (var name in result[i]) {

        console.log(Item name: +name);

        console.log(Source: +result[i][name].sourceUuid);

        console.log(Target: +result[i][name].targetUuid);

    }
