Question

I am using rails 3 with backbone.js 0.53 and currently receive a GET with the following array:

[{"credit_card":
    {"id":2,"cc_number":"12345678912345","cc_type":"stack","owner":"overflow"}},
    ....next objects....]

I have read a lot of the other threads but can’t figure out how to access the values.
Is there any way to do this with the backbone-given methods like .get()?

I tried

myArray = eval(arrayJSON)
alert myArray.length #works

but any other way of accessing the single values in an array or iterating over it fails.
Probably I am just missing something here.

Quick example of how to iterate through all your results via underscore:

/* received results mocking */

model.attributes = [
    { "credit_card" : { "id":2, "cc_number":"12345678912345" },
    { "credit_card" : { "id":3, "cc_number":"44444444455555" },
    { "credit_card" : { "id":4, "cc_number":"66666655554332" }
]

/* lets get all results */

results = model.toJSON()

/* loop through all results */

_(results).each(item) {
    console.log(item.credit_card.id);
}

/* get result by array pos */

console.log(results[1]); // get 2nd item

Cheers
