Passing JSON object from $http.get to function

Question

I have a JSON object which I load using $http.get like this:

$http.get("getData.php")//getData.php returns a J son file
    .success(function(response) {$scope.data = response;});

The JSON looks like this:

{
    "1": {
        "1": "*/3 * * * *",
        "2": "*/6 * * * *",
        "3": "*/3 * * * *",
        "4": "* * * * *"
    },
    "2": {
        "1": "*/3 * * * *",
        "2": "*/2 * * * *",
        "3": "*/3 * * * *",
        "4": "* * * * *"
    }
}

How can I pass this object to a function under the same controller and access its content?

I tried a few variations, most intuitive was this:

   $scope.compare = function (data){
        return data[1][1];
    }

But none of my attempts worked.

data[0][0] does not reference any items in your JSON object.

data[1][1] would return "*\/3 * * * *"
data[1][2] would return "*\/6 * * * *"

In the square brackets, you need to use the keys you defined in the JSON object because this data is an object, not an array.

Without seeing your full application running, this will be difficult to debug (your issue could be that data is being referenced in the function before it gets a value assigned to it). Can you check in your function to ensure data actually has a value? (i,e, console.log(data);... this will tell you if data is being passed properly.)

guessing its kind of stupid but how can i get the number of the array?

I played around with the circumstance of your application in angular a bit and I think if you handle your compare function a little differently it might work better: $scope.compare = function() { return $scope.data[1][1]; } DEMO

@Al.s what do you mean by the 'number of the array'?

The array starts with "1".

Try:

data["1"]["1"]

or

data[1][1]
