How to access the returned object of JQuery "POST" method in javascript?

Question

I have a JQuery "POST" method which returns value

Objects: [{"in_approved":0, "out_approved":0},{"in_approved":1, "out_approved":2}]

Ajax method:

$.ajax({
        data: {
                "start_date" : startDate,
                "end_date" : endDate
        },
        url: "/admin/analytics",
        type: 'POST',
        dataType: 'json',
        success: function(response)
        {

            // Accessing returned object

        },
        error : function(request, status, thrownError){
            alert("Error");
            return;
                }
    });

Now, to access the returned object I am using

$.each(response.data, function(index,row){
   var in_approved = row.in_approved; 
  alert(in_approved); // just to see if the value is being stored in the variable.
});

But when I do this I get an error:

Uncaught TypeError: Cannot read property 'length' of undefined

Can anyone explain to me what this error means?

Also how to access the values of the returned object?

response will be the array that you posted. It does not have a data property, so it will inevitably not be found when you look for it! Just loop through the array:

$.each(response, function(index,row){

The response is an array of Objects.. So you need to iterate over it as an array.

$.each(response, function(index,row){

But you are trying to iterate over response.data

your $.each will work on this object

data : [{"in_approved":0, "out_approved":0},{"in_approved":1, "out_approved":2}]
