如何从AJAX调用返回的第二个对象中获取值

Question

data对象在每个对象中有2个对象，有多个数组。我想从第二个数组的第二个对象获取值。

$.ajax({

    type: 'GET',
    url: 'api/First.getUniStructure',
    ContentType: 'application/json; charset=utf-8',
    dataType: 'json',

    success: function (data) {
        debugger;
        console.log(data);

        var collage = data[0].collages[0].Name;

        console.log(collage);

        var oTable = $('#exampleTable').DataTable({

            data: data,

            columnDefs: [
                { targets: [2], data: data[0].collages[0].name }                            
            ],

            columns: [
               { data: "ID" },
               { data: "Name" },
               { data: null }
            ]

        });
    }

});
