の出力dataは

Object
    data: Array[25]
        0: Object
            contentTypes: Array[4]
            creationDate: "2012-05-31T20:21:20.532+0000"

        1: Object

しかし、出力しようとすると、data[0]またはdata[1]すべてが として返されundefinedます。この JSON オブジェクトの処理方法がわかりません。

の出力alert(data)は

[Object object]

したがって、適切にフォーマットされた JSON オブジェクトであると想定しています。

ここに出力 JSON.stringify(data) があります

文字列化データを出力していて、その中に data という名前の配列がある場合は、data[0] の代わりに data.data[0] を実行する必要があります。

次のように言うと、もう少し明確になります。

success: function(result, status, xhr){
  var data = result.data;

その後、 data[0] は問題なく機能します。
