如何将json对象转换为json数组

Question

我从asana获取json，它是几个对象的对象（数据）。如何将数据作为数组？

{"data":{"id":5571422294129,"created_at":"2013-05-24T15:31:50.340Z","modified_at":"2013-05-24T15:32:21.260Z","name":"testProject","notes":"","archived":false,"workspace":{"id":5571305742112,"name":"TestITAT"},"followers":[{"id":5571289325327,"name":"John Doe"}]}}

我正在尝试使用aoColumns将其放入数据表中。如果不需要将“数据”转换为数组，请告诉我如何在没有它的数据表中使用此JSON。

这并不复杂。您可以使用DataTables aaData。我假设您的JSON包含多个"data":{..}, "data":{..}, "data":{..}？

然后，将其视为测试数据：

var data = [
{"data":{"id":1571422294129,"created_at":"2010-05-24T15:31:50.340Z","modified_at":"2010-05-24T15:32:21.260Z","name":"testProject","notes":"","archived":false,"workspace":{"id":5571305742112,"name":"TestITAT"},"followers":[{"id":5571289325327,"name":"John Doe"}]}},
{"data":{"id":2571422294129,"created_at":"2011-05-24T15:31:50.340Z","modified_at":"2011-05-24T15:32:21.260Z","name":"Project A","notes":"","archived":false,"workspace":{"id":5571305742112,"name":"TestITAT"},"followers":[{"id":5571289325327,"name":"John Doe"}]}},
{"data":{"id":3571422294129,"created_at":"2012-05-24T15:31:50.340Z","modified_at":"2012-05-24T15:32:21.260Z","name":"Project B","notes":"bla bla","archived":false,"workspace":{"id":5571305742112,"name":"TestITAT"},"followers":[{"id":5571289325327,"name":"John Doe"}]}}
];

HTML标记

 <table id="test">
   <thead>
     <tr>
        <th>archived</th>
        <th>created_at</th>
        <th>id</th>
        <th>modified_at</th>
        <th>name</th>
        <th>notes</th>
      </tr>
   </thead>
   <tbody>
   </tbody>
 </table>

将JSON转换为aaData-array ：

var aaData = [];
for (var i=0;i<data.length;i++) {
    aaData.push([ 
        data[i].data.archived,
        data[i].data.created_at,
        data[i].data.id,
        data[i].data.modified_at,
        data[i].data.name,
        data[i].data.notes
    ]);
}

初始化表格

$('#test').dataTable({
   "aaData": aaData
});

结果：

我不确定你究竟想做什么，但是......

如果您尝试将JSON反序列化为数据表，您需要这样的东西。这将采用您的JSON并将其反序列化为一个对象，它不会完全适用于数据表，而是使用DataContract和DataMember属性修饰的自定义类。但我认为这对你来说可能是一个很好的起点。

Public static T DeSerialize<T>(string strJSON)
{
      T obj = Activator.CreateInstance<T>(); 
      MemoryStream ms = new MemoryStream(Encoding.Unicode.GetBytes(strJSON));
      DataContractJsonSerializer serializer = new DataContractJsonSerializer(obj.GetType());
      obj = (T)serializer.ReadObject(ms);

      ms.Close();
      ms.Dispose();
      return (obj);
}

这是一篇关于序列化JSON的非常有用的文章。 HTH：）
