我已经创建了一个C#网络服务，我正试图调用它并从JavaScript脚本中使用它，请问这是什么方式或最好的实现方式，请提前感谢。
我会解释更多:
这是Web服务:

 public class DocumentInfo : System.Web.Services.WebService
{

    [WebMethod(EnableSession = true)]
    [ScriptMethod(ResponseFormat = System.Web.Script.Services.ResponseFormat.Json)]
    public string GetDocumentInfo(string id)
    {
        Document document = new Document(Int32.Parse(id));
        string output = JsonConvert.SerializeObject(document);
        return output;
    }
}

我已经对其进行了测试，当我尝试了建议的Ajax解决方案时，它出现了此错误500 Internal Server Error。

         failure: ajaxCallFailed
      });
    }
    catch (e)
    {
        alert('failed to call web service. Error: ' + e);
    }
}

function SuccessTestService(responce) {
    alert(eval(responce.d));
}


function ajaxCallFailed(error) {
        alert('error: ' + error);

    }
