jQuery Ajax 调用WebService出错解决方法

开发环境:

　　framework2.0,System.Web.Extensions.dll(版本号：1.0.61025.0)

ajax code:

$.ajax({

        type: "POST",

        url: webURL,

        data: jsonParam,

        contentType: "application/json; charset=utf-8",

        dataType: "json",

        success: function(data) {

            //callback();

        },

        error: function(msg) {

            alert(msg.ResponseText);

        }

    })

webservice

[WebService(Namespace = "http://tempuri.org/")]

    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]

    [System.ComponentModel.ToolboxItem(false)]

    [ScriptService]

    public class WebService1 : System.Web.Services.WebService

    {

        [WebMethod]

        [ScriptMethod(ResponseFormat = ResponseFormat.Json)]

        public string HelloWorld(string pageIndex, string pageSize)

        {

              //BLL code

        }

     }

如果这样的话前台是不能访问service的，你必须在config文件里加入下面一段代码：

<httpHandlers>

      <add verb="*" path="*.asmx" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions,Version=1.0.61025.0, Culture=neutral,PublicKeyToken=31bf3856ad364e35"/>

    </httpHandlers>
