javascript - Ajax.Utility.RegisterTypeForAjax 未注册 ajax 类型

Question

当我使用 Ajax.Utility.RegisterTypeForAjax 时，出现错误。错误消息说:处理回调函数时出错。自动刷新终止。错误:“MyAjaxClass”未定义。我的代码如下所示:

public class MyAjaxClass
{
   Ajax.AjaxMethod(Ajax.HttpSessionStateRequirement.ReadWrite
    public string SaveData (int count)
    {
        return something;
    }

}
public partial class webaccess: Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        Ajax.Utility.RegisterTypeForAjax(typeof(MyAjaxClass));
    }
}

I added below config handlers in web.config.
 <system.webServer>    
    <validation validateIntegratedModeConfiguration="false" />
      <modules>
        <add name="ScriptModule" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
      </modules>
      <handlers>
        <remove name="WebServiceHandlerFactory-Integrated" />
        <add verb="POST,GET" name="Ajax" path="ajax/*.ashx" type="Ajax.PageHandlerFactory, Ajax" />
        <add name="ScriptHandlerFactory" verb="*" path="*.asmx"  type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
        <add name="ScriptHandlerFactoryAppServices" verb="*" path="*_AppService.axd"   type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
        <add name="ScriptResource"  verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
      </handlers>
   </system.webServer>

请让我知道我还能做什么。

Answer 1

代码中的语法错误

 Ajax.AjaxMethod(Ajax.HttpSessionStateRequirement.ReadWrite

替换为

  [Ajax.AjaxMethod(Ajax.HttpSessionStateRequirement.ReadWrite)]
