在JS里调用 Web service 里面的方法

用代码说明

解决方案 »

  1.   

    js:
    function GetLYDJ(zcFlag,fldwid,sldwid, cj, user, flcode, stime, etime,strkw,strLogenTime)
    {
        WebServiceInBound.SelectLydj(zcFlag,fldwid, sldwid, cj, user, flcode, stime, etime,strkw,strLogenTime,SetLYDJ,onBadMethodError)
    }
    webservice:
    [System.Web.Script.Services.ScriptService]//可在script中调用
    [WebMethod(Description = "Per session Hit Counter", EnableSession = true)]//可接收session
        public string SelectLydj(string zcFlag, string fldwid, string sldwid, string cj, string user, string flcode, string stime, string etime, string kw, string time)
        {...............................}

    楼上的需要安装Ajax扩展
    如果不想安装，那你可以使用ajax来调用Test WebService 类
    /// <summary>
        /// Service1 的摘要说明
        /// </summary>
        [WebService(Namespace = "http://tempuri.org/")]
        [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
        [ToolboxItem(false)]
        public class Service1 : System.Web.Services.WebService
        {
            
            [WebMethod]
            public string HelloWorld()
            {
                return "Hello World";
            }
        }
    default.aspx
     public partial class Default : System.Web.UI.Page
        {
            protected void Page_Load(object sender, EventArgs e)
            {
                Service1 s = new Service1();
                Response.Write(s.HelloWorld());
            }
        }
