js调用webservice中的方法实现思路及代码

webservice代码：复制代码代码如下: using System; using System.Web; using System.Collections; using System.Web.Services; using System.Web.Services.Protocols; using System.Web.Script.Services; using StoreHouse.Common; using StoreHouse.IDAL; using StoreHouse.Model; using System.Data.SqlClient; using System.Data; using System.Xml; using System.Collections.Generic; using System.Runtime.InteropServices; using System.Net.NetworkInformation; /// <summary> /// PageService 的摘要说明 /// </summary> [WebService(Namespace = "http://tempuri.org/")] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] [ScriptService] public class PageService : System.Web.Services.WebService { ArrayList al = new ArrayList(); public PageService() { //如果使用设计的组件，请取消注释以下行 //InitializeComponent(); } /// <summary> /// 添加收藏 /// </summary> /// <param name="fid">产品ID</param> /// <param name="sid">用户ID</param> /// <param name="flag">标识（产品收藏、企业收藏、电子样本收藏、图库收藏）</param> /// <returns>返回收藏状态</returns> [WebMethod] public int AddCollect(int fid,int sid,int flag) { IProductDataProvider ipdp = ProviderManager.Create<IProductDataProvider>(); IEnterpriseDataProvider iedp = ProviderManager.Create<IEnterpriseDataProvider>(); if (flag == 1) { ProductCollect pc = new ProductCollect(); pc.ProductID = fid; pc.UserID = sid; pc.AddDatetime = DateTime.Now; pc.UpdateDatetime = DateTime.Now; return ipdp.AddProductCollect(pc); } else if (flag == 2) { EnterpriseCollect ec = new EnterpriseCollect(); ec.EnterpriseID = fid; ec.UserID = sid; ec.AddDatetime = DateTime.Now; ec.UpdateDatetime = DateTime.Now; return iedp.AddEnterpriseCollect(ec); } else if (flag == 3) { EElecSampleCollect epesc = new EElecSampleCollect(); epesc.EElecSampleID = fid; epesc.UserID = sid; epesc.AddDatetime = DateTime.Now; epesc.UpdateDatetime = DateTime.Now; return ipdp.AddEElecSampleCollect(epesc); } else if (flag == 4) { EPAtlasCollect epac = new EPAtlasCollect (); epac.EPAtlasID= fid; epac.UserID = sid; epac.AddDatetime = DateTime.Now; epac.UpdateDatetime = DateTime.Now; return ipdp.AddEPAtlasCollect(epac); } return 000000; }

jQuery 的 data API 实现方式有缓存数据的效果使用 IE 7 （IE8+ 在控制台切换至IE7 模式），当DOM 节点有自定义数据属性时，检查 DOM 节点即可看到形如 jQuery18305664906559272507 的属性，这便是用于从数据存>>>详细阅读
