js调用webservice中的方法

webservice代码：

 1 using System;
 2 using System.Web;
 3 using System.Collections;
 4 using System.Web.Services;
 5 using System.Web.Services.Protocols;
 6 using System.Web.Script.Services;
 7 using StoreHouse.Common;
 8 using StoreHouse.IDAL;
 9 using StoreHouse.Model;
10 using System.Data.SqlClient;
11 using System.Data;
12 using System.Xml;
13 using System.Collections.Generic;
14 using System.Runtime.InteropServices;
15 using System.Net.NetworkInformation;  
16 
17 /// <summary>
18 /// PageService 的摘要说明
19 /// </summary>
20 [WebService(Namespace = "http://tempuri.org/")]
21 [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
22 [ScriptService]
23 public class PageService : System.Web.Services.WebService
24 {
25     ArrayList al = new ArrayList();
26     public PageService()
27     {
28 
29         //如果使用设计的组件，请取消注释以下行 
30         //InitializeComponent(); 
31     }
32     /// <summary>
33     /// 添加收藏
34     /// </summary>
35     /// <param name="fid">产品ID</param>
36     /// <param name="sid">用户ID</param>
37     /// <param name="flag">标识（产品收藏、企业收藏、电子样本收藏、图库收藏）</param>
38     /// <returns>返回收藏状态</returns>
39     [WebMethod]
40     public int AddCollect(int fid,int sid,int flag)
41     {
42         IProductDataProvider ipdp = ProviderManager.Create<IProductDataProvider>();
43         IEnterpriseDataProvider iedp = ProviderManager.Create<IEnterpriseDataProvider>();        
44         if (flag == 1)
45         {
46             ProductCollect pc = new ProductCollect();
47             pc.ProductID = fid;
48             pc.UserID = sid;
49             pc.AddDatetime = DateTime.Now;
50             pc.UpdateDatetime = DateTime.Now;
51             return ipdp.AddProductCollect(pc);
52         }
53         else if (flag == 2)
54         {
55             EnterpriseCollect ec = new EnterpriseCollect();
56             ec.EnterpriseID = fid;
57             ec.UserID = sid;
58             ec.AddDatetime = DateTime.Now;
59             ec.UpdateDatetime = DateTime.Now;
60             return iedp.AddEnterpriseCollect(ec);
61         }
62         else if (flag == 3)
63         {
64             EElecSampleCollect epesc = new EElecSampleCollect();
65             epesc.EElecSampleID = fid;
66             epesc.UserID = sid;
67             epesc.AddDatetime = DateTime.Now;
68             epesc.UpdateDatetime = DateTime.Now;
69             return ipdp.AddEElecSampleCollect(epesc);
70         }
71         else if (flag == 4)
72         {
73             EPAtlasCollect epac = new EPAtlasCollect ();
74             epac.EPAtlasID= fid;
75             epac.UserID = sid;
76             epac.AddDatetime = DateTime.Now;
77             epac.UpdateDatetime = DateTime.Now;
78             return ipdp.AddEPAtlasCollect(epac);
79         }
80         return 000000;
81     }

js代码：

1 function AddAnswerResult(result) {
2     document.getElementById('dlAnswer').innerHTML += "<table Width='100%'>" + result + "</table>";
3 
4     document.getElementById('taAnswerContent').value = "";
5     alert('提交成功');
6 }

页面代码：

 1 <body>
 2     <form id="form1" runat="server">
 3     <asp:ScriptManager ID="ScriptManager1" runat="server" EnablePageMethods="true">
 4         <Services>
 5             <asp:ServiceReference Path="../Service/PageService.asmx" />
 6         </Services>
 7     </asp:ScriptManager>
 8 
 9                     <asp:Label ID="dlAnswer" runat="server" Style="word-wrap: break-word; word-break: normal;
10 
11 </body>

最后在配置文件中需要添加：

1 <system.web>
2 <httpHandlers>
3             <remove verb="*" path="*.asmx"/>
4             <add verb="*" path="*.asmx" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
5             
6         </httpHandlers>
7 </system.web>

这样，在客户端脚本中就可以直接调用 Web 服务的方法了。
