js调用webservice

    方法一:js中直接调用

     

    <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head id="Head1" runat="server">    <title>测试javascript调用WebService</title>    <script type="text/javascript" language=javascript>    function test()    {        //实际上HelloWorld函数中只有一个参数,这里的第2个"test2"是用来接收返回值的        //如果没有返回值则不需要        WebService.HelloWorld("Qinggeer",test2);    }    function test2(str)    {                    alert(str);    }    </script></head><body>    <form id="form1" runat="server">    <asp:ScriptManager ID="ScriptManager1" runat="server">        <Services>            <asp:ServiceReference Path="WebService.asmx" />        </Services>    </asp:ScriptManager>    <input id="Button1" type="button" value="button" οnclick="javascript:test();" />    </form></body></html>WebService代码:using System;using System.Web;using System.Collections;using System.Web.Services;using System.Web.Services.Protocols;/// <summary>/// WebService 的摘要说明/// </summary>[WebService(Namespace = "http://tempuri.org/")][WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)][System.Web.Script.Services.ScriptService]public class WebService : System.Web.Services.WebService {    public WebService () {        //如果使用设计的组件,请取消注释以下行         //InitializeComponent();     }    [WebMethod]    public string HelloWorld(string str) {        return str;    }    [WebMethod]    public string SayHello(string Name)    {        return "Hello " + Name;    }}

     

    方法二:ajax调用

    using System;   using System.Web;   using System.Web.Services;   using System.Web.Services.Protocols;     [webservice(namespace = "http://tempuri.org/")]   [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]   public class Service : System.Web.Services.WebService   {       public Service ()        {           //uncomment the following line if using designed components            //InitializeComponent();        }         [webmethod]       public string SayHelloTo(string Name)        {           return "Hello "+Name;       }   } 

     

    function RequestByGet(data){   var xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");   //Webservice location.  var URL="http://localhost:1323/WebSite6/Service.asmx/SayHelloTo?Name=Zach";  xmlhttp.Open("GET",URL, false);   xmlhttp.SetRequestHeader ("Content-Type","text/xml; charset=utf-8");   xmlhttp.SetRequestHeader ("SOAPAction","http://tempuri.org/SayHelloTo");   xmlhttp.Send(data);   var result = xmlhttp.status;   //OK  if(result==200) {    document.write(xmlhttp.responseText);   }   xmlhttp = null;  }

     

     

    ajax调用webservice,仍然在xmlHttp.Open()方法中拼凑url来访问
