using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Services;
namespace WebService1
{
/// <summary>
/// Summary description for Service1
/// </summary>
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.ComponentModel.ToolboxItem(false)]
// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.
// [System.Web.Script.Services.ScriptService]
public class Service1 : System.Web.Services.WebService
{
[WebMethod]
public int Add(int x,int y)
{
return x + y;
}
}
}
页面Javascript 如下
代码
<head runat="server">
<title></title>
<script language="javascript">
function Add() {
var x = document.getElementById("<%=Text1.ClientID%>").value;
var y = document.getElementById("<%=Text2.ClientID%>").value;
var data;
data = '<?xml version="1.0" encoding="utf-8"?>';
data = data + '<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">';
data = data + '<soap:Body>';
data = data + '<Add xmlns="http://tempuri.org/">';
data = data + '<x>' + x + '</x>';
data = data + '<y>' + y + '</y>';
data = data + '</Add>';
data = data + '</soap:Body>';
data = data + '</soap:Envelope>';
var xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
var URL = "http://localhost:1096/Service1.asmx";
xmlhttp.Open("POST", URL, false);
xmlhttp.SetRequestHeader("Content-Type", "text/xml; charset=gb2312");
xmlhttp.SetRequestHeader("SOAPAction", "http://tempuri.org/Add");
xmlhttp.Send(data);
document.getElementById("<%=Label1.ClientID%>").innerHTML = xmlhttp.responseText;
}
</script>
</head>
<body>
<form id="form1" runat="server">
<input id="Text1" type="text" runat="server"/>
<input id="Text2" type="text" runat="server"/>
<input id="Button1" type="button" value="Add" onclick ="Add()" />
