A very simple web service to add 2 numbers:
<%@ WebService Language="C#" class=MyMath %>
using System;
using System.Web.Services;
public class MyMath
{
[WebMethod]
public int add(int a, int b)
{
return a + b;
}
[WebMethod]
public int subtract(int a, int b)
{
return a - b;
}
}
A simple test page:
<html>
<head>
<script language="JavaScript">
var iCallID;
function init()
{
service.useService("ws2.asmx?WSDL","math");
}
function onmyresult()
{
if((event.result.error)&&(iCallID==event.result.id))
{
var xfaultcode = event.result.errorDetail.code;
var xfaultstring = event.result.errorDetail.string;
var xfaultsoap = event.result.errorDetail.raw;
// Add code to output error information here
alert("Error ");
}
else
{
service.innerHTML= "The method returned the result : " + event.result.value;
}
}
function tst()
{
iCallID = service.math.callService("Add",ip1.value,ip2.value);
}
</script>
</head>
<body onload="init();">
<BR>
Enter first Value <input type='text' id='ip1'>
<BR>
Enter Second value <input type='text' id='ip2'>
<BR>
<button onclick=javascript:tst()>Call Add Web Method</button>
<div id="service" style="behavior:url(webservice.htc)" onresult="onmyresult();">
</div>
</body>
</html>
