Hi all,
try this example to Use WebService with Javascript to Get Auto DateTime
1) open vs2008 and create a new web site and add new WebService name it “WebService.asmx” and add this code :-
using System;
using System.Collections;
using System.Linq;
using System.Web;
using System.Web.Services;
using System.Web.Services.Protocols;
using System.Xml.Linq;
/// <summary>
/// Summary description for WebService
/// </summary>
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
// 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 WebService : System.Web.Services.WebService {
public WebService () {
//Uncomment the following line if using designed components
//InitializeComponent();
}
[WebMethod]
public string GetTime()
{
return DateTime.Now.ToString("dd/MM/yyyy hh:mm:ss");
}
}
2) Add new Web Page and in ASPX Design add this :-
<head runat="server">
<title>Untitled Page</title>
<script type="text/javascript" language="javascript">
var interval = 0;
function pageLoad() {
callWebService();
interval = window.setInterval("callWebService()", 3000);
}
function callWebService() {
WebService.GetTime(successCallback, failCallback);
}
function successCallback(result) {
var divOutput = document.getElementById("divOutput");
divOutput.innerHTML = result;
}
function failCallback(error) {
alert('Error: ' + error.get_exceptionType());
}
</script>
</head>
<body>
<form id="form1" runat="server">
<asp:ScriptManager runat="server" ID="scriptManager1">
<Services>
<asp:ServiceReference Path="~/WebService.asmx" />
</Services>
</asp:ScriptManager>
<div id="divOutput">
</div>
</form>
</body>
then run your page you will find time change every 3 sec this is because i call the result from webservice
Hope this helps
Good Luck
