I have button and that jQuery script (to start the progress bar):

<script src="../_Files/JScripts/jquery-1.3.2.js" type="text/javascript"></script>
<script src="../_Files/JScripts/jquery-ui-1.7.2.custom.min.js" type="text/javascript"></script>

 var intervalID;
 $("#<%=this.Button1.ClientID%>").click(
            function() {

                intervalID = setInterval(updateProgress, 500);

                $.ajax({
                    type: "POST",
                    url: "CustomerImport.aspx/ExecuteImport",
                    data: "{}",
                    contentType: "application/json; charset=utf-8",
                    dataType: "json",
                    async: true,
                    success: function()
                    {
                        $("#progressbar").progressbar("value", 100);
                        clearInterval(intervalID);
                        $("#result").text('ok');
                    }
                });

                return false;
            }
        );

   function updateProgress() {

            $.ajax({
                type: "POST",
                url: "CustomerImport.aspx/GetProgress",
                data: "{}",
                contentType: "application/json; charset=utf-8",
                dataType: "json",
                async: true,
                success: function(msg) {
                    $("#result").text = msg.d;
                    var value = $("#progressbar").progressbar("option", "value");
                    if (value < 100) {
                        $("#progressbar").progressbar("value", msg.d);
                        $("#result").text(msg.d);
                    }
                    else {
                        clearInterval(intervalID);
                        window.location = window.location;
                    }
                }
            });
        }

the method:

    [System.Web.Services.WebMethod]
    public void ExecuteImport()
    {
        _Presenter.ExecuteImport();
    }

the problem is, that method is NOT being invoked. Why ?

When I replace the $.ajax for the e.g alert('ok'); the alert shows, so it works

    Did you decorate your service class with the [ScriptService] attribute? Also try changing the data parameter to: data: { }. What does FireBug says about this? Is there a request being sent? If yes what does the server respond?

    Also you have a mistake in your url (web services have the ASMX extension). You wrote:

    CustomerImport.aspx/ExecuteImport

    While it should be:

    CustomerImport.asmx/ExecuteImport

    Here’s a complete working example that you may adapt to your needs:

    Web service:

    [WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[ToolboxItem(false)]
[ScriptService]
public class CustomerImport : WebService
{
    [WebMethod]
    public void ExecuteImport()
    {
    }
}

    Calling web page:

    <%@ Page Language="C#" %>
<!doctype html>
<html>
<head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <title>Test</title>
    <script type="text/javascript" src="scripts/jquery-1.4.1.js"></script>
    <script type="text/javascript">
        $(function () {
            $.ajax({
                type: 'POST',
                url: '/CustomerImport.asmx/ExecuteImport',
                data: { },
                success: function () {
                    alert('ok');
                }
            });
        });
    </script>
</head>
<body>

    <form runat="server">

    </form>

</body>
</html>
