Menu
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>
Add in the error function to the ajax call... Hopefully you'll get some info back, as to why the call failed.
Are you using firebug? Watch the net tab.
$.ajax({
type: "POST",
url: url,
async: false,
data: jsonEncodedParams,
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (msg) {
}, //success
error: function (XMLHttpRequest, textStatus, errorThrown) {
if (textStatus == "timeout") {
alert('The request timed out, please resubmit');
} //if
else {
alert(errorThrown);
} //else
} //error
}); //ajax
