Ajax call to Webmethod, cross domain - ajax

Question

I have two Asp projects. On close of a dialog box in project A I am trying to call a static webmethod in project B using ajax call.
Instead of calling the Webmethod it is calling the PageLoad.
Any ideas what I am doing wrong?
WebMethod
[WebMethod]
public static string UpdateSession()
{
return "Test";
}
$(function () {
$('div#DialogDiv').on('dialogclose', function (event) {
CloseDialog("http://localhost:1330/Application_Default.aspx/UpdateSession");
return false;
});
});
function CloseDialog(URL) {
jQuery.support.cors = true;
$.ajax({
type: "GET",
url: URL,
data: '{}',
contentType: "application/json; charset=utf-8",
dataType: "jsonp",
success: function (response) {
alert("success");
},
failure: function (response) {
alert("Failed to trying to find the method: " + URL );
}
});
return false;
}

Try this with pure javascript
function CloseDialog(URL) {
var request = new XMLHttpRequest();
request.open("GET", URL);
request.onload = function() {
if (request.status === 200) {
alert(request.responseText);
// to convert to JSON object-> JSON.parse(request.responseText);
} else {
alert("Failed to trying to find the method: " + URL );
}
};
request.send();
return false;
}
With jQuery I would just do this, you don't need more. It should work with cross-domain too.
function CloseDialog(URL) {
$.ajax({
url: URL,
success: function (response) {
jQuery.each(result.list, function(i, val) {
// iterate the JSON object
// val.node;
});
},
failure: function (response) {
alert("Failed to trying to find the method: " + URL );
}
});
return false;
}
