I have one user control.
In that, I am using Ajax post method, but when I am accessing the same user control in my aspx page, it don't get URL parameter and gives me error 'undefined'.
My code is as below:

JavaScript

function GetRecords(index) {
    //alert(index);

    pageIndex = index;

    $("#loader").show();
    $.ajax({
        type: "POST",
        url: "Customer.ascx/GetCustomers",
        data: '{pageIndex: ' + pageIndex + '}',
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        success: OnSuccess,
        failure: function (response) {
            alert(response.d);
        },
        error: function (response) {
            alert(response.d);
        }
    });
}

C#

[WebMethod]
public static string GetCustomers(int pageIndex)
{       
    return GetCustomersData(min, max, pageIndex).GetXml();
}

Check if the URL Customer.ascx/GetCustomers is correct or not?

Hi,

This ajax call that you are making, is it existing on the ascx control or some separate file.

one thing i recognized is that, the path that you are giving here, should be complete path from

root directory or use a '~' operator. so that there will be no problem with the path.

The thing with the paths is when they were placed in the control and this control is referenced

in an other page. the path is not tracked properly.

so, you can try one of the two approaches (if the path is a problem)

use :

1) var originalPath="<your_site_url_>+ <webservices_directory>"

now you can call like" Url:originalPath+"<webmethod_needed>"

2) try to put a '~' operator. and set path to webservices directory.

Hope this helps.

you should always try to implement the ajax calls in a separate file so that you can debug

and see y they fail.

Happy coding..
