Question

Does anyone know how can I using jquery to retrieve the data from the function in aspx.cs in .net c# web application?

Example:
if I have a function call public void getData(string serachValue). When the user type in the word in the textbox, it will use jquery to call getData() to return the result and show on the screen

First make this function static and add webmethod attribute:

[WebMethod]
 public static string Confirm(int id)
    {
        // confirm entry

        return "Test Data";
    }

Then use ajax() jquery method: http://api.jquery.com/jQuery.ajax/

 $('.confirmBtn').click(function () {
        $.ajax({
            type: "POST",
            url: "MyPageName.aspx/Confirm",
            data: '{"id":"' + 1 + '"}',
            contentType: "application/json; charset=utf-8",
            dataType: "json",
            success: function (data) {
                var returnData = data.d;


            },
            error: function (xhr, ajaxOptions, thrownError) {
                alert(thrownError.toString());
            },
            timeout: function (data) {

            }
        });
    });
