Accepted answer
for me it is working. can you put the break point in below line and check the data what have been passed from jquery

[WebMethod]
[ScriptMethod]
public static string SaveData(string title, string songPath)
{
string appPath = @"C:\";
string filePath = appPath + "txtfile.txt";
StreamWriter w;
w = File.CreateText(filePath);
w.WriteLine(title);
w.WriteLine(songPath);
w.Flush();
w.Close();
// Label1.Text = "File created and write successfully!
";
// Label1.Text += filePath;

return null;
}

try like this

var domain = location.host;
var serviceurl = location.protocol + "//" + domain + "/Default2.aspx/SaveData";
$(document).ready(function () {
// Add the page method call as an onclick handler for the div.
$("#getdate").click(function () {
$.ajax({
url: serviceurl,
data: JSON.stringify({ title: 'title', songPath: 'pathhh' }),
dataType: "json",
type: "POST",
contentType: "application/json;charset=utf-8",
success: function (data) {
$('lbltxt').text(data.d);
},
error: function (xmlHttpRequest, textStatus, errorThrown) {
alert(textStatus);
alert(errorThrown);
}
});
});
});

I am not sure weather you have defined the path correctly or not. for testing purpose try like this

[WebMethod]
    public string SaveData(string title, string songPath)
    {
        string appPath =@"C:\";
        string filePath = appPath + "txt.txt";
        StreamWriter w;
        w = File.CreateText(filePath);
        w.WriteLine(title);
        w.WriteLine(songPath);
        w.Flush();
        w.Close();
       // Label1.Text = "File created and write successfully!
";
       // Label1.Text += filePath;

        return null;
    }

        StreamWriter w;
        w = File.CreateText(filePath);
        w.WriteLine(title);
        w.WriteLine(songPath);
        w.Flush();
        w.Close();
       // Label1.Text = "File created and write successfully!
";
       // Label1.Text += filePath;

        return null;
    }

    public string PhysicalApplicationPath { get; set; }

Hi,
You can use Jquery Ajax to pass multiple values, like this

$.ajax({
type: "POST",
contentType: "application/json;charset=utf-8",
url: "SaveAudiVideo.aspx/SaveData",
data: JSON.stringify({title: 'value1' ,songPath: 'value2' }),
dataType: "json",
success: function(data) {
$('lbltxt').text(data.d);
},
error: function(result) {
alert("error");
}
});

[WebMethod]
public static string SaveData(string title,string songPath)
{
string str = string.Empty;
return str;
}
