Why triggering second event "onmouseup" is getting error !

Faisal

When i click on the button it is working, but when i release the button second event "onmouseup" is triggered and ajax function is getting error. Is there anything wrong in the script ?

<button id="myP" onmousedown="mouseDown_b()" onmouseup="mouseUp_b()">Click Mebutton>

Here is the code behind of that event
public partial class _Default : System.Web.UI.Page

{



    private static SerialPort ardo;

    protected void Page_Load(object sender, EventArgs e)

    {



        ardo = new SerialPort();

        ardo.PortName = "COM8";

        ardo.BaudRate = 9600;



        if (!Page.IsPostBack)

        {



        }



    }

     [WebMethod, ScriptMethod(ResponseFormat = ResponseFormat.Json, UseHttpGet = false)]

    public static void testMethod_a(string currentState)

    {

        ardo.Open();

        try

        {

            ardo.Write(currentState);

            ardo.Close();

        }

        catch (Exception ex)

        {



            ardo.Close();

        }

    }

}
