[mono-android] Passing callback functions from Javascript to Mono

[Terry151151]

I have a JQuery script that calls a Javascript interface and I would like to
pass two callback functions to Mono. When the C# function get called from
the WebView the two functions are null. Any idea how to pass the callback
functions?


Simplified Code:


JQuery:

$(document).ready( function()
{
var OkBtn = $( '#OkBtn' );

var DisableOk = function()
                                {
                                        OkBtn.attr( 'disabled', true );
                                };

var EnableOk = function()
                                {
                                        OkBtn.attr( 'disabled', false );
                                };

var HttpAddress = $( '#HttpAddress' );

    HttpAddress.click(function (e)
        {
        window.Device.HttpCheck( HttpAddress.val(), EnableOk, DisableOk );
    });

C#
        public class JavaScriptInterface : Java.Lang.Object
        {
                [Export]
                public Java.Lang.Boolean HttpCheck( Java.Lang.String _url,
Java.Lang.Runnable OnSuccess, Java.Lang.Runnable OnFail )
                {
                        bool Result = false;
                        Java.Lang.Boolean Retval;
        
                        try
                        {
                                string url = _url.ToString();

                                if( Url.IsValidUrl( url ) )
                                {
                                        OnSuccess.Run();         // OnSuccess 
is null
                                        Result = true;
                                }
                                else
                                {
                                        OnFail.Run();              // OnFail is 
null
                                        Result = false;
                                }
                        }
                        finally
                        {
                                Retval = new Java.Lang.Boolean( Result );
                        }
                        return Retval;
                }
       }


Thanks in advance
Terry
