            .bind('message', $.websocketSettings.message)
            .bind('message', function(e){
                var m = $.evalJSON(e.originalEvent.data);
                var h = $.websocketSettings.events[m.type];
                if (h) h.call(this, m);
            });
        ws._send = ws.send;
        ws.send = function(type, data) {
            var m = {command: type};
            m = $.extend(true, m, $.extend(true, {}, $.websocketSettings.options, m));
            if (data) m['data'] = data;
            try{ 
                this._send($.toJSON(m));
                } 
            catch(ex)
            { 
                alert(ex);
                return false;   
            }
            return true;
        }
        $(window).unload(function(){ ws.close(); ws = null });
        return ws;
    }
});
})(jQuery);

No one wants the exception to be displayed through an alert box.

You may want to add try/catch when you use the high-level "send" function in 
your own code.
