                    button.onclick = function() {
                        var code = "self." + method + "();";
                        alert(code);
                        eval(code);
                    }
                    iframeBar.appendChild(button);                
                }

А так какую бы "кнопку" не нажал выскакивает "self.setUnderline();"
