Hi,
mySubmitButton.add(AttributeAppender.append("onclick", "window.dontAsk =
true; return true;"))
response.render(new
OnDomReadyHeaderItem("window.onbeforeunload = function (e) {"
+ "if (!window.dontAsk) {" +
+ "var message = 'Your confirmation message goes
here.',"
+ "e = e || window.event;" + "if (e) {"
+ "e.returnValue = message;" + "}" + "return message;"
+ "}"
+ "};"));
