How to use JQuery to show the Primefaces’s confirmDialog ?

Answer 1

The Primefaces dialogs have javascript convenience methods for showing and hiding.

// where dialog is the widgetVar of your Primefaces dialog.
dialog.show();
dialog.hide();

For many of the Primefaces components however you can access the underlying jQuery object by looking for a property jq.

component.jq.removeClass('exampleClass');

Above is an example.
