In general, an AU request is caused by a widget event (Event) that is going to be sent to the server. It happens when a widget event is targeting a widget that is created at the server, or with the toServer option (specified in Event.opts). In additions, you could invoke Au.fire() explicitly to fire an AU request to the server.
Fire Event to Widget
An event can be fired to a widget by use of Widget.fire(String, Object, Map, int) and Widget.fireX(Event, int). For example,
onCloseClick: function () {
this.fire('onClose');
}
The event will be propagated to the widget's parent, parent's parent and so on, until all ancestors are notified, or the propagation has been stopped by Event.stop(Map).
After the widget and all of its ancestors are notified, this event is converted to an AU request and sent to the server, if
- The widget has a peer component, i.e., the widget was created by ZK Client Engine because of the instantiation of a component at the server.
- Or, the toServer option has been specified in Event.opts of the event.
