Event handlers for tabbed panels

Many Faces components have events associated with them. For example, a Command - Button component has events such as onclick and onmousedown associated with it. Using the Quick Edit view for a selected Faces component, you can define actions for specific events.

Once you select an event in the left pane of the Quick Edit view for the component, you can enter JavaScript code in the right pane of the Quick Edit view. This code represents the actions performed when an event is called.

The following table includes events for the tabbed panel component and for the panels in the tabbed panel component.

Event	Description	Supported component
oncancel	Fired when the user clicks Cancel, if it has been enabled. With the event handler for this event, you can add arbitrary business logic, such as clearing values filled in by the user in some input fields. The event object has one property. tabpanelForm - the HTML form, if any, surrounding the tabbed panel .	Tabbed panel
onenter	Fired when a panel in a Tabbed Panel is entered. If the event handler returns true, then the tabbed panel can enter the new panel; otherwise, the focus remains on the previous panel. With the event handler for this event, you can do things such as verify information that the user enters or prepare information displayed in the panel. The event object has one property. tobeEnterPanel - the ID of the panel that is going to be entered.	Panel in a tabbed panel
onexit	Fired when a panel in a Tabbed Panel is exited. The event handler can return three different values, A panel ID, which will be the next entered panel instead of the default next panel. True, the default next panel will be displayed. False or doesn't return anything, the focus remains on the current panel. With the event handler for this event, you can add arbitrary business logic like verifying input by the user and refusing to leave the panel if verification fails or controlling the flow to the next panel. This event handler can be used to create complex flows when the Tabbed Panel is used with the Next and Previous buttons. The event object has one property. tobeExitPanel - the ID of the panel that is going to be entered.	Panel in a tabbed panel
