类名称：Zone

Zone介绍

[英]A Zone is portion of the output page designed for easy dynamic updating via Ajax or other client-side effects. A Zone renders out as a <div> element (or whatever is specified in the template) and may have content initially, or may only get its content as a result of client side activity. When a user clicks an org.apache.tapestry5.corelib.components.ActionLink whose zone parameter is set triggers a series of client-side behaviors, and an Ajax request to the server. The server side event handler can return a org.apache.tapestry5.Block or a component to render as the new content on the client side. Often, re-rendering the Zone's #getBody() is useful. Multiple client-side zones may be updated via the org.apache.tapestry5.services.ajax.AjaxResponseRenderer service. You will often want to specify the id parameter of the Zone, in addition to its Tapestry component id; this "locks down" the client-side id, so the same value is used even in later partial renders of the page (essential if the Zone is nested inside another Zone). When you specify the client-side id, it is used exactly as provided (meaning that you are responsible for ensuring that there will not be an id conflict even in the face of multiple partial renders of the page). Failure to provide an explicit id results in a new, and non-predictable, id being generated for each partial render, which will often result in client-side failures to locate the element to update when the Zone is triggered. In some cases, you may want to know (on the server side) the client id of the zone that was updated; this is passed as part of the Ajax request, as the QueryParameterConstants#ZONE_ID parameter. An example use of this would be to provide new content into a Zone that updates the same Zone, when the Zone's client-side id is dynamically allocated (rather than statically defined). In most cases, however, the programmer is responsible for assigning a specific client-side id, via the id parameter. A Zone starts and stops a Heartbeat when it renders (both normally, and when re-rendering). After the client-side content is updated, a client-side event is fired on the zone's element. The constant core/events:zone.didUpdate can be used to listen to the event.
