Each time a JSF component
is created, a corresponding JavaScriptâ„¢
object is also created. You can
access this object through a global JavaScript variable
whose name is the same as the id
attribute
of the tag. For example, the tag:
<jvmf:mapView id="map" [...] />
is rendered as the following JavaScript code:
map = new IlvDiagrammerViewProxy ('map', ...);
map.setServletClass("ilog.views.maps.servlet.IlvFacesMapsServlet");
See the documentation of the
Javaâ„¢
API
(
overview-summary) of each renderer to know which JavaScript proxy
is generated for this component.
You can modify the object locally by using a set of methods
attached to this object. For further information about available JavaScript
objects, see the JavaScript reference documentation of JViews Maps.
The following example defines a button that dynamically
installs a zoom interactor on the view without a server round trip.
Defining a dynamic zoom interactor button
<jvf:panInteractor id="pan"
<jvf:imageButton [...] onclick="map.setInteractor(pan)" />
<jvmf:mapView id="map" [...] />
At rendering time, an
IlvDiagrammerViewProxy JavaScript object
is created, accessible through the JavaScript variable.
Then, since a JavaScript object named pan
has
been created in the same way, you can directly set this interactor
with the setInteractor
method.
Additionally, the behavior of these JavaScript objects
is to keep their state, so that if a submit request is issued, the
state of the object is sent to the server. This behavior makes sure
that the client and the server remain coherent.

see the JavaScript API reference documentation of JViews Maps.
