[Edit APRIL 2, 2014]
I want to emphasize something. My scenario does not have a user event driving it to trigger an event listener. I know the Maps API documentation shows how to get a feature's featureId
property from a MapsEngineMouseEvent
. But my scenario needs to get the feature's featureId
programmatically.
I've also tried programmatically "faking" a click, but that doesn't work either. (It seems the event object can't be instantiated??)
My hunch is, the solution to this either 1) doesn't exist, 2) is deceptively simple, or 3) will only be discovered if a minimum level 8 mage rolls a natural 20 wisdom check..
[Original Problem Statement]
I have few scenarios in a customized Google Maps client where I need to loop over features in a DynamicMapsEngineLayer
and modify their style traits. The DynamicMapsEngineLayer
works by performing..
..client-side rendering of vector data, allowing the developer to
dynamically restyle the vector layer in response to user interactions
like hover and click.
The Maps API documentation describes how to restyle individual features using event listeners, which expose a special featureId
value assigned by Google servers. But my scenario doesn't have user-driven events. For example, consider this hypothetical link:
http://www.acme-map.com/index.php?ZoomToAndHighlightFeatureWithId=12345
FeatureWithId
is our own unique id, not Google's special
featureId
, which we don't have at this point in the runtime.
I need the map to load right above a feature and highlight it by changing its style trait. It needs to do this programmatically when the map first loads, without any user interaction. If these vector features are truly rendered in the DOM, then surely there's a way, no matter how cryptic, to reach into the map's guts and access these objects?
Is there a way to loop over individual features in a DynamicMapsEngineLayer or get the featureId property without an event listener?
