Hi,
I have a vector layer with some feature data. The layer is not visible at first
(vectorLayer.setVisibility(false)), but made visible when user starts selecting
an option. But I only want certain vector points drawn based on their feature
attributes (i.e. vectorLayer.features.attributes.<data>).
When a user option is selected, I loop through all features (i.e.
vectorLayer.features.length). Set renderIntent to no display (
OpenLayers.Style({display: "none"}) ) for the vector point if its feature
attribute ( vectorLayer.features.attributes.<data> ) does not match user input.
This only works when all the feature data are loaded onto the browser. That is
all features are drawn because I can't enter the loop the first time (length=0)
Does anyone know how to preload those features before the layer is made visible
the first time?
Thanks,
John
