Sorry, I got my variable names wrong and I didn't explain that very well. But
anyway, I figured it out.
You can access the following from any vector layer:
The "fid" with vector_layer.feature.fid, which should look something like
"layer_prefix.layer_name.n", where n is an integer.
The "id" with vector_layer.feature.id, which should look something like
"OpenLayers.Feature.Vector_n", where n is an integer.
My problem was trying to get the "id" so I can use the function
vector_layer.getFeatureById(id). I don't know the "id" in advance, but I can
get the "fid" from a WMS layer.
All I did was have a for-loop that will look for the feature with the
particular "fid" and get the "id" from there:
var feature_id = layer_prefix.layer_name.n; <-- here is the
FID
var layer_features = vector_layer.features;
for (var i=0; i<layer_features.length;i++){
if (layer_features[i].fid==feature_id) {
var layer_id = layer_features[i].id; <--- here is
the ID
return layer_id;
}
}
Now I have another problem, which I posted on a different thread
