I use a vector layer that gets data from the server in geojson format.
I create the layer like the following.
Up to now I used only 2 fixed params. Now I would like to use a third
one, dynamic. On the page there'll be a ckeck and I'd like the 3rd
parameter to send to the server also this one.
var p3layer = new OpenLayers.Layer.Vector("mylayer",
{
strategies: [strategy1, strategy2],
protocol: new OpenLayers.Protocol.HTTP({
url: path,
params: {
'l1': 'myparameter',
'id': 'another parameter',
'adb': ???
},
format: new OpenLayers.Format.GeoJSON()
}),
and so on
I tried using a function like the following but it didn't work:
function getadb()
{
return something;
}
var p3layer = new OpenLayers.Layer.Vector("mylayer",
{
...
params: {
'l1': 'myparameter',
'id': 'another parameter',
'adb': getadb()
},
What is the correct way to get what I want?
Thank you
maxx
