Maribel,
It is possible and I have done it. Here is a snippet of code that I use:
var layerOrder = ['layer1', 'layer2', 'layer3'];
if (layerOrder && layerOrder.length) {
var ignore = false;
on(this.map.infoWindow, 'dfd-complete', function(evt) {
// The dfd-complete event is undocumented and may not work in future versions.
if (evt.target.count > 1) {
evt.target.setContent('');
}
});
on(this.map.infoWindow, 'set-features', function(evt) {
if (ignore || evt.target.count < 2) {
return;
}
var features = evt.target.features;
var layerNames = [];
var newLayerIndexes;
var index;
var newFeatures = [];
array.forEach(features, function(feature) {
layerNames.push(feature.getLayer().name);
});
newLayerIndexes = Array(layerNames.length);
array.forEach(layerNames, function(layerName, idx) {
index = array.indexOf(layerOrder, layerName);
if (index === -1) {
newLayerIndexes.push(idx);
} else {
// In the case of multiple features from the same layer
while (newLayerIndexes[index] !== undefined) {
index++;
}
newLayerIndexes[index] = idx;
}
});
array.forEach(newLayerIndexes, function(index) {
if (index !== undefined) {
newFeatures.push(features[index]);
}
});
ignore = true;
evt.target.setFeatures(newFeatures);
evt.target.show();
ignore = false;
});
}
This code should go into a "headless" widget (like my Anvil Widget). You can see it in action here: Hamilton County Map Viewer. My layerOrder is:
[
"Cemetery",
"School",
"Railroads",
"Interstates and US Highways",
"State Highways",
"Major Roads",
"Minor Roads",
"Parcels",
"Subdivision",
"Corporate Limits",
"Political Township"
]
When I have some time, I'll put this into another variation of the Anvil Widget.
