I found the example to zoom to an Apollo feature, which looks like:

function finish(response) {
 response.results[0].zoom(callback);
}

function example() {
 $GP.search({
 searchType: "apollo",
 keywords: "Cherokee"
 }, finish)
}

I want to do something similar on a WMPS feature, like this:

function finish(response) {
	response.featureId.zoom(callback);
}

function select() {
    $GP.selectedFeatures.add({
        featureId: featureId,
        featureClassId: featureClassId
    }, finish);
}

but I get the error:

         response.featureId.zoom is not a function

Is there another way of zooming to a WMPS feature?

Thanks.

Hi Jason,

Yes, it looks like this method is not populated in the SDK. The selectedFeatures returns Feature object offering those methods (functions):

• center
• get_featureClassId
• get_GeoJSON
• get_id

To zoom to this feature, I would:

1. Use get_GeoJSON
2. Calculcate BBOX of this GeoJSON, for instance using this free JS library https://github.com/geosquare/geojson-bbox
3. If needed, transform the coordinates to the map CRS
4. Use $GP.map.zoom with the bbox parameter

Regards,

Jan
