control zoom level when using query url parameter

Question

Hi,

I have an app made using web appbuilder developer edition V 2.14

I am using query url parameter to focus on a feature. The query works well, but - the zoom level is too close.

I changed the zoom level inside the "MapUrlParamsHandlerfile" in the jimu.js folder:

query.maxAllowableOffset = 0.00001;
 layer.layerObject.queryFeatures(query).then(function(featureSet){
 var features = featureSet.features;
 if(features.length === 0){
 console.log('No result from query URL parameter.');
 return;
 }
 if(layer.layerObject.geometryType === 'esriGeometryPoint' && features.length === 1){
 map.setExtent(scaleUtils.getExtentForScale(map, 100000));//same scale with search dijit
 map.centerAt(features[0].geometry);
 }else{
 var resultExtent = jimuUtils.graphicsExtent(features);
 map.setExtent(resultExtent);
 }

showSelections(map, layer, features);
 }, function(err){
 console.error(err);
 });
 }

but it does not effect the query result zoom level.

I guess this is not the right place to specify the zoom level I want.

so, where is the right place??

thank you!

Dikla, So is your feature that is queried a point feature? Because the line you have with the red text will only come into effect if the returned feature is a point type. If it is not a point then it will get the features extent in the else portion of the if statement. to control that you need to expand the extent by some factor. }else{ var resultExtent = jimuUtils.graphicsExtent(features); map.setExtent(resultExtent.expand(1.5)) //this means expand the extent by 50%; }‍‍‍‍
