Can i eliminate empty values using arcade in my pop up?
I am attempting to create a conditional arcade expression that will list all of the fields that do not have a null value with an individual label and not show the field at all if the field is null. My current expression is below.
if (IsEmpty($feature.ABARTA_WI)){
return ""
} else {
return "Abarata: "+$feature.ABARTA_WI
}
This expression works in that it does not show the label or null value, but in the ArcGIS Portal pop up, it leaves an empty line for each one that is null, and i need it to not be there at all so the pop up is clean. As you can see below, this is creating empty lines in the popup.
I would prefer the popup to display something like below, eliminating the empty lines.
Chief: 0.28
Chief WI MKR: 0.28
Enerplus: 0.3

Any help would be greatly appreciated.
Thank you
Using something similar to what you have, you could use an approach like this.
{expression/expr1}
var a = $feature.notes
var b = $feature.popper
var attributes = ""
If (!IsEmpty($feature.notes)){
attributes = a + TextFormatting.NewLine + b
}
else {
attributes = b
}
return attributes
If Feature notes attribute is not Empty Show both attributes.
Else show one attribute

I was looking all over for a solution that I could only display non null field values with the field alias and ended up combining a few different things I found.
var features = FeatureSetByName($map, 'CTP_Roadway_Observations', ['*'], false);
var aDict = Schema(features);
var aArray = aDict["fields"];
var output;
for (var i in $feature){
if (!IsEmpty($feature[i])) {
for(var j in aArray) {
var dict = aArray[j];
if (dict['name'] == i){
output += dict['alias'] + ": " + $feature[i] + TextFormatting.NewLine + TextFormatting.NewLine;
}
}
}
}
return output;
Produces this:
