I'm trying to label address points (with the ArcGIS Online labeling functionality) for one of our city's webmaps. Some of the addresses have unit numbers, some don't. I put together an Arcade expression that checks the "unit" field for values so that all points will be labeled correctly.

var unitVal = $feature.unit
var stVal = $feature.snumber
function mainfunc(unitVal,stVal){
  if (unitVal == ' '){
      return stVal
  }
  else {
      return Concatenate([stVal,unitVal], ':')
  }
}

mainfunc(unitVal,stVal);‍‍‍‍‍‍‍‍‍‍‍‍‍

The labels appear correctly in ArcGIS Online, but will not draw in a web application that calls on that AGO map. Has anyone come across the same issue?

Michael,

     Have you tried adding semicolons at the end of your first two lines?

Hi Rod,

Just tried that, and no change, unfortunately.

Thanks for looking into it

I'm looking into this as well... will reply if I learn anything.

FYI, the expression could also be condensed to the following (but it doesn't really matter. Depends on your preference):

var unitVal = $feature.unit;
var stVal = $feature.snumber;
IIF(unitVal == ' ', stVal, Concatenate([stVal,unitVal], ':'));

Which version of the JS API are you using, 4.x or 3.x? Labeling isn't supported in 4.x yet. I was able to verify this in a 4.x app, but noticed the expected behavior in 3.x...
