Pop-up: Link to URL with Link text; if empty return text No As-Built Document text

GeoWorld13 — Thu, 02 Apr 2026 16:50:32 GMT

Hello - I would like to create a dynamic pop-up that links out to an As-Built document related to a feature. However, some features do not have any As-Builts and have empty values in the data. If that is the case, I want the pop-up to read: There is no As-Built Plan for this project.

What I have so far is an attribute expression:

if (IsEmpty($feature.Orignal_Project_PDF)) {

return "There is no As-Built Plan for this project.";

} else {

return '<a href="' + $feature.Orignal_Project_PDF + '" target="_blank">Link</a>';

}

Pop-up HTML:

📄 As-Built Plans: 
{expression/expr4}

How ever my pop-up looks like this:

See anything I am doing wrong?

This gets you closer, however it formats the static text as a link as well...

The expression:

if (IsEmpty($feature.Orignal_Project_PDF)) {

return "There is no As-Built Plan for this project.";

} else {

return $feature.Orignal_Project_PDF;

}

Then to add that in the popup add text and insert your expression as a link and put in your expression name.

HTML:

As-Built Plans: 
<a href="{expression/expr0}">{expression/expr0}</a>

@GeoWorld13

I just revisted and think I got it to work, instead of an expression and a text popup, just add an Arcade item and do all of it there:

add this code:

var nolink = "There is no As-Built Plan for this project." var url1 = $feature.Orignal_Project_PDF var base = "" if (IsEmpty($feature.Orignal_Project_PDF)) { var base = nolink; } else { var base = '<a href='+url1+' target="_blank">Link</a>'; } return { type : 'text', text : "As-Built Plans: "+base+"" }
