Web Map Popup - Display URL Hyperlink if Exists?

ArthurSmith2 — Mon, 10 Aug 2026 15:13:45 GMT

Hello Esri Community! I am looking for help with a seemingly simple task: within a popup text element, I want to display a clickable hyperlink for a record if it exists.

The closest I have come is using this Arcade expression and text element configuration... however the 'View Link' text shows as un-clickable link if URL not populated; not ideal.

I want the 'View Link' clickable text to only show if link present. Can someone explain how this can be accomplished? Thanks in advance!

// Reference your attribute field containing the URL

var myUrl = $feature.ASBUILTS;

// Check if the field is empty or null

if (IsEmpty(myUrl) || Trim(myUrl) == "") {

return ""; // Return nothing if it doesn't exist

} else {

// Return a formatted HTML link if it does exist

//return '<a href="' + myUrl + '" target="_blank" rel="noopener noreferrer">Visit Website</a>';

return myUrl;

}

@ArthurSmith2

Here is one idea for your expression. It should return a URL is if exists, and if it doesn't, nothing will be returned.

var myUrl = Trim(DefaultValue($feature.ASBUILTS, ""));

if (IsEmpty(myUrl)) {
return "";
}

return '<a href="' + myUrl + '" target="_blank" rel="noopener noreferrer">View Link</a>';

Hi Jon, thanks for your response!

I tried using your Arcade code and unfortunately the Map Viewer isn't rendering as an html link and instead shows the plain text html:

Any ideas to resolve?

@ArthurSmith2 I'm not sure to be honest - at first I thought this would work but now thinking about it, I don't think there's a way to get the hyperlink text to disappear in the popup when there's nothing to open. It may be a limit of using the text as a hyperlink.

You have to add that code in an Arcade element for the html link to work properly. The code would look something like this (which also uses template literals)
