Render fulfillment container only when applicable by jazairi · Pull Request #402 · MITLibraries/timdex-ui

jazairi · 2026-06-04T16:27:23Z

Why these changes are being introduced:

The fulfillment link container currently renders
as an empty div when no links are available. This
pollutes the DOM and affects spacing.

Relevant ticket(s):

USE-611

How this addresses that need:

Primo link removal moves further up in the control
flow, because that check is not applicable if the
parent element is gone.

Side effects of this change:

None.

Copilot

Pull request overview

This PR updates the Stimulus content-loader controller to avoid leaving empty fulfillment/link containers in the DOM when the fetched HTML response contains no meaningful content, reducing DOM pollution and preventing unintended spacing/layout artifacts in results.

Changes:

If the fetched HTML is empty/whitespace-only, remove the loader element instead of replacing it with empty output.
Preserve existing behavior that removes .primo-link elements when a .libkey-link is present.

The change Copilot is suggesting is what I originally had. It would override the existing code in this helper method, which was suggested in a prior Copilot review. 🙃

djanelle-mit

Final edit: I still see the result-get divs on the PR build. There was a couple cases where they were gone but I can't reproduce them now.

JPrevost

This doesn't seem to work. I still see the empty divs in Dave's example from the ticket. I suspect we are injecting them for records we never do lookups so this swap logic never comes into play. The issue may be we need to conditionally inject the divs to begin with (and still clean them up if they result in empty divs)?

It's quite early though so I'm marking this as comment and not request changes because I may not be understanding what is going on :)

+    do {
+      previous = output
+      output = output.replace(/<!--[\s\S]*?-->/g, '')


Are there actually HTML comments we need to strip? I see whitespace, but that's handled by the trim without this new method.
