<pre style='color:#555'>> @@ -36,6 +36,9 @@ OSM.Directions = function (map) {
     OSM.DirectionsEndpoint(map, $("input[name='route_to']"), OSM.MARKER_RED, endpointDragCallback, endpointChangeCallback)

<p dir="auto">Well, this doesn't need to be done for every route displayed, so I want it to be outside of a function. For the download URL, I want to be able to revoke the last blob URL when creating the new one.<br>
For now, I could drop the marker-color assignment or just export the polyline, as the pages linked in <a class="issue-link js-issue-link" data-error-text="Failed to load title" data-id="2535832941" data-permission-text="Title is private" data-url="https://github.com/openstreetmap/openstreetmap-website/issues/5224" data-hovercard-type="issue" data-hovercard-url="/openstreetmap/openstreetmap-website/issues/5224/hovercard?comment_id=2362118967&comment_type=issue_comment" href="https://github.com/openstreetmap/openstreetmap-website/issues/5224#issuecomment-2362118967">#5224 (comment)</a> do.</p>
