<viewer-frame mode="refresh-top" auto-refresh-interval="30"> <!-- content --> </viewer-frame> The phrase "viewerframe mode refresh top" is more than a search keyword—it is a specification for predictable, user-respecting UI behavior. By explicitly setting a mode where refreshes reset the viewport to the top, you trade a tiny amount of user scroll effort for massive gains in data consistency and interface clarity.
return ( <div className="viewerframe" ref=frameRef mode=mode> /* Content */ <button onClick=refreshAndGoTop>Refresh Top</button> </div> ); viewerframe mode refresh top
function Viewerframe( data ) const frameRef = useRef(null); const refreshAndGoTop = () => // 1. Refetch data refetchData(); // 2. Force mode to "refresh" setMode('refreshing'); // 3. After DOM update, scroll frame to top setTimeout(() => if (frameRef.current) frameRef.current.scrollTop = 0; // The "top" command Refetch data refetchData(); // 2
.viewerframe overflow-y: auto; scroll-anchoring: none; /* Disable browser's default anchoring */ We will use vanilla JavaScript for clarity
Let's build a functional "viewerframe mode refresh top" widget from scratch. We will use vanilla JavaScript for clarity. Step 1: Define the HTML Structure <div id="app"> <div class="controls"> <button id="refreshBtn">⟳ Refresh & Go to Top</button> <span id="modeIndicator">Mode: View</span> </div> <div id="viewerframe" class="viewerframe"> <!-- Dynamic content will load here --> </div> </div> Step 2: CSS for Stable Viewerframe .viewerframe width: 100%; height: 500px; overflow-y: auto; border: 1px solid #ccc; scroll-behavior: smooth; /* For pleasant top reset */
setMode('view'); , 0); ;
