HTML seeking DOM Event: Reference and Examples

When someone interacts with a webpage, the browser sends events to the relevant JavaScript code. The seeking event happens when media playback position starts changing.

When seeking happens

Media playback position starts changing.

You can listen for it using addEventListener(). That keeps event handling separate from HTML attributes such as onclick and works well with modern code organization.

A small working example

<video id="demo-target" controls preload="metadata" width="320">
    <source src="sample-video.mp4" type="video/mp4">
</video>
<p id="event-status" role="status">Waiting for seeking...</p>
<script>
    const eventTarget = document.getElementById("demo-target");
    const eventStatus = document.getElementById("event-status");

    if (eventTarget) {
        eventTarget.addEventListener("seeking", (eventDetails) => {
            eventStatus.textContent = "seeking event received";
            console.log(eventDetails.type, eventDetails.target);
        });
    }
</script>

Reading the code

The browser listens for seeking on the relevant target. When the event occurs, the callback receives eventDetails, updates the status message and logs the event name and target in Developer Tools.

Move the media playhead to a new position.

To test this example, put a real supported media file at the shown path. Events tied to buffering or download behavior may not fire in the same order on every connection. An unavailable sample file is not proof that your event listener is broken.

Try it in your browser

Open the page, show the Console panel, and follow this test: Move the media playhead to a new position. Then change one thing in the example and observe whether the event still fires.

Common Beginner Mistakes

• Expecting seeking to fire without its required user action or browser condition.
• Move the media playhead to a new position.
• Adding repeated event listeners without considering cleanup or unwanted side effects.

Key Takeaways

• seeking reports media playback position starts changing.
• addEventListener("seeking", ...) listens for the event on the appropriate target.
• Move the media playhead to a new position.
