# HTML DOM onseeking Event
The `onseeking` event occurs when the user starts moving or skipping to a new position in an audio or video file.
This event is triggered as soon as the seeking process begins (e.g., when a user drags the playhead to a new time on the progress bar).
---
## Definition and Usage
The `onseeking` event is fired when a seek operation starts on a media element (`
` or ``).
* **Related Event:** The opposite of the `onseeking` event is the (event-onseeked.asp) event, which fires when the user has finished moving to the new position in the audio/video.
* **Useful Property:** You can use the `currentTime` property of the media element to set or return the current playback position (in seconds).
