試一試 - JavaScript Reference onseeked

In this example, we attach a "seeked" event to the video element. The currentTime property returns the current position (in seconds) of the video playback.

Move to a new position in the video.

<video id="myVideo" controls>
 <source src="mov_bbb.mp4" type="video/mp4">
 <source src="mov_bbb.ogg" type="video/ogg">
 Your browser does not support HTML5 video.
</video>

Seeked to position:

// Attach a seeked event to the video element, and execute a function if a seek operation completes
x.addEventListener("seeked", myFunction);

function myFunction() {
 // Display the current position of the video in a p element with id="demo"
 document.getElementById("demo").innerHTML = x.currentTime;
}
</script>
