TextTrackCue: startTime property
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
The startTime
property of the TextTrackCue
interface returns and sets the start time of the cue.
Value
A number representing the start time, in seconds.
Examples
In the following example a new VTTCue
(which inherits from TextTrackCue
) is created starting at 0.1 second and ending at 0.9 seconds. The startTime
property is then printed to the console.
js
let video = document.querySelector("video");
let track = video.addTextTrack("captions", "Captions", "en");
track.mode = "showing";
let cue1 = new VTTCue(0.1, 0.9, "Hildy!");
console.log(cue1.startTime); // 0.1
track.addCue(cue1);
