Default
Description
playbackRate
number
required
The rate to set on click, such as 1.5.
Data attribute
Description
data-active
The current playback rate equals this button’s playbackRate, whether or not the media is playing.
Your onClick runs before the built-in one; call event.preventDefault() in it to skip the built-in behavior.
Media state attributes
Five of these describe loading, and exactly one of them is set at a time. The other three mark features the browser lacks. Use them to hide controls that can’t work, or to style the player while it loads.
Data attribute
Description
data-media-pending
Loading hasn’t started. This is the initial state.
data-media-loading
The media has started loading.
data-media-metadata-loaded
The duration and dimensions are known, but there isn’t enough data to play yet.
data-media-playable
The media can play. It stays set if playback later stalls to buffer.
data-media-error
The media element reported an error, such as a network or decoding failure. A blocked play() call doesn’t set it; use onError for that.
data-fullscreen-unsupported
The browser can’t go fullscreen, or support hasn’t been detected yet.
data-pip-unsupported
Picture-in-picture isn’t available, such as for audio, or support hasn’t been detected yet.
data-volume-change-unsupported
The browser doesn’t let scripts set the volume, such as on iOS, or support hasn’t been detected yet.
