HTMLMediaElement.readyState
I can never recall the readyState property of the HTMLMediaElement when I need it so here it is as defined by MDN, hopefully it will remain in the brain a little longer now that I have copied it here.
The HTMLMediaElement.readyState property indicates the readiness state of the media. MDN HTMLMediaElement.readyState
| Constant | Value | Description |
|---|---|---|
| HAVE_NOTHING | 0 | No information is available about the media resource. |
| HAVE_METADATA | 1 | Enough of the media resource has been retrieved that the metadata attributes are initialized. Seeking will no longer raise an exception. |
| HAVE_CURRENT_DATA | 2 | Data is available for the current playback position, but not enough to actually play more than one frame. |
| HAVE_FUTURE_DATA | 3 | Data for the current playback position as well as for at least a little bit of time into the future is available (in other words, at least two frames of video, for example). |
| HAVE_ENOUGH_DATA | 4 | Enough data is available—and the download rate is high enough—that the media can be played through to the end without interruption. |
