The TimeRanges
interface is used to represent a set of time ranges, primarily for the purpose of tracking which portions of media have been buffered when loading it for use by the <audio>
and <video>
elements.
A TimeRanges
object includes one or more ranges of time, each specified by a starting and ending time offset. You reference each time range by using the start()
and end()
methods, passing the index number of the time range you want to retrieve.
