TimeRanges.length

The TimeRanges.length read-only property returns the number of ranges in the object.

SyntaxEdit

length = TimeRanges.length;

ExampleEdit

Given a video element with the ID "myVideo":

var v = document.GetElementById("myVideo");

var buf = v.buffered;

var numRanges = buf.length;

if (buf.length == 1) {
  // only one range
  if (buf.start(0) == 0 && buf.end(0) == v.duration) {
    // The one range starts at the beginning and ends at
    // the end of the video, so the whole thing is loaded
  }
}

This example looks at the time ranges and looks to see if the entire video has been loaded. Obviously you could simply observe the ended event on the video, but this is a good example of how TimeRanges works.
