Example
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.
