The read-only HTMLMediaElement
property duration indicates the length of the element's
media in seconds.
Syntax
myDuration = htmlMediaElement.durationValue
A double-precision floating-point value indicating the duration of the media in
seconds. If no media data is available, the value NaN is returned. If the
element's media doesn't have a known duration—such as for live media streams—the value
of duration is +Infinity.
Examples
var obj = document.createElement('video');
console.log(obj.duration); // NaN
