The Video seekable property is used for returning a TimeRanges object. The TimeRanges object is used for representing the ranges of the video which are available for seeking by the user. 
The time-range of video which is available for seeking i.e. moving playback position is called a seekable range. 
It is often possible to seek anywhere in the video even before it has been buffered if its a non-streaming video. 
The Video seekable property is a read-only property.
The time ranges of object properties are: 
 

  • length: It is used to get the number of played ranges in the video
  • start(index): It is used to get the start position of a played range
  • end(index): it is used to get the end position of a played range


Syntax:

videoObject.seekable


Below program illustrates the Video seekable property.
