jQuery plugin isInViewport

Hello Experts,

I am suing the jQuery plugin isInViewport  from isInViewport
While in view it is playing the videos on the page.

My question:
I am trying to find the way to to play the video while inView when scrolling down the page and not when again when scrolling up. So on up just do nothing or pause the video.

$(window).bind('scroll',function() {

var $video = $("video");

$video.each(function() {  
   if ( $video.is( ':in-viewport')) {
      $(this)[0].play();
   } else {
      $(this)[0].pause();
   }   
});

Open in new window

You don't need the index when inside .each - this refers to the current element in the array. Play and Pause are methods on the control - so you don't need to wrap this in a jQuery object to access them.
Try this.
$video.each(function() {  
   if ( $video.is( ':in-viewport')) {
      this.play();
   } else {
      this.pause();
   }   
});

Correction
$video.each(function() {  
   if ( $(this).is( ':in-viewport')) {
      this.play();
   } else {
      this.pause();
   }   
});

Hello Julian
Thank you for seeing that!
Can you help me resolve this question?
How to execute this only when scrolling down and not when scrolling up?
When the videos already got played (after scrolling down) don;t play it again when scrolling up.

Julian you are a magic :-) Thank you so much!

P.S. "pauseVideo" does not work only "pause" works.

oops - editing mistake - should be pause() - I was heading down a different path and did not go back and undo.

Glad it is working for you.
