Hello I am new in the modx. I want to ask how can I check whether the TV element is empty or not. Means whether admin enters in any value in TV element or not because on front end I want to check whether this TV is empty or not.

I also want to ask where to use that code or script which anyone here will share.

Here is my chunk code:

<script>
  var tag = document.createElement('script');
  tag.src = "http://www.youtube.com/player_api";
  var firstScriptTag = document.getElementsByTagName('script')[0];
  firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
  var player;
  function onYouTubePlayerAPIReady() {
	player = new YT.Player('video', {
	  playerVars: { 'autoplay': 1, 'controls': 1,'autohide':1,'wmode':'opaque' },
	  videoId: '[[*video]]',
	  events: {
		'onReady': onPlayerReady}
	});
  }

  function onPlayerReady(event) {
	event.target.mute();
  }
</script>
<div id="video" style="float: left;margin-top: 10px;width:327px !important;height:200px !important;"><iframe width="327" height="200" src="//www.youtube.com/embed/[[*video]]" frameborder="0" allowfullscreen></iframe></div>

I want to check if

[[*video]]

that is my dynamic TV element, is empty. So that above code will not execute.

Please help.

Thanks.

You can use an output modifier:

[[*video:notempty=`yourcode`]]
