Question

I have a <video> element that is generated by js, and I need to get the height and width of it.

var v = $('video'); v.height() returns null, because when it’s run, the video hasn’t yet been loaded, so no dimensions in the DOM.

How do I check to see if the video has received a dimension, and if it hasn’t, wait till it has to get the height and width.

Thanks.

Edit:

I’ve created a jsbin with my example code:

Thanks.

Edit: whoops, made an error in the sample code.

Update based on new code – You can use the loadedmetadata event for this, I’ve updated your jsbin example here with this

$('input').click(function () {
  $('#thumbnail video').clone().bind('loadedmetadata', function() {
    alert($('#viewing-area video').height());
  }).appendTo('#viewing-area');
});
