Hi,

I am having an issue with getting the height of an iframe's body element through jQuery. It works in Chromium based browsers as intended, but it returns 0 as the height (in bdyheight). I was asked by a Safari developer to post this here. If there is a workaround that is known, please let me know!

Here's the code:

<iframe id="dbframe" src="https://transitiontn.org/assessment-database-vr/" width="100%" scrolling="no" >

<script>
  jQuery("#dbframe").on("load", function() {
  let head = jQuery(this).contents().find("head");
  let css = '<style>#top-header, #main-header, #main-footer{display: none;}#page-container{padding-top: 0!important;}               </style>';
  jQuery(head).append(css);
  let bdyheight = jQuery(this).contents().find("body").height();
  jQuery(this).height(bdyheight);

  let dblinks = jQuery(this).contents().find("td a");
  jQuery(dblinks).click(function() {
    jQuery("html").animate({scrollTop: 0 }, 800);
    window.setTimeout(function(){jQuery("#dbframe").height(2000)}, 2000);   
  });  
  }); 
</script>

Thank you!
