I have a jQuery snippet as below:
$.ajax({
  ....
  success: function(myContent) {
    .....
    $(\'\').append         
<script async src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script>
<ins class="adsbygoogle"
     style="display:block"

     data-ad-slot="7305827575"
     data-ad-format="auto"
     data-full-width-responsive="true"></ins>
<script>
     (adsbygoogle = window.adsbygoogle || []).push({});
</script>        </div>

<p>I believe some browsers need a short delay for it to recognize the DOM of a new iframe. Using a timeout should work:</p>

<pre><code>$('<iframe id="myFrame" name="myFrame">').appendTo("body").ready(function(){
    setTimeout(function(){
        $('#myFrame').contents().find('body').append(myContent);
    },50);
});
</code></pre>
    </p>
             <div class="appendcontent">
                                                        </div>
