Not working for me.. I have a shortcode that outputs a link along with a div container that is hidden with CSS and called when the link is clicked (as a modal). The div container, being a block element, causes the shortcode to end the paragraph early, show the div and then just has the remaining text sort of floating there unwrapped by anything.

So... let's say I have something like this in the tinymce:
Blah blah blah [popup id=5 text="click me to open the popup this should be inline with this blah blah paragraph"] and then the sentence continues.

The HTML output ends up being:

<p>Blah blah blah   </p>
<div id="popup-5" class="popup-modal">click me to open... paragraph</div>
and then the sentence continues.

Was hoping your function would get me output that looked like:
<p>Blah blah blah <div id="popup-5" class="popup-modal">click me to open... paragraph</div> and then the sentence continues.</p>

Any ideas? Thank you!

Wanted to chime in to say 'thank you' for this gist. I was finally fed up with a crappy theme I'm using that aggressively added empty tags every time you hit save on a page. (Going to be moving away from the theme in the future, but gotta get through the next 2 months first). This is/was a life saver.

Adding this jQuery works perfectly fine for me

$('p').each(function() { const $this = $(this); if($this.html().replace(/\s|&nbsp;/g, '').length === 0) $this. Remove(); });

If the p tag is completely empty without space or &nbsp, then this should work
$( 'p:empty' ).remove();
