I want to check for ANY element on the page where the id has no value, and then remove them using jQuery's
remove()
<iframe id class="iframeCol"...></iframe>
<div id class="sectional">..</div>
You can use the attribute selector to achieve this:
$('[id=""]').remove();
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<iframe id class="iframeCol">Remove this</iframe>
<div id class="sectional">And remove this</div>
<div>Keep this</div>
<div id="foo">And this</div>
