<p>If you want to set an html content containg script tag to iframe, you have access to the iframe you created with:</p>

<pre><code>$(iframeElement).contentWindow.document
</code></pre>

<p>so you can set innerHTML of any element in this.</p>

<p><em>But</em>, for script tag, you should create and append an script tag, like this:</p>

<p>You want to be using the iframe's <code>srcdoc</code> attribute for that (MDN documentation).</p>
<pre><code>var html_string = &quot;&lt;html&gt;&lt;body&gt;&lt;h1&gt;My epic iframe&lt;/p&gt;&lt;/body&gt;&lt;/html&gt;&quot;;
document.querySelector('iframe').srcdoc = html_string;
</code></pre>
<p>The nice thing about using this method over for example Red's method listed on this page, is that iframe contents added with <code>srcdoc</code> are seen as the same-origin. That way can continue to manipulate and access the iframe with JavaScript if you wish.</p>
