Safari iOS not loading Javascript file?
<p>I have just upgraded my iOS because of the recent <a href="http://qz.com/738214/update-your-apple-devices-now-to-fix-a-terrifying-security-bug/" rel="noreferrer">security bug</a>, and I find that my website is no longer loading properly on my phone!</p>

<p>I've boiled the problem down to a simplified example...</p>

<p>index.html =</p>

<pre><code>&lt;html&gt;
&lt;head&gt;
    &lt;title&gt;Demo&lt;/title&gt;
    &lt;meta name="description" content="Test of basic Javascipt function"&gt;
    &lt;script src="demo.js"&gt;&lt;/script&gt;
&lt;/head&gt;
&lt;body class="body"&gt;
    &lt;div id="main"&gt;
    &lt;/div&gt;
&lt;/body&gt;
&lt;/html&gt;
</code></pre>

<p>demo.js =</p>

<pre><code>var i = 0;

function update() {
    'use strict';
    document.getElementById("main").innerHTML = i;
    i = i + 1;
}
setInterval(update, 1000);
</code></pre>

<p>On my desktop this produces an iterating count, but when viewed with Safari on my phone (Mobile/12G34 Safari/601.1) the javascript file simply does not load????  The Javascript file doesn't even show up under the "All Resources" tab in my WebInspector which I am tethering via USB.</p>

<p>Suggestions?</p>

<p>Thanks,</p>

<p>Bill</p>

<p>Edit:
This question has gotten no response, but I'm still wrestling with this problem.  I've found some more information.</p>

<p>Using the Safari WebInspector I've found that the javascript is not loading because...</p>

<blockquote>
  <p>Blocked script execution in '<a href="http://192.168.133.1/demo.html" rel="noreferrer">http://192.168.133.1/demo.html</a>' because
  the document's frame is sandboxed and the 'allow-scripts' permission
  is not set.</p>
</blockquote>

<p>Since I'm serving this page off a homespun webserver on an esp8266, this message has inspired me to tune up my HTTP headers.  The HTTP headers appear to be fine.  </p>

<p>I can't figure out how this html page is getting sandboxed in the first place, and how to 'allow-scripts' so that I can run my script in Safari Mobile.</p>

<p>Any help would be much appreciated.</p>
