title: Can I change the viewport meta tag in mobile safari on the fly?
body: <p>I have an AJAX app built for mobile Safari browser that needs to display different types of content.</p>
  
  <p>For some content, I need <code>user-scalable=1</code> and for other ones, I need <code>user-scalable=0</code>.</p>
  
  <p>Is there a way to modify the value of the content attribute without refreshing the page?</p>
  
  <pre><code>&lt;meta name="viewport" content="width=device-width; initial-scale=1.0; maximum-scale=1.0; user-scalable=0;" /&gt;
  </code></pre>
