title: How to trigger MathJax?
body: <p>I included <code>MathJax</code> with the script</p>
  
  <pre><code>&lt;script type="text/javascript" async
    src="https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.1/MathJax.js?config=TeX-MML-AM_CHTML"&gt;
  &lt;/script&gt;
  </code></pre>
  
  <p>This automatically replaces all math codes with the formatted tags.</p>
  
  <ol>
  <li>How can I trigger <code>MathJax</code> by a javascript click only, instead of upon load.</li>
  <li>How can I tell <code>MathJax</code> to put the formatted element at the end of the page instead of replacing the original code?</li>
  </ol>
