title: How to include CDN in javascript?
body: <p>I know how to include CDN in HTML file. </p>
  
  <pre><code>&lt;!DOCTYPE html&gt;
  &lt;html&gt;
  &lt;head&gt;
  &lt;!-- jQuery library --&gt;
  &lt;script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"&gt;&lt;/script&gt;
  &lt;/head&gt;
  &lt;body&gt;
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>But what I am trying to do is:<br>
  I want to include CDN like jquery in my javascript file.  </p>
  
  <p>May be what I am trying to do is impossible.<br>
  Actually, I want to call <em>BootstrapDialog.Confirm</em> from my javascript file.<br>
  So, I want to include required CDN for BootstrapDialog in js file.<br>
  Then I can call <em>BootstrapDialog.Confirm</em>.</p>
  
  <p>If my question is not reasonable, forgive me as I am a beginner.</p>
