title: Load external javascript file after onload()
body: <p>I use this in the <code>head</code> tag:</p>
  
  <pre><code>&lt;script src="js/lightbox.js"&gt;&lt;/script&gt;
  </code></pre>
  
  <p>Is it possible to remove this off the header and load this file with <code>onload()</code>?</p>
  
  <pre><code>&lt;body onload="..."&gt;...&lt;/body&gt;
  </code></pre>
  
  <p>Note: This is not a function, it's an external js file with several functions.</p>
  
  <p>Thanks!</p>
