title: How to debug JavaScript code with Netbeans?
body: <p>I am not experienced in developing web apps with <a href="https://netbeans.org/" rel="nofollow">NetBeans</a>.</p>
  
  <p>I created an HTML5 project with existing sources (some HTML, JS and CSS files), the import seems to be OK, but <strong>I didn't manage to debug JavaScript</strong> code, because the <strong><em>"Debug project"</em>, <em>"Debug file"</em> and <em>"Debug test file"</em> menu items are always disabled</strong>.</p>
  
  <p>What have I missed?</p>
  
  <p><sub>PS.: I downloaded a fresh version in November 2013.</sub></p>
