title: How to debug in the application.js with compressed javascript
body: <p>I got the following errors,</p>
  
  <p>When I opened the Chrome javascript console,then look insight it.</p>
  
  <p><code>application.js?body=1:1249</code></p>
  
  <p>It is just  a group of compressed js code</p>
  
  <p>And I've open the in the <code>development.rb</code></p>
  
  <pre><code>  # Expands the lines which load the assets
    config.assets.debug = true
  </code></pre>
  
  <p>I can not grep the any piece of the javascript source code in my Rails app.</p>
  
  <p>So I don't know where does it come from ?</p>
  
  <p>How can I fix the unknown error quickly in Rails ?</p>
  
  <p>Thanks </p>
