title: Find jQuery code that trigger then event in Web Browser
body: <p>I joined a team to work on a project. Now that they use jQuery and a lot of the javascript file are external files instead of embedded.</p>
  
  <p>When I clicked a button, which simply looks like:</p>
  
  <pre><code>&lt;a class="button_cancel"&gt;Cancel&lt;/a&gt;
  </code></pre>
  
  <p>It trigger an event which is defined in one javascript file.</p>
  
  <p>Is there a way to locate the file (or even the exact line of the file) when the onclick is triggered?</p>
