title: Trying to detect browser close event
body: <p>I have tried many methods to detect browser close event through jQuery or JavaScript. But, unfortunately, I have not been able to detect the close. The <code>onbeforeunload</code> and <code>onunload</code> methods are also not working.</p>
  
  <p>How do I detect the window <code>close</code>, <code>unload</code>, or <code>beforeunload</code> events?</p>
