body: <p>How to get an event of back browser on mobile safari with state on URL?</p>
  
  <pre><code>ex: domain.com#a -&gt; domain.com#b
  </code></pre>
  
  <p>when I click to back browser <code>domain.com#b -&gt; domain.com#a</code> <br/>
  but it's not triggering any event (<strong>popstate, pageshow, pushstate,</strong> even when I use <strong>setInterval</strong> to check the change of state on the URL)</p>
