body: <p>I've found similar questions here but nothing works for me.</p>
  
  <p>have inputs like:</p>
  
  <pre><code>&lt;input type="text" value="2" name="pages_title[1]"&gt;
  &lt;input type="text" value="1" name="pages_title[2]"&gt;
  </code></pre>
  
  <p>trying to get these fields like:</p>
  
  <pre><code>$('input[name="pages_title[]"]')
  </code></pre>
  
  <p>but have empty results :(</p>
