title: Find all elements that DON'T have specific CSS class in jQuery?
body: <p>I have already find a lot of questions like this here in Stack Overflow but none help me.</p>
  
  <p><strong><em>My Elements are added dynamically by Ajax.</em></strong></p>
  
  <p>When I try to find all elements that don't have specific class, it return the element ho has.</p>
  
  <p>Take a look:</p>
  
  <p><img src="https://i.stack.imgur.com/vLpNs.png" alt="enter image description here"></p>
  
  <p>As you can see, it returns the last element, ho has the div with class <code>btn-group</code>.</p>
  
  <p>I want all elements that don't have this div inside.</p>
