title: Run Script after slick slider loads
body: <p>I want to add class on body tag after the slick slider loads and after one of the slider has class .class-slide.</p>
  
  <p>HTML</p>
  
  <pre><code> &lt;div class="slider"&gt;
    &lt;div class="slide"&gt;
      1
    &lt;/div&gt;
    &lt;div class="slide"&gt;
      2
    &lt;/div&gt;
    &lt;div class="slide class-slide"&gt;
      3
    &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>So after the slick has loaded and if the slide with class .class-slide is active then i need a demo class on tag.</p>
  
  <p>I tried this</p>
  
  <pre><code>jQuery(function () {
   if(jQuery(".class-slide").hasClass("slick-active")){
     jQuery(body).addClass('body-class');
   }
  </code></pre>
  
  <p>but since the DOM is already loaded this wont work . How can we fix this ?</p>
