wow.js happens only when scroll down once

Question

I'm using wow.js, and it works only on page load and one time when scroll, I would like it to trigger each time when I scroll to the div position and not only once when page is load.

 <div class="wow rotateIn animated" data-wow-delay="0.3s" data-wow-duration="0.5s"></div>

Answer 1

Try this

// Repeat demo content
  var $body = $('body');
  var $box = $('.box');
  for (var i = 0; i < 20; i++) {
    $box.clone().appendTo($body);
  }

  // Helper function for add element box list in WOW
  WOW.prototype.addBox = function(element) {
    this.boxes.push(element);
  };

  // Init WOW.js and get instance
  var wow = new WOW();
  wow.init();

  // Attach scrollSpy to .wow elements for detect view exit events,
  // then reset elements and add again for animation
  $('.wow').on('scrollSpy:exit', function() {
    $(this).css({
      'visibility': 'hidden',
      'animation-name': 'none'
    }).removeClass('animated');
    wow.addBox(this);
  }).scrollSpy();

.box {
  display: block;
  width: 200px;
  background: rgba(255, 255, 255, 0.7);
  color: #eb3980;
  font-family: "Comic Sans MS", "Comic Sans";
  border: 3px dashed pink;
  margin: 30px auto;
  text-align: center;
}

.doge {
  display: block;
  width: 200px;
  height: 200px;
  position: fixed;
  bottom: 10px;
  right: 10px;
  background: url(http://mynameismatthieu.com/WOW/img/wow-8.gif) no-repeat;
}

body {
  background: url(http://mynameismatthieu.com/WOW/img/wow-logo.jpg) #fff fixed no-repeat center center;
}
