Implementing a full page animated loader

I have created a ripple full page loader. I'm trying to create the one like here. I want the code to be simple with no plugins ideally. I can load the page preloader but am wondering how I get the loading page to disappear once the main page has loaded? The page just will not fade! Have researched and tried all sorts of methods. This is the code so far:

// Page loading animation
$(window).on('load', function() {
  if ($('.cover').length) {
    $('.cover').parallax({
      imageSrc: $('.cover').data('image'),
      zIndex: '1'
    });
  }

  $("#preloader").animate({
    'opacity': '0'
  }, 600, function() {
    setTimeout(function() {
      $("#preloader").css("visibility", "hidden").fadeOut();
    }, 300);
  });
});
#preloader {
  overflow: hidden;
  background-color: #fb5849;
  left: 0;
  right: 0;
  top: 0;
  bottom: 0;
  position: fixed;
  z-index: 99999;
  color: #fff;
}

#preloader .jumper {
  left: 0;
  top: 0;
  right: 0;
  bottom: 0;
  display: block;
  position: absolute;
  margin: auto;
  width: 50px;
  height: 50px;
}

#preloader .jumper>div {
  background-color: #fff;
  width: 10px;
  height: 10px;
  border-radius: 100%;
  -webkit-animation-fill-mode: both;
  animation-fill-mode: both;
  position: absolute;
  opacity: 0;
  width: 50px;
  height: 50px;
  -webkit-animation: jumper 1s 0s linear infinite;
  animation: jumper 1s 0s linear infinite;
}

#preloader .jumper>div:nth-child(2) {
  -webkit-animation-delay: 0.33333s;
  animation-delay: 0.33333s;
}

#preloader .jumper>div:nth-child(3) {
  -webkit-animation-delay: 0.66666s;
  animation-delay: 0.66666s;
}

@-webkit-keyframes jumper {
  0% {
    opacity: 0;
    -webkit-transform: scale(0);
    transform: scale(0);
  }
  5% {
    opacity: 1;
  }
  100% {
    -webkit-transform: scale(1);
    transform: scale(1);
    opacity: 0;
  }
}

@keyframes jumper {
  0% {
    opacity: 0;
    -webkit-transform: scale(0);
    transform: scale(0);
  }
  5% {
    opacity: 1;
  }
  100% {
    opacity: 0;
  }
}
<div id="preloader">
  <div class="jumper">
    <div></div>
    <div></div>
    <div></div>
  </div>
</div>

You can do it this way, using vanilla JavaScript, that you can adapt for jQuery as well.

You can remove that setTimout, added just for testing purpose.

window.addEventListener("load", () => {
  setTimeout(() => {
    document.getElementById("preloader").classList.add("hide");
  }, 1000);
});
#preloader {
  overflow: hidden;
  background-color: #fb5849;
  left: 0;
  right: 0;
  top: 0;
  bottom: 0;
  position: fixed;
  z-index: 99999;
  color: #fff;
  opacity: 1;
  transition: opacity 1s;
}

#preloader.hide {
  opacity: 0;
  pointer-events: none;
}

#preloader .jumper {
  left: 0;
  top: 0;
  right: 0;
  bottom: 0;
  display: block;
  position: absolute;
  margin: auto;
  width: 50px;
  height: 50px;
}

#preloader .jumper > div {
  background-color: #fff;
  width: 10px;
  height: 10px;
  border-radius: 100%;
  -webkit-animation-fill-mode: both;
  animation-fill-mode: both;
  position: absolute;
  opacity: 0;
  width: 50px;
  height: 50px;
  -webkit-animation: jumper 1s 0s linear infinite;
  animation: jumper 1s 0s linear infinite;
}

#preloader .jumper > div:nth-child(2) {
  -webkit-animation-delay: 0.33333s;
  animation-delay: 0.33333s;
}

#preloader .jumper > div:nth-child(3) {
  -webkit-animation-delay: 0.66666s;
  animation-delay: 0.66666s;
}

@-webkit-keyframes jumper {
  0% {
    opacity: 0;
    -webkit-transform: scale(0);
    transform: scale(0);
  }
  5% {
    opacity: 1;
  }
  100% {
    -webkit-transform: scale(1);
    transform: scale(1);
    opacity: 0;
  }
}

@keyframes jumper {
  0% {
    opacity: 0;
    -webkit-transform: scale(0);
    transform: scale(0);
  }
  5% {
    opacity: 1;
  }
  100% {
    opacity: 0;
  }
}
<div id="preloader">
  <div class="jumper">
    <div></div>
    <div></div>
    <div></div>
  </div>
</div>
