Wave Loader is a simple jQuery plugin that creates a circular loader with a smooth wave loading effect using Html5 canvas and requestAnimationFrame.

How to use it:

1. Include the jQuery JS library and the jQuery wave loader plugin on the web page.

<script src="//ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="js/loader.js"></script>

2. Create a container for the wave loader.

<div class="loader"></div>

3. Add the required CSS to your CSS file, or to the page

.loader {
  width: 100px;
  height: 100px;
  background: #ffffff;
  border: 10px solid #0d283b;
  border-radius: 50%;
  position: relative;
  overflow: hidden;
}

.counter {
  width: 100%;
  line-height: 100px;
  font-size: 24px;
  font-weight: bold;
  color: #000000;
  text-align: center;
  position: absolute;
  top: 0;
  left: 0;
  opacity: 0.5;
}

4. Initialize the plugin to create a sample wave loader.

$(function () {
  $('.loader').loader();

  var progr = 1;
  setInterval(function () {
    $('.loader').loader('setProgress', ++progr);
  }, 100);
});

5. Available options to customize the wave loader.
