About

AjaxLoader library allows to create spinning activity indicators dynamically. It can be used instead of GIF image ajaxloaders. The main features of this library are the following:

How to use

AjaxLoader.js can be added to your site in three simple steps:

  1. Include ajaxloader.js (or the minified version ajaxloader.min.js for production) in your page. For example: 
    <script src="../ajaxloader.js"></script>
  2. Add to your page canvas object and set id. 
    <canvas id="spinner"></canvas>
  3. Create AjaxLoader object and call function show(): 
    var ajaxLoader = new AjaxLoader("spinner");
    ajaxLoader.show();
    You can specify options of the spinner before it's creation. For example: 
    var opts = {
    size: 32,           // Width and height of the spinner
    factor: 0.25,       // Factor of thickness, density, etc.
    color: "#000",      // Color #rgb or #rrggbb
    speed: 1.0,         // Number of turns per second
    clockwise: true     // Direction of rotation
};
var ajaxLoader = new AjaxLoader("spinner", opts);
ajaxLoader.show();
