How to use it:
1. Make sure you have jQuery library and the jQuery Gradient Progress Bar loaded in your document.
<script src="//code.jquery.com/jquery-2.1.4.min.js"></script> <script src="gradient-progress-bar.min.js"></script>
2. Create a DIV element that will be served as the container for your progress bar.
<div class="progress-bar"></div>
3. Call the plugin to render an animated progress bar with a preset gradient fill into the DIV element you just created.
$('.progress-bar').gradientProgressBar({ value: 0.75, // percentage size: 300, // width fill: { // gradient fill gradient: ["green", "yellow", "red"] } });
4. All default options which can be used to customize the progress bars.
/** * This is the only required option. It should be from 0.0 to 1.0 * @type {number} */ value: 0.0, /** * Size of the progress bar in pixels * @type {number} */ size: 100.0, /** * Width of the bar. By default it's auto-calculated as 1/14 of size, but you may set it explicitly in pixels * @type {number|string} */ thickness: 'auto', /** * Fill of the bar. You may set it to: * - solid color: * - { color: '#3aeabb' } * - { color: 'rgba(255, 255, 255, .3)' } * - linear gradient (left to right): * - { gradient: ['#3aeabb', '#fdd250'], gradientAngle: Math.PI / 4 } * - { gradient: ['red', 'green', 'blue'], gradientDirection: [x0, y0, x1, y1] } */ fill: { gradient: ['#3aeabb', '#fdd250'] }, /** * Color of the "empty" bar. Only a color fill supported by now * @type {string} */ emptyFill: 'rgba(0, 0, 0, .1)', /** * Animation config (see jQuery animations: http://api.jquery.com/animate/) */ animation: { duration: 1200, easing: 'gradientProgressBarEasing' }, /** * Default animation starts at 0.0 and ends at specified `value`. Let's call this direct animation. * Also you may specify any other value from 0.0 to 1.0 * @type {number} */ animationStartValue: 0.0, /** * Bar line cap ('butt', 'round' or 'square') * Read more: https://developer.mozilla.org/en-US/docs/Web/API/CanvasRenderingContext2D.lineCap * @type {string} */ lineCap: 'butt',
