jQuery Image ProgressBars Plugin

  • Last Updated : 09 Aug, 2020

In this article, we will learn how to implement image ProgressBar feature using jQuery Image ProgressBar plugin.

Note: Please download the jQuery Image ProgressBar plugin in the working folder and include the required files in the head section of your HTML code.

<link href=”progressbar.css” rel=”stylesheet” type=”text/css”/>
<script src=”jquery-3.3.1.min.js”></script>
<script src=”jquery.progressbar.js”></script>

Example : The following example demonstrates the basic functionality of Image ProgressBar plugin using jQuery createProgress() and getRandomNumber() functions. These functions make use of the plugin’s SetPercentage() method for setting the percentage complete. For getting random numbers, the JavaScript’s Math.ceil() and Math.floor() are used.
Background image along with the image selected for the progress bar is set. The plugin’s option backgroundOpacity is also set in the jQuery part of the code.
