HTML Progress Bar Using JavaScript Source Code


In this tutorial we will create a HTML Progress Bar using JavaScript. This code will dynamically display an animated progress bar when the user click the button. The code use onclick() function to call a specific method that will animate the progress bar by incrementing the width properties of an element and will stop if it reach the maximum width with setInterval(). This is a user-friendly program feel free to modify it.

We will use JavaScript to add some new feature to the website interface by actually written into an HTML page. It is what gives your page a different interactive elements and animation that engage a user.
