1 JavaScript Progress Bar
A JavaScript progress bar is a UI component that visually indicates the completion of an operation, with JavaScript being essential for dynamically calculating and updating the progress. While the bar itself is styled with CSS, JavaScript provides the logic to control its state. For task-oriented progress like a file upload or a form submission, JavaScript updates the width of an inner bar element to reflect the percentage complete. A popular implementation is a scroll progress bar, where JavaScript listens for the scroll event, calculates the scroll percentage of the page, and updates the bar's width in real-time. Another use is for timer-based operations, where the bar fills up over a set duration. This collection showcases a variety of progress bars built with vanilla JavaScript, providing examples of animated indicators for tasks, page scroll progress, and timers to help you add clear visual feedback to your web applications.
Battle.net Style Animated Progress Bar
A visually rich, animated progress bar inspired by the Battle.net UI. This progress bar features smooth gradient fills, subtle pulsing animations, and dynamic color changes depending on the progress percentage: red for low, orange for moderate, yellow for high, green for near-complete, and blue when finished. The bar updates in real-time with a randomized speed for a natural loading effect, and displays a percentage label that changes to "Complete" once fully loaded.
