Detecting When Users Stop Scrolling with jQuery's scroll()
Problem Overview:
You're using jQuery's scroll() function to remove a class from elements while scrolling. However, you want to re-apply that class when scrolling stops.
Answer Explanation:
The provided solution utilizes a timer to detect when a user has stopped scrolling. It employs the scrollTimer variable to track the timeout. When the scroll() event occurs, the timer is cleared, and a new timer is set using setTimeout(). This timer calls a callback function after a specified delay (250ms in the example).
Enhanced Solution:
The provided code snippets include an extension for jQuery's on() event handler called $.unevent.js. This extension allows you to specify a delay after which the callback function should be triggered. This is ideal for scenarios where you only want to fire an event after a certain amount of time has passed.
Implementation:
Here's how to use the updated version:
$(window).on('scroll', function(e) {
console.log(e.type + '-event was 250ms not triggered');
}, 250);
You can adjust the delay (in milliseconds) as needed.
Additional Notes:
- Ensure you check the GitHub repository for the latest updates of $.unevent.js.
- This solution can be applied to other events, such as resize, by simply replacing scroll with the desired event in the on() method.

How to work with dates and times in js?
Jul 01, 2025 am 01:27 AM
The following points should be noted when processing dates and time in JavaScript: 1. There are many ways to create Date objects. It is recommended to use ISO format strings to ensure compatibility; 2. Get and set time information can be obtained and set methods, and note that the month starts from 0; 3. Manually formatting dates requires strings, and third-party libraries can also be used; 4. It is recommended to use libraries that support time zones, such as Luxon. Mastering these key points can effectively avoid common mistakes.

What is event bubbling and capturing in the DOM?
Jul 02, 2025 am 01:19 AM
Event capture and bubble are two stages of event propagation in DOM. Capture is from the top layer to the target element, and bubble is from the target element to the top layer. 1. Event capture is implemented by setting the useCapture parameter of addEventListener to true; 2. Event bubble is the default behavior, useCapture is set to false or omitted; 3. Event propagation can be used to prevent event propagation; 4. Event bubbling supports event delegation to improve dynamic content processing efficiency; 5. Capture can be used to intercept events in advance, such as logging or error processing. Understanding these two phases helps to accurately control the timing and how JavaScript responds to user operations.

How can you reduce the payload size of a JavaScript application?
Jun 26, 2025 am 12:54 AM
If JavaScript applications load slowly and have poor performance, the problem is that the payload is too large. Solutions include: 1. Use code splitting (CodeSplitting), split the large bundle into multiple small files through React.lazy() or build tools, and load it as needed to reduce the first download; 2. Remove unused code (TreeShaking), use the ES6 module mechanism to clear "dead code" to ensure that the introduced libraries support this feature; 3. Compress and merge resource files, enable Gzip/Brotli and Terser to compress JS, reasonably merge files and optimize static resources; 4. Replace heavy-duty dependencies and choose lightweight libraries such as day.js and fetch
