Avoiding Multiple Triggering of jQuery Click Events
In web development, using jQuery click event handlers effectively can sometimes pose challenges. A common problem faced is the unwanted multiple triggering of these events, leading to unexpected behavior in applications.
One such instance was encountered in an attempt to create a video poker game in Javascript. The function used to handle bets involved click event handlers attached to bet buttons. However, these handlers were executing more than once, resulting in incorrect betting amounts.
By analyzing the provided code, the issue can be narrowed down to the lack of proper unbinding of existing click events. When a click event is assigned to a button, jQuery adds an event listener to that button. If the same click event is reassigned without first unbinding the previous listener, multiple listeners are created, causing multiple executions.
To prevent this unwanted behavior, the code should be modified to unbind any existing click events before reassigning a new one. This can be accomplished using the unbind() method.
Here's the corrected code:
$(".bet").unbind().click(function() {
// Stuff
});
By explicitly unbinding the existing click event handlers before assigning new ones, the code ensures that each click triggers the event only once, as intended.

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
