Preventing Parent Click Events When Child Anchors Are Clicked
When incorporating clickable elements within parent elements and their children, it's common to encounter a scenario where both the parent and child click events are triggered simultaneously. This behavior occurs due to the bubbling nature of events in the DOM.
To prevent the parent's click event from firing in such cases, several solutions can be employed.
Checking the Event Origin
Utilizing the e.target property in the parent's click event handler allows for the identification of the actual element triggering the event. By comparing e.target to the parent element, it's possible to determine if the click originated from the parent or elsewhere within it.
Stopping Event Propagation
Alternatively, attaching a click event handler to the child anchors and calling e.stopPropagation() within it prevents the event from bubbling up to the parent. In this way, the parent's click event will not be triggered when its child anchors are clicked.
Code Example:
$("#clickable").click(function(e) {
if ($(e.target).is("div")) { // Check if the event originated from the <div>
window.location = url;
return true;
}
});
$("#clickable a").click(function(e) {
// Do something specific to the anchor
e.stopPropagation();
});
By applying any of these methods, it becomes possible to selectively handle click events based on the target element, ensuring that the parent's click event is fired only when it's the intended target.

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
