Navigating Web Pages to Specific Anchors using JavaScript
Navigating a web page to a specific anchor can be achieved with JavaScript by utilizing the location.hash property. Anchors are specified in HTML using the name or id attributes.
Code:
The following JavaScript code provides a simple solution to scroll the page to a given anchor:
function scrollTo(hash) {
location.hash = "#" + hash;
}
Usage:
This function takes a single parameter, hash, which corresponds to the name or id of the anchor. Calling scrollTo('anchorName') will scroll the page to the element with the specified anchorName.
Example:
In the following HTML structure:
<html>
<body>
<a name="section1">...</a>
<a name="section2">...</a>
</body>
</html>
Calling scrollTo('section2') would smoothly scroll the page to the section with the section2 anchor. This mimics the effect of directly accessing the URL http://server.com/path#section2, ensuring the anchor is visible near the top of the page.
Note:
This method does not require jQuery or any additional libraries and works effectively on various browsers.

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
