Splitting the <script> Tag Within document.write() Calls: Why?</h2> <p><strong>Introduction:</strong></p> <p>The practice of splitting HTML tags into multiple parts within document.write() has baffled many developers. In particular, the splitting of the <script> tag has raised questions regarding its purpose. This article delves into the reasons behind this technique, shedding light on the challenges and considerations involved.</p> <p><strong>Challenges with </script> Tag Placement:
The primary reason for splitting tags is due to an interesting behavior in SGML, the markup language that underlies HTML. According to SGML, script blocks are terminated by any "end-tag open" (ETAGO) sequence, including
If the tag were not split, it would prematurely end the enclosing <script></script> block. To prevent this, developers must split the tag and place the
Browser Compatibility and XHTML Considerations:
Splitting the tag also addresses browser compatibility issues. While browsers generally parse HTML as CDATA, treating any tag.
In XHTML, where script blocks are not treated specially, all unescaped < characters must be escaped using &. However, this can lead to confusion when browsers parse XHTML as HTML. Splitting the tag ensures compatibility with both types of parsers.
Alternative Approaches:
While splitting tags within document.write() is a common practice, it is not the only option. A more elegant solution is to encode the entire

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
