How Can I Match Non-ASCII Characters in JavaScript/jQuery Using Regular Expressions?
Dec 09, 2024 am 11:12 AMMatching Non-ASCII Characters with Regular Expressions in JavaScript/jQuery
Non-ASCII characters often present a challenge when working with text in JavaScript/jQuery. To match words individually in an input string, regardless of language, it's essential to handle characters like ü, ?, ?, and ? that lie outside the ASCII character set.
One of the most straightforward solutions is to use the following regular expression:
[^\x00-\x7F]+
This pattern matches any character that is not within the ASCII character set (0-127, i.e., 0x0 to 0x7F). It effectively selects characters with Unicode values greater than 127.
Alternatively, for Unicode matching, you can use:
[^\u0000-\u007F]+
This pattern excludes all characters in the Unicode range 0x0000 to 0x007F, allowing for a broader match.
To understand Unicode ranges better, you can explore the following resources:
- Code charts list of Unicode ranges
- Unicode block filter regex tool
By incorporating these regular expressions into your JavaScript/jQuery code, you can efficiently identify and process non-ASCII characters in your input strings, regardless of language or character encoding.

Java and JavaScript are different programming languages, each suitable for different application scenarios. Java is used for large enterprise and mobile application development, while JavaScript is mainly used for web page development.

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.

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.

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

The main difference between ES module and CommonJS is the loading method and usage scenario. 1.CommonJS is synchronously loaded, suitable for Node.js server-side environment; 2.ES module is asynchronously loaded, suitable for network environments such as browsers; 3. Syntax, ES module uses import/export and must be located in the top-level scope, while CommonJS uses require/module.exports, which can be called dynamically at runtime; 4.CommonJS is widely used in old versions of Node.js and libraries that rely on it such as Express, while ES modules are suitable for modern front-end frameworks and Node.jsv14; 5. Although it can be mixed, it can easily cause problems.
