Creating DOM Elements from HTML Strings
While jQuery offers a convenient mechanism for creating DOM elements from HTML strings, this functionality can also be achieved using built-in DOM methods or through the Prototype library.
DOM Methods
For older browsers, as well as node/jsdom (which at the time of writing did not support HTML elements), the following method can be employed:
function createElementFromHTML(htmlString) {
var div = document.createElement('div');
div.innerHTML = htmlString.trim();
// Change this to div.childNodes to support multiple top-level nodes.
return div.firstChild;
}
It is important to note that this method will not work for some elements that cannot be legally children of a
Prototype Library
Alternatively, the Prototype library provides a built-in method for creating elements from HTML strings through its update() method. Here's an example:
var element = $(document.createElement('li')).update('<li>text</li>');
Use Cases
Both built-in DOM methods and the Prototype library offer reliable ways of creating DOM elements from HTML strings, particularly for older browsers or in scenarios where jQuery is not utilized. These methods provide a flexible and robust approach for dynamically generating DOM content based on HTML markup.

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
A definitive JS roundup on JavaScript modules: ES Modules vs CommonJS
Jul 02, 2025 am 01:28 AM
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.
How to make an HTTP request in Node.js?
Jul 13, 2025 am 02:18 AM
There are three common ways to initiate HTTP requests in Node.js: use built-in modules, axios, and node-fetch. 1. Use the built-in http/https module without dependencies, which is suitable for basic scenarios, but requires manual processing of data stitching and error monitoring, such as using https.get() to obtain data or send POST requests through .write(); 2.axios is a third-party library based on Promise. It has concise syntax and powerful functions, supports async/await, automatic JSON conversion, interceptor, etc. It is recommended to simplify asynchronous request operations; 3.node-fetch provides a style similar to browser fetch, based on Promise and simple syntax
What are best practices for writing clean and maintainable JavaScript code?
Jun 23, 2025 am 12:35 AM
To write clean and maintainable JavaScript code, the following four points should be followed: 1. Use clear and consistent naming specifications, variable names are used with nouns such as count, function names are started with verbs such as fetchData(), and class names are used with PascalCase such as UserProfile; 2. Avoid excessively long functions and side effects, each function only does one thing, such as splitting update user information into formatUser, saveUser and renderUser; 3. Use modularity and componentization reasonably, such as splitting the page into UserProfile, UserStats and other widgets in React; 4. Write comments and documents until the time, focusing on explaining the key logic and algorithm selection
How does garbage collection work in JavaScript?
Jul 04, 2025 am 12:42 AM
JavaScript's garbage collection mechanism automatically manages memory through a tag-clearing algorithm to reduce the risk of memory leakage. The engine traverses and marks the active object from the root object, and unmarked is treated as garbage and cleared. For example, when the object is no longer referenced (such as setting the variable to null), it will be released in the next round of recycling. Common causes of memory leaks include: ① Uncleared timers or event listeners; ② References to external variables in closures; ③ Global variables continue to hold a large amount of data. The V8 engine optimizes recycling efficiency through strategies such as generational recycling, incremental marking, parallel/concurrent recycling, and reduces the main thread blocking time. During development, unnecessary global references should be avoided and object associations should be promptly decorated to improve performance and stability.
