Key Points This article discusses the issue of using JavaScript/jQuery to dynamically insert scripts into DOM head tags during page loading. The author provides solutions for the following issues: IE8 error messages caused by encrypting pages/websites; loading a second script that references variables created by the first script resulted in an undefined error message; document.write causes page refresh. The author provides a final script that can be run in all browsers, including IE8.

Better Living Through Bookmarklets

Core points Bookmark applets are small JavaScript code embedded in browser bookmarks that enhance the functionality of a web browser and simplify the workflow of web developers. Bookmark applets have a wide range of uses, ranging from simple navigation tasks to more complex operations, such as modifying page content, analyzing page structure, and even automating tasks on the website. While bookmark applets are generally safe and reliable, they can cause namespace conflicts. This problem can be avoided by creating anonymous functions with its own variable scope as bookmark applets.

CSS font-size: A Definitive Font-Sizing Guide

The CSS font size setting seems simple, but the actual operation is challenging. Many developers rely on repeated adjustments to the font-size attribute to achieve visual effects, but find that the rendering results of different browsers are inconsistent. A deep understanding of CSS font size settings will result in twice the result with half the effort. Key Points The CSS font-size property can accept a variety of parameters, including absolute, relative, and length values. Unless explicitly overridden, elements inherit the font size of the parent element, which is crucial in specifying the relative size. Although absolute font size keywords can be used, their exact size can vary greatly across browsers, so developers usually avoid this rough approach. Relative Font Size Keywords adjust the font size according to the parent element size. Can

JavaScript Threading With HTML5 Web Workers

Key Points Web Workers in JavaScript is a powerful feature in the browser that allows developers to run ongoing processes in separate threads, thereby significantly improving client performance. However, they run independently of the browser UI thread and have some limitations, such as the inability to access DOM, global variables, or JavaScript functions in the page. To create and communicate with a dedicated Web Worker, the developer passes the JavaScript file name to a new instance of the Worker object and handles all communications through the event interface. The web script passes a single data parameter through the postMessage() method and passes the o

Sophisticated Sorting in JavaScript

The sorting mechanism of JavaScript is simple and easy to use, but it contains powerful and flexible functions. The sort() method can not only sort the array alphabetically or numerically, but also sort arbitrarily according to custom conditional logic. Core points: JavaScript's sort() function is a flexible tool that organizes arrays in a variety of ways, including custom arrangements defined based on conditional logic. The sort() function works by comparing two values (a and b) in each operation. If the function returns less than zero, a is before b; if it returns greater than zero, b is before a; if it returns zero, a and b are unchanged relative positions. JavaScr
