HTML转义：让网页更安全稳定
HTML（HyperText Markup Language）是构建网页的基本语言，它通过标签和属性描述文本、图像、超链接等元素的呈现方式。然而，在HTML中使用某些特殊字符时，往往会导致显示或解析错误的问题。为了解决这些问题，HTML转义应运而生。
什么是HTML转义？
HTML转义指的是将HTML中的特殊字符转换为安全的字符实体，以防止浏览器将这些字符解析为标签或其他意义。比如，“
HTML 转义符
HTML转义符一般以&开头，以;结尾，包含一到多个字母或数字。这里是常见的HTML转义符及其代表的字符：
| 转义符 | 代表的字符 |
|---|---|
| & | & （和号） |
| > | > （大于号） |
| " | " （双引号） |
| ' | ' （单引号） |
HTML 转义实例
比如在HTML中要显示"Mickey & Minnie"，需要把&符号转义为&，所以正确的写法是：
Mickey & Minnie
同样地，要显示""，应该使用将其转义：
<html>
转义的应用场景
HTML中大量使用了一些特殊字符，像小于号（）、单引号（'）、双引号（"）和&符号等。如果这些特殊字符没有进行转义，浏览器会将它们解析为HTML标签或其他语言的处理指令，这就会破坏原本的网页结构，导致显示错误或还会诱发一些安全问题。为了确保网页能正确地呈现，而不会对安全稳定带来影响，发布内容时一定要及时做好HTML转义的处理。
结语
HTML转义是保障网站安全稳定的重要手段之一，可以有效地防止XSS攻击、SQL注入等安全问题的产生。在编写网页时，进行转义处理是必须的，不仅可以提高网页的可读性，而且可以保证网页的可靠性。尤其是在用户输入内容后，需要先对特殊字符进行转义，才能存储到数据库中，同时也要在输出到浏览器前进行转义，以免出现安全问题。

Managing State with useState(): A Practical TutorialApr 24, 2025 pm 05:05 PMuseState is superior to class components and other state management solutions because it simplifies state management, makes the code clearer, more readable, and is consistent with React's declarative nature. 1) useState allows the state variable to be declared directly in the function component, 2) it remembers the state during re-rendering through the hook mechanism, 3) use useState to utilize React optimizations such as memorization to improve performance, 4) But it should be noted that it can only be called on the top level of the component or in custom hooks, avoiding use in loops, conditions or nested functions.
