What encoding format to choose for jQuery
jQuery is a very popular JavaScript library with many powerful features and functions that make web development easier and simpler. Coding format is also a very critical part when using jQuery, because it will directly affect the readability, maintainability and reusability of the code. This article will introduce some common encoding formats and the reasons why jQuery chooses which encoding format.
1. UTF-8 encoding format
UTF-8 is a universal character encoding format that can represent almost all characters. It is a variable-length encoding method that uses 1 to 4 bytes to represent each character. In web development, UTF-8 is widely used in the encoding of text files such as HTTP requests and responses, HTML pages, CSS and JavaScript. The basic format for using UTF-8 encoding format in jQuery is as follows:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>jQuery UTF-8 编码格式示例</title>
<script src="https://cdn.bootcdn.net/ajax/libs/jquery/3.6.0/jquery.min.js"></script>
</head>
<body>
<script>
$(document).ready(function(){
// 在此处编写代码
});
</script>
</body>
</html>In the above code, set the charset attribute of the tag to "UTF-8" to use UTF in jQuery -8 encoding format.
2. GBK encoding format
GBK is China’s national standard. It is a double-byte encoding format that can represent Chinese, Japanese, Korean and other characters. In Web development, the GBK encoding format is also widely used in encoding various text files. Unlike UTF-8, the GBK encoding format is a fixed-length encoding method, and each character is represented by two bytes. The basic format for using the GBK encoding format in jQuery is as follows:
<!DOCTYPE html>
<html>
<head>
<meta charset="GBK">
<title>jQuery GBK 编码格式示例</title>
<script src="https://cdn.bootcdn.net/ajax/libs/jquery/3.6.0/jquery.min.js"></script>
</head>
<body>
<script>
$(document).ready(function(){
// 在此处编写代码
});
</script>
</body>
</html>In the above code, set the charset attribute of the tag to "GBK" to use the GBK encoding format in jQuery.
3. Which encoding format to choose
When choosing which encoding format, you need to consider the following factors:
1. International support: If your website If you need to support multiple languages or character sets, the UTF-8 encoding format is a good choice. Because it can represent almost all characters without causing conflicts between character sets.
2. Page size: UTF-8 encoding format requires more bytes to represent a character, so the page size will be larger. If your website needs to reduce the page size as much as possible, then the GBK encoding format will be more suitable for you.
3. Target audience: If the target audience of your website is Chinese users mainly from China or outside China, then the GBK encoding format will be more suitable for you. Because these users should be more familiar with this encoding format, and may not be familiar with UTF-8 encoding format.
In short, when choosing which encoding format, you need to make a choice based on specific needs and situations. No matter which coding format you choose, you need to ensure that the code is clear, concise, and easy to maintain.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
