How to solve jquery html Chinese garbled problem

With the rapid development of mobile Internet, web design has gradually become an increasingly important industry. As one of the basic skills of web design, "front-end development" has also gradually attracted attention. In front-end development, jQuery is one of the most commonly used JavaScript libraries. I believe that many front-end engineers have encountered the jQuery HTML Chinese garbled problem. I will introduce this problem and solution in detail below.

1. Problem description

When using jQuery, we often add HTML code to web pages in the following ways:

$('body').append('
你好，世界！
');

In the above code, we select through jQuery The tool selects the body element in the web page, appends a div tag through the .append() method, and adds a Chinese character "Hello, world!" in it. However, when we viewed the source code on the page, the Chinese characters were garbled;

When we viewed the source code on the page, we found that the Chinese characters had been escaped into Unicode encoding:

\u4F60\u597D\uFF0C\u4E16\u754C\uFF01

The reason for this phenomenon is: in jQuery, when adding HTML code through the above method, Chinese characters will be automatically escaped into Unicode encoding form through JavaScript's built-in function, and then added to the web page.

2. Solution

In order to solve the jQuery HTML Chinese garbled problem, we can use the following two methods:

Method 1: Use HTML entity characters

HTML entity characters are special characters based on ASCII code, which can avoid the problem of garbled Chinese characters. The writing format of HTML entity characters is "&entity name;", where "entity name" represents a specific character. For example, " " represents the space character.

Therefore, we can replace Chinese characters with HTML entity characters to avoid the problem of Chinese garbled characters. For example, change the above code to:

$('body').append('
你好，世界！
');

In this way, Chinese characters can be displayed normally on the web page.

It should be noted that there are many writing formats for HTML entity characters. For example, "你" and "you" both represent the Chinese character "you". In addition, different browsers have different support for HTML entity characters, so you need to use them with caution.

Method 2: Use JavaScript transcoding function

In addition to using HTML entity characters, we can also use the transcoding function provided by JavaScript to convert Chinese characters into Unicode encoded characters to solve the problem Chinese garbled characters problem. Commonly used transcoding functions include: escape(), encodeURI(), encodeURIComponent(), etc.

For example, we can change the above code to:

$('body').append('
' + encodeURIComponent('你好，世界！') + '
');

In this way, Chinese characters can be displayed normally on the web page.

It should be noted that although this method can avoid the problem of Chinese garbled characters, you need to pay attention to the encoding method of characters when writing code to avoid shortcomings such as unreadable code.

3. Summary

In front-end development, encountering the jQuery HTML Chinese garbled problem is one of the common problems. In order to solve this problem, we can use HTML entity characters or JavaScript transcoding functions to replace Chinese characters to avoid garbled characters. Which method to use needs to be chosen based on the specific application scenario. No matter which method you choose, you need to pay attention to the encoding method of characters when writing code to avoid shortcomings such as unreadable code.
