jquery Chinese address garbled code

jQuery is a very popular JavaScript library that can help developers operate Web pages more conveniently. However, when we use jQuery, we often encounter the problem of garbled Chinese addresses, which brings great difficulties to our development. This article will discuss this problem and propose solutions.

First of all, let’s take a look at why the Chinese address garbled problem occurs. In fact, the essence of this problem is the difference in how browsers encode URLs. In the W3C specification, URLs can only contain English letters, numbers and special symbols (., -, _, ~,:, /, ?, #, [,], @,!, $, &, ', (,) ,*, ,,,; and =), other characters need to be encoded. Different browsers use different character sets when encoding, resulting in different URL encoding results.

Another factor that causes garbled Chinese addresses is the configuration of the server. When the server uses different encoding methods, the encoding results of the same URL in different browsers will be different.

So, how to solve the problem of garbled Chinese addresses? There are several methods:

1. Use the encodeURIComponent() function for encoding. The encodeURIComponent() function is a function in JavaScript that can URL-encode a string. If we need to use a Chinese address when using jQuery, we can use the encodeURIComponent() function to encode the address, and then pass the encoded result to jQuery. For example:

var url = "http://www.example.com/中文地址/";
$.ajax({
    url: encodeURIComponent(url),
    ...
});

Doing this can ensure that the encoding results of the URL in different browsers are consistent.

2. Use the encodeURIComponent() function to encode and splice the URL yourself

Sometimes, we need to splice the URL ourselves instead of passing the URL as a parameter to jQuery. In this case, we can first use the encodeURIComponent() function to encode the address, and then manually splice the URL. For example:

var host = "http://www.example.com/";
var path = encodeURIComponent("中文地址/");
var url = host + path;
$.ajax({
    url: url,
    ...
});

Doing this can also ensure that the encoding results of the URL in different browsers are consistent.

3. Set the encoding method uniformly on the server side

If we can control the server, we can set the encoding method uniformly on the server side. This avoids differences in the encoding methods of different browsers. In Apache and Nginx servers, you can use the following configuration to set the encoding method:

Apache:

AddDefaultCharset utf-8

Nginx:

charset utf-8;

After the setting is completed, you can use the Chinese address , without any encoding.

4. Use UTF-8 encoding

UTF-8 is a universal character encoding method that supports all characters including Chinese. If we set the encoding method of the website to UTF-8, we can use the Chinese address directly without any encoding when using jQuery. In HTML, you can use the following tag to set the page encoding method:

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

Of course, this method needs to ensure that all pages and data are encoded in UTF-8, otherwise garbled characters will appear.

Summary:

When using jQuery, we often encounter the problem of garbled Chinese addresses. The essence of this problem is the difference in how browsers encode URLs, and the way servers encode them. In order to solve this problem, we can use the encodeURIComponent() function to encode, or set the encoding method uniformly on the server side, or use UTF-8 encoding. These methods can ensure that we will not encounter garbled characters when using Chinese addresses.
