HTML URL Encoding
What is URL Encoding?
URL encoding, also known as percent encoding, is a mechanism for encoding information in a Uniform Resource Identifier (URI). It replaces unsafe ASCII characters with a "%" followed by two hexadecimal digits.
Why Use URL Encoding?
URLs can only be sent over the Internet using the ASCII character-set. Since URLs often contain characters outside the ASCII set, the URL has to be converted into a valid ASCII format.
Common Encoded Characters
For example, spaces are encoded as "%20", and special characters like "&" are encoded as "%26".
How to Encode URLs?
In HTML, you can use JavaScript's encodeURIComponent() function to encode a URL.
Example of URL Encoding
Consider the URL: https://example.com/search?query=hello world. The encoded version would be: https://example.com/search?query=hello%20world.
let url = "https://example.com/search?query=hello world";
let encodedUrl = encodeURIComponent(url);
console.log(encodedUrl);
Decoding URLs
To decode an encoded URL, you can use JavaScript's decodeURIComponent() function.
Console Output:
https%3A%2F%2Fexample.com%2Fsearch%3Fquery%3Dhello%20world
