To encode a URL, you use the encodeURIComponent function in JavaScript. This function converts characters that are not allowed in a URL into their encoded form. Here’s how you do it:
const url = ‘https://example.com/search?query=hello world&sort=ascending’;
const encodedUrl = encodeURIComponent(url);
console.log(encodedUrl);
In this example, encodeURIComponent will encode special characters like spaces and question marks. Note that encodeURIComponent is intended for encoding query parameters or parts of a URL, not the entire URL. For encoding the entire URL, you should use encodeURI:
const url = ‘https://example.com/search?query=hello world&sort=ascending’;
const encodedUrl = encodeURI(url);
console.log(encodedUrl);
Use encodeURIComponent for query parameters and encodeURI for the entire URL to ensure proper encoding.
Since URLs often contain characters outside the ASCII set, the URL has to be converted into a valid ASCII format. URL encoding replaces unsafe ASCII characters with a “%” followed by two hexadecimal digits. URLs cannot contain spaces. URL encoding normally replaces a space with a plus (+) sign or with %20.
