JavaScript and URL Encoding - A Comprehensive Guide

URL encoding in javascript is probably the easiest of the lot and hence we are covering it the first. You can encode URI components like a string or part of a string or a URL using the encodeURIComponent()

Here is a quick example, of how to encode a URL or string using javascript

const value = 'Tööls Cönverters xyz URLEncoder@Javascript'
const encodedValue = encodeURIComponent(value)
console.log(encodedValue)

Output:

// T%C3%B6%C3%B6ls%20C%C3%B6nverters%20xyz%20URLEncoder%40Javascript

If you wish to encode the query string of a URL and the entire URL, you can simply pass the query string to the function and then append the result to form your complete URL. Let's look at an example:

const baseUrl = 'https://www.google.com/search?q='
const value = 'Tööls Cönverters xyz URLEncoder@Javascript'
const encodedValue = encodeURIComponent(value)
console.log(encodedValue)

Output:

// https://www.google.com/search?q=T%C3%B6%C3%B6ls%20C%C3%B6nverters%20xyz%20URLEncoder%40Javascript

You can try to see the output of this by clicking the url or pasting it in a new tab Tööls Cönverters xyz URLEncoder@Java
