How to decode url-encoded string in javascript

Question

I use javascript / jquery to fill dom elements that contain umlauts:

var text1 = \"Unser platonisches Internetreich droht in die H%E4nde einer bewaffneten Mi         


        

Answer 1

Use either of the following built in JavaScript function to decode any encoded text. No need for jquery or any other library.

const text1 = "Unser platonisches Internetreich droht in die H%E4nde einer bewaffneten Miliz zu fallen."

console.log(decodeURI(text1))

console.log(decodeURIComponent(text1))

Answer 2

That is not UTF-8, that is percent encoding also known as url encoding.

You can use decodeURIComponent() to convert it back before displaying it

$("#quote1 span").html(decodeURIComponent(text1));
