encode url component code example

Example 1: encodeuricomponent js

var set1 = ";,/?:@&=+$";  // Reserved Characters
var set2 = "-_.!~*'()";   // Unescaped Characters
var set3 = "#";           // Number Sign
var set4 = "ABC abc 123"; // Alphanumeric Characters + Space

console.log(encodeURI(set1)); // ;,/?:@&=+$
console.log(encodeURI(set2)); // -_.!~*'()
console.log(encodeURI(set3)); // #
console.log(encodeURI(set4)); // ABC%20abc%20123 (the space gets encoded as %20)

console.log(encodeURIComponent(set1)); // %3B%2C%2F%3F%3A%40%26%3D%2B%24
console.log(encodeURIComponent(set2)); // -_.!~*'()
console.log(encodeURIComponent(set3)); // %23
console.log(encodeURIComponent(set4)); // ABC%20abc%20123 (the space gets encoded as %20)

Example 2: encodeuricomponent

The encodeURIComponent() function encodes a URI by replacing each instance of certain characters by one, two, three, or four escape sequences representing the UTF-8 encoding of the character.
console.log(encodeURIComponent('?x=test'));
// expected output: "%3Fx%3Dtest"
