2020 Update

Use encodeURIComponent, an example pulled from MDN.

// encodes characters such as ?,=,/,&,:
console.log(encodeURIComponent('?x=шеллы'));
// expected output: "%3Fx%3D%D1%88%D0%B5%D0%BB%D0%BB%D1%8B"

console.log(encodeURIComponent('?x=test'));
// expected output: "%3Fx%3Dtest"

encodeURI which expects a complete URI could be worth a look as well.

My previous suggestion was to use escape() method, but now that it has been deprecated and soon will be dropped as well.

Programmers should not use or assume the existence of these features and behaviours when writing new ECMAScript code
