Is there a functionality in JavaScript to convert values into specific locale formats?

Question

Is there a built in function of JavaScript to convert a string into a particular locale (Euro in my case)?

E.g. 50.00 should get converted to 50,00 €.

Answer 1

I found a way to do this at this page.

You can you toLocaleString without using toFixed before it. toFixed returns a string, toLocaleString should get a number. But you can pass an options object with toLocaleString, the option minimumFractionDigits could help you with the functionality toFixed has.

50.toLocaleString('de-DE', {     style: 'currency',      currency: 'EUR',      minimumFractionDigits: 2  }); 

Checkout all the other options you can pass with this function.

Answer 2

50.00 is a unit-less value. The best you can do is convert 50.00 to 50,00 and then append the € yourself. Therefore, just use Number.toLocaleString().

var i = 50.00; alert(i.toLocaleString() + ' €'); // alerts '50.00 €' or '50,00 €'
