具有十进制识别的javascript货币格式

Question

i stumbled across your this site while looking for a solution for my problem. I m new to javascript but already starting to love it. This one problem i can´t solve on my own yet. Here s the deal:

I need the have a script for Acrobat that tells my field that:
1. It´sa currency field always ending with (blank)€
2. The user needs to be able to enter prices with 2 decimal place (for example 123,23 €)
3. If the user enters 123,00 it should automatically turn into 123 €.

Like I said I ma newbie in this area but eager to learn, so your help is very much appreciated.

Answer 1

JavaScript is unnecessary in this case. Because you are using Acrobat, you can simply set the format on the field to be what you want. See image below.

Answer 2

A JS solution to this is to use string.toLocaleString . (From https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Number/toLocaleString )

var number = 123456.789;

// request a currency format
console.log(number.toLocaleString('de-DE', { style: 'currency', currency: 'EUR'}));
// → 123.456,79 €

Instead of "de-DE" you'll probably want to use your own country code.
