Javascript regex Currency symbol in a string

Question

so I have a formatting string that can be $#,###.00 or "£#,###.00 and I would like to get the currency symbol form it here is the code that I'm using:

 currencySymbol =  format.match(/\p{Sc}/);

I would like currencySymbol to be equal to "$" or "£" but it's not working currencySymbol is null.

not sure if it's always the first symbol for euros for example it's the last symbol — Hassene Benammou

@HasseneBenammou does my answer below help you out? What exactly are you trying to accomplish? If you are interested in finding the various currency symbols, take a look at CLDR. For example, unicode.org/repos/cldr-aux/json/26/main/en/currencies.json . If you want to add markups on the currency symbols, I can also help you out. — Rafael Xavier

Short answer:

/[\$\xA2-\xA5\u058F\u060B\u09F2\u09F3\u09FB\u0AF1\u0BF9\u0E3F\u17DB\u20A0-\u20BD\uA838\uFDFC\uFE69\uFF04\uFFE0\uFFE1\uFFE5\uFFE6]/

Long answer:

A JavaScript regular expression equivalent to /\p{Sc}/ is:

ScRe = /[\$\xA2-\xA5\u058F\u060B\u09F2\u09F3\u09FB\u0AF1\u0BF9\u0E3F\u17DB\u20A0-\u20BD\uA838\uFDFC\uFE69\uFF04\uFFE0\uFFE1\uFFE5\uFFE6]/

ScRe.test("$"); // true
ScRe.test("£"); // true
ScRe.test("€"); // true

The above has been generated by:

$ npm install regenerate
$ npm install unicode-7.0.0
$ node 
> regenerate().add(require('unicode-7.0.0/categories/Sc/symbols')).toString();

\p{Sc} is PCRE regex property and Javascript doesn't support it.

In Javascript you need to use specific symbols in character class to match them like this:

/[$£]/

should I list all the currencies possible? because it can be anything.

Unfortunately yes, you will need to list all possible currencies in this character class in JS.

You could use an addon like XregExp.

You can also use this /(kr|$|£|€)/.

currencySymbol = format.match(/(kr|$|£|€)/);
