如何加入三个正则表达式

Question

I have a code:

this.valor = String(this.valor).replace(/R\$/, '');
this.valor = String(this.valor).replace(/,/g, '');
this.valor = String(this.valor).replace(/\./g, '');

Example: put R$1.000,00 and return 100000

How to convert in a one line?

Answer 1

You could try something like this, however, I don't feel like I should suggest you to go down this path.

Blindly stripping , and . out might lead to wrong data, it seems like you are parsing a currency here and $1.000,00 doeesn't necessarily equal to 100000

 const sanitize = (string) => string.replace(/[R$.,]/g, ''); console.log(sanitize('R$1.000,00'));

Answer 2

Simply use " | " between regular expressions to combine them. As for solution Hitmands answer is recommended

 console.log("R$1.000,00".replace(/\.|R\$|\,/g,''))
