I’m having trouble understanding the logic of Regex, and I can’t find codes that make up the complete phone mask with IDD, DDD and phone with 8 and 9 digits with change of hyphen when typing directly in the field using for example the onkeyup event.

Follow mask +99 (99) 9999-9999 or +99 (99) 99999-9999

You can use the following expression:

/^(?:\+)[0-9]{2}\s?(?:\()[0-9]{2}(?:\))\s?[0-9]{4,5}(?:-)[0-9]{4}$/

Hard to understand? It was generated through the tool Simple Regex Language:

begin with literally "+",
digit exactly 2 times,
whitespace optional,
literally "(", digit exactly 2 times, literally ")",
whitespace optional,
digit between 4 and 5 times,
literally "-",
digit exactly 4 times,
must end

I believe that in this way it becomes self-explanatory.

See working here.

    +1 by Simple Regex Language. Sensational

  • @Arthurmenezes, yes, she has saved me many times.

  • I just hope they’re not saying that \s be it whitespace of " "

    @Guilhermelautert, any spacing, as is standard of regex. See documentation ("This Matches any whitespace Character. This includes a space, tab or new line.")

The below regex valid the mask you need

JS

var RegExp = /\+\d{2}\s\(\d{2}\)\s\d{4,5}-?\d{4}/g;
var t = "+99 (99) 99999-9999";
RegExp.test(t); //true

var t2 = "+99 (99) 9999-9999";
RegExp.test(t2); //true

var t3 = "+99 (99) 999999-9999";
RegExp.test(t3); //false

You can do it this way:

var regExp = /^\+?\d{2}?\s*\(\d{2}\)?\s*\d{4,5}\-?\d{4}$/g;
var telefone = '+55 (55) 23321-5454';
var resultado = regExp.test(telefone); //retorna true ou false
