I need to format phone number for example by replace()
:
From: +48 XX XXX XX XX
where X
is a number.
Example: +48 12 345 67 89
To: +48 XXX XXX XXX
Example: +48 123 456 789
Edit:
My work:
- First, I tried to remove the spaces in string:
phone.replace(' ', '');
:
Before: +48 12 312 31 23
After: +4812 312 31 23
Conclusion: Something is wrong because it only formatted the first space instead of everything.
- I also tried to separate it into parts, based on other questions about regex:
phone.replace(/(d{3})(d{3})(d{3})(d{3})/gi, '$1 $2 $3 $4');
and
phone.replace(/(d{3})" "(d{3})" "(d{3})" "(d{3})/gi, '$1 $2 $3 $4');
and many other configurations like this.
Before: +48 12 312 31 23
After: +48 12 312 31 23
Conclusion: For sure, something is wrong, there is no change. The problem is with the regex.

You could use a regex replacement approach here:
var input = "+48 12 345 67 89"; var output = input.replace(/s+/g, "") .replace(/^(+d{2})(d{3})(d{3})(d{3})$/, "$1 $2 $3 $4"); console.log(input + " => " + output);
