How to match value with Regex in angular

Question

I need to match regex and need to put condition based on result.. What I have tried is

var value1="4111111111111111"
    const str="^4[0-9]{12}(?:[0-9]{3})?$}"
var result=value1.match(str)
console.log(result)

Here I am getting value as null..

Can you please add the content inside value1 and the excepted result? — Jacopo Sciampi

your pattern is somthing like that? 4111111111111(111) or 4111111111111111 — miladfm

Try this :

var value1="4111111111111111"
var pattern = new RegExp('^4[0-9]{12}(?:[0-9]{3})?$}');
var result=pattern.test(value1);
console.log(result);

This will return either True or False

If you pattern is somthimg like that: 4111111111111111 or 4111111111111111

then use this code:

const str="^4[0-9]{12}([0-9]{3})?$";

'4111111111111'.match(str)
'4111111111111111'.match(str)
