Correct the phone number format using regex in JS

I have users entering the numbers as

01122449000

The correct format is +5<last 11 digits>

I have tried with

"+5" + tel.match(/\d+/g)[0]

Butists giving incorrect results

function getFormattedPhone(a) {
    if (a) return (a = a.match(/\d+/g)) ? "'+2" + a.join("").substr(-11) : ""
};

This worked for me.

You could try stripping whitespace then retaining just the first digit and final 11 digits:

var phone = "5 011 223 39000 01122449000";
var output = phone.replace(/\s+/g, "").replace(/^(\d)\d*(\d{11})$/, "+$1$2");
console.log(phone + "\n" + output);

if (/^\+5\d{11}$/.test(output)) {
    console.log("valid phone number");
}
else {
    console.log("invalid phone number");
}
