Separating string with JavaScript

Question

The goal

99999999 to 9999 9999.

The problem

I searched for String.split, but I couldn't apply. I don't want to separate the string into two variables, I just want to separate the string to displaying proposals.

The scenario

There is the following fragment on my application:

var contactPhone = "91929394";

And I want to separate 91929394 into 9192 9394 by calling the same variable (contactPhone).

Clarifying know-how questions

I really don't know the syntax, even not how I have to search for. Take it easy — it is a programming question.

Guys, my bad. I already changed for integer. And @MatthewRiches, I don't understand your question. — Guilherme Oderdenge

@GuilhermeOderdenge: Phone numbers are not integers. If you can't add it, it isn't a number. You should only use strings. — SLaks

Use contactPhone.replace(/(\d{4})(\d{4})/, '$1 $2')

It will split the phone number into two groups, with 4 digits each.

If contactPhone is a number and not a string, you can use contactPhone.toString() before using the regex replace.

Hello, @dcro. Your answer is concisely and clear — thank you! And about the confusion about the type of my variable, don't worry because was my mistake. I've expressed myself badly.

You could simply;

var formatted = contactPhone.toString();
formatted = formatted.substr(0, 4) + " " + formatted.substr(4);

try this:

function sep(str){
    var len = str.length;
    var a = len/2;
    return str.substring(0, a) + ' ' + str.substring(a, len);
}

If you wanted to be more robust, you could add a space after every 4th character?

contactPhone.replace(/.{1,4}/g, '$& ');

Does this help?

function splitInTwo(s){
    return [s.substring(0, s.length/2), s.substring(s.length/2)]
}
