[Solved] Jquery – Split a string(credit card number) in 4 groups [duplicate]

by


With simple logic

'4111111111111111'.match(/.{1,4}/g)

Other way

var str="4111111111111111";

var parts = [];    
for (var i = 0; i < str.length; i += 4) {
    parts.push(str.substring(i, i + 4));
}    
console.log(parts);
