• I'm a little unclear if you want to validate that there's a ma after every 10 digits, or insert one automatically – Michael Mrozek Commented Jun 3, 2010 at 6:09

"242452354643663463636346366363463636365636363634656346".replace(/(\d{10})/g,"$1,")

// 2424523546,4366346363,6346366363,4636363656,3636363465,6346

Above solution did not help with splitting a 10 digit phone number being typed into for example a textarea. My solution: 1. your text area should be validated to return only numbers onKeyPress.

then

function mafyPhone(str){
    var newStr='';
    if(str.length>10){
        var str_array=str.split(",");
        for(var i = 0; i < str_array.length; i++) {
            newStr+=str_array[i].replace(/(\d{10})/g,'$1,');
        }
        return newStr;
    }
    return str;
}

On the textarea form field, i used:

onKeyUp="this.value=mafyPhone(this.value);"

However, my solution requires to remove the ma on your last number entered.
