I'm a little unclear if you want to validate that there's a comma after every 10 digits, or insert one automaticallyMichael Mrozek– Michael Mrozek2010-06-03 06:09:48 +00:00Commented Jun 3, 2010 at 6:09

@Hari kanna,
/(\d{10})/ is a regular expressions, with 10 continuous digits, and $1 means, matched 10 digits in the bracket ( 10 digits ), add comma after all matched instances. Basically, replacing 10 digits with 10 digits + ","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 commafyPhone(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=commafyPhone(this.value);"
However, my solution requires to remove the comma on your last number entered.
