Question

I want validation on text box for phone number which allowed

Allowed chars:

space + ( ) - 0-9

(or + can be first char after trim, like ([phone] or [phone])

Length: min 8, max 16.

Please help.

I have tried but I am not able to get correct Regex.

function phNum(val) {

var subjectString = val;
var regexObj = /^\(?([0-9][- ]{3})\)?[-. ]?([0-9]{3})[-. ]?([0-9]{3})$/;

if (regexObj.test(subjectString)) {
var formattedPhoneNumber = subjectString.replace(regexObj, “+61$1$2$3”);

document.getElementById(‘a’).value = formattedPhoneNumber;
}
}

get a regex for your needs

http://regexlib.com/DisplayPatterns.aspx?cattabindex=6&categoryId=7&AspxAutoDetectCookieSupport=1

var regex = new RegExp("sum regex");


if (input.val().match(regex))
{
   //true
}
else
{
  //false
}
