With some special format? You must write a phone number?.... Tell your cases. — Andynedine, Mar 12 '14 at 08:13

Here are some regular expression formats :

Phone Number (Format: +99(99)9999-9999) - [\+]\d{2}[\(]\d{2}[\)]\d{4}[\-]\d{4}  
UK Phone Number - ^\s*\(?(020[7,8]{1}\)?[ ]?[1-9]{1}[0-9{2}[ ]?[0-9]{4})|(0[1-8]{1}[0-9]{3}\)?[ ]?[1-9]{1}[0-9]{2}[ ]?[0-9]{3})\s*$  
USA Phone Number -  US based Phone Number in the format of: 123-456-7890 - \d{3}[\-]\d{3}[\-]\d{4}

var data = yourdata;
var re = /^\d{10}$/;    //user regular expression (this example is used to check 
                        // validation for 10 numbers or digits).
var a = data.match(re);
if(a == null)
{

   //show error message

}
else
{
   //no error
}

Use regular expression
Format of Phone numbers and landline numbers will change based on country

A simple case:

<script type="text/javascript">  
      var reg = /^\d{10}$/;  
      function PhoneValidation(phoneNumber)
      {  
        return reg.test(phoneNumber);
      }  
</script>

Try this:

function checkForNumber(number, size) {
    var nbrString = '';
    for (var i = 0; i < number.length; i++) {
        var cc = number.charCodeAt(i);
        if (cc >= 48 && cc < 58) {
            nbrString += number[i];
        }
    }
    return nbrString.length === size;
}

Usage:

var paramA = "012 345 67 89";
var paramB = 10;
checkForNumber(paramA, paramB);

paramA: your number to check in string format

paramB: the size of the number digits (normally it's 10)

You can modify the return parameter in the 'checkForNumber' function to fit your needs.

Here is an example on JSFiddle.
