  Hi,

  write this code in click event

  function Validate()
  {
    var x = document.getElementById("txtPhomenumber").value;
    if(isNaN(x)|| x.indexOf(" ")!=-1)
    {
       alert("Enter numeric value");
       return false;
    }
    if (x.length > 10 || x.length > 8 )
    {
       alert("enter 10 or 8 characters");
       return false;
    }
    if (x.charAt(0)!="9" || x.charAt(0)!="2")
    {
        alert("it should start with 9 or 2 ");
        return false;
    }
  }

  all countries have Different types of writing method of Telephone Numbers and Mobile Numbers

  Like UnitedStates : 408-555-1212

  In Pakistan : 0333-3333333 OR 0213-3333333

  So, I think you should Defind which format you want? or you can Allow only Numeric character.. not ABCDEF,

  you can Allow Numeric character with lenght of Phone Number Like 11 or 10 etc.
