                            if(s!="")
                            {
                                 if(isNaN(s))
                                {

             var pattern =/^(([0\+]\d{2,3}-)?(0\d{2,3})-)(\d{7,8})(-(\d{3,}))?$/;
             //var pattern =/(^[0-9]{3,4}\-[0-9]{7,8}$)|(^[0-9]{7,8}$)|(^\([0-9]{3,4}\)[0-9]{3,8}$)|(^0{0,1}13[0-9]{9}$)/;
                 if(s!="")
