    /\d\.\d*\./

    - Change '*' to '+' if you don't want to match two consecutive dots
    - Change '\d' to '.' if you want to match any character rather than just digits.

var string="abc.123.xyz";
var array=string.split(".");
var length=array.length;
if(length==2)
   {
   //dot occurs ONCE
   }
else
   {
   //0 or more than 1 time
   }
    Code (JAVASCRIPT):
