Sorry, the problem is with your regex, i missed that, change to this its fully working:

  var ck_password =  /^[A-Za-z0-9-]/;

            if(!ck_password.test(stringf))
            {

                alert("Family name can only contain alphanumeric characters and hypehns(-)")

            }

Console in chrome, go to the OPTIONS in the right top coner, select TOOLS, then DEVELOPER TOOLS.
