If you want at least one checkbox checked, you can use this

var somethingChecked = false;
$("input[type=checkbox]").each(function() {
  if(this).is(':checked')) {
    somethingChecked = true;
  }
});
if(!somethingChecked) {
  alert("You haven't checked anything yet");
}

What this does is initialize a variable to false. Then the script loops through all inputs of type checkbox. If the item is checked, set the variable to true. Finally, check if the variable is still false. If it is, then show an error.
