I am in the process of learning JQuery thanks mostly to the positive reference here on Stack Overflow. I need a function that checks all the checkboxes in an element which have the same CSS class. It should returns true if at least one of them is checked. There are also other boxes in the element that are irrelevant to the check.

The CSS class is unnecessary and only in place to create a way to identify the checkboxes in the group. It feels like bad practice, so any recommendations about other ways to identify them are welcome.
