It makes your unchecked checkboxes show up in the $_POST on the server.
It’s very simple and doesn’t need javascript.

<input type="hidden" name="box1" value="0" />
<input type="checkbox" name="box1" value="1" />

If the checkbox is not checked then the value of the hidden input is submited, else the value of the checkbox.
