Answer 1

if (!$(":checkbox[id^=chkBox]:checked").length) {
    alert('Please select atleast one checkBox');
    return false;
}
alert('you filled at least one!');
return true;

Since all of your checkbox IDs start with ‘chkBox’ you can address them using the attribute Starts With selector. A truthy length of checked checkboxes means at least one has been checked.
