Basically its an availability schedule calendar.
Seven checkboxes has the same class. Then other seven boxes has the same class. There are total of 49 checkboxes and total 7 classes. So I want these checkboxes to behave like radio buttons. i.e No two checkboxes of same class can be checked at a time. For example, If someone checks the box with class 'earlyMorning' . When he checks the other checkbox with the same class the first one should be unchecked. Here is my html. Right now writing only 21 checkboxes.

<table> <tr>

            <th>Early Morning<br /><small>6am-9am</small></th>

                <td><input type=checkbox class=earlyMorning name=field_807[] id=field_871_0 value=Early Morning 6am-9am Monday style=display: none;></td>

I have found a nice example here but its not working in my case.
make checkbox behave like radio buttons with javascript

Based on the above tutorial, I tried this but not working

$(.earlyMorning).each(function()

{

    $(this).change(function()

    {

        $(.earlyMorning).prop('checked',false);

        $(this).prop('checked',true);

    });

});
