如何强制复选框的行为像radiobutton，双循环

Question

I have checkboxes in 2 for loops. I want to force them to behave like radiobuttons. There should be only one option chosen for each Q (first loop). I have a peace of code, but it doesn't work. How to change it?

script type="text/javascript">  

    var classes = $('.myDiv').map(function () {
        return $(this).attr('class');
    }).get();

    $.each(classes, function(i) {
        $(classes[i]).change(function() {
            var checked = $(this).is(':checked');
            $(classes[i]).prop('checked',false);
            if(checked[i]) {
                $(this).prop('checked',true);
            }
        });
    });

Add a common class to the checkbox input and then use that class like below

 $("input:checkbox").change(function() { $(this).siblings().prop('checked', false); $(this).prop('checked', true); }); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <table> <tr> <td> <input type="checkbox" value="1" /> <input type="checkbox" value="1" /> <input type="checkbox" value="1" /> </td> </tr> <tr> <td> <input type="checkbox" value="1" /> <input type="checkbox" value="1" /> <input type="checkbox" value="1" /> </td> </tr> </table>
