    $("#MwDataList input[name=selectRadioGroup]:checked").closest('tr');

    

    

    How to find the closest row?
    

    Using .closest():
    

    var $row = $(this).closest("tr");

    

    

    Using .parent():
    

    Check this .parent() method. This is alternative of a .prev() and .next().
    

    var $row = $(this).parent()             // Moves up from 

                  .parent();            // Moves up from  to 





var $row = $(this).closest("tr"),       // Finds the closest row 
 elements

$.each($tds, function() {               // Visits every single  element
    console.log($(this).text());        // Prints out the text within the 
});
