您需要检查 td 是否具有输入类型 radio 并检查它然后获取值，如果不是 radio 则获取文本。

$(".hit").click(function(){   
var $row = $('table').find('tr:first');
var th=[];
$.each($row.find('th'),
function (index) {	
th[index]=$(this).text();
});
 var str="";var counter=0;var headCounter=th.length;
 $.each($("input[name^='flight']:checked").closest("tr").find('td'),
         function (index) {		   
    if($(this).find('input:radio').length && $(this).find('input:radio').is(':checked')){
     if(counter != 0 )
    str +="&";
   str +="id"+(counter+1)+"=" +  $(this).find('input:radio').val();
   counter++;
 // adding Th here  
    str +="&";
   str +="id"+(counter+1)+"=" +  th[index%headCounter];
   counter++;
    }
    if($(this).find('input:radio').length == 0){
     if(counter != 0 )
    str +="&";
	       str +="id"+(counter+1)+"=" + $(this).text();
      counter++;
      }   });
console.log(str);
//location.href = "guestdetails.php?" + str;
});
