我給了該表的ID以使其位於頁面的特定部分。

Live Demo

$('#btn').click(function() { 
    validationSuccess = true; 
    $('#tbl tr td:nth-child(1)').each(function() { 
     var group = $(this).text(); 
     if ($('[name=' + group + ']:checked').length == 0) { 
      alert(group + "is not selected"); 
      validationSuccess = false; 
     } 
    }); 
    if(validationSuccess) 
    { 
     alert("Validation successful"); 
    } 
});​
