推荐答案

试试这样的:

$(function(){
  $('input[type="radio"]').click(function(){
    if ($(this).is(':checked'))
    {
      alert($(this).val());
    }
  });
});

如果你给你的单选按钮一个类，那么你可以用 $('.someclass') 替换代码 $('input[type="radio"]')代码>.

If you give your radio buttons a class then you can replace the code $('input[type="radio"]') with $('.someclass').
