                        currentEle.attr("checked", true);

                    }else{

                        currentEle.attr("checked", false);

                    }

                    i++;

                });

                i = 0;

                $(".checkBox1").each(function(){

                    var currentEle = parentEle.children(".checkBox1:eq(" + i + ")");

                    alert(currentEle.attr("checked"));

                    i++;

                });

            });

        </script>

    </body>

</html>

这个是用来满足特殊需求的勾选一个单选按钮checked设置为true,其他的同name的单选框checked都设置为false.
