jquery处理checkbox

1.控制checkbo只能选择其中一项

想用radiobox做单选题的选项，但是为了便于取值要用服务器空间，带来的麻烦就是不能使用name属性控制他们属于同一个域，现在使用checkbox+js的方式来实现radiobox的效果。

html代码：

<li class="liStyle">
    1.&nbsp;&nbsp;阿斯顿按时<label class="fillTims" style="display: none" id="selectTips">请选择</label>
    <!--begin选项-->
    <ul>
        
                <li class="liStyle2">
                    <span id="labOption">A         </span>.阿萨德发<input type="hidden" value="1" id="hidID" name="repSingle$ctl00$repSingleChoices$ctl00$hidID">
                    <input type="checkbox" name="repSingle$ctl00$repSingleChoices$ctl00$cheSingleChoice" id="cheSingleChoice"></li>
            
                <li class="liStyle2">
                    <span id="labOption">B         </span>.阿萨德发<input type="hidden" value="2" id="hidID" name="repSingle$ctl00$repSingleChoices$ctl01$hidID">
                    <input type="checkbox" name="repSingle$ctl00$repSingleChoices$ctl01$cheSingleChoice" id="cheSingleChoice"></li>
            
                <li class="liStyle2">
                    <span id="labOption">C         </span>.阿斯顿<input type="hidden" value="3" id="hidID" name="repSingle$ctl00$repSingleChoices$ctl02$hidID">
                    <input type="checkbox" name="repSingle$ctl00$repSingleChoices$ctl02$cheSingleChoice" id="cheSingleChoice"></li>
            
    </ul>
    <!--end选项-->
    <br>
</li>

js代码：

//fun1_1 单选题只能选中选项其一
function mutipleCheckAction() {
    $("ul#ulSingle>li.liStyle>ul>li.liStyle2>:checkbox").click(function () {
        var count = $("ul#ulSingle>li.liStyle>ul>li.liStyle2>:checkbox").length;
        for (var i = 0; i < count; i++) {
            $("ul#ulSingle>li.liStyle>ul>li.liStyle2>:checkbox:eq(" + i + ")").attr("checked", false)
        }
        $(this).attr("checked", true);
    })
}

            // 全选
            $("#btnCheckAll").bind("click", function () {
                $("[name = chkItem]:checkbox").attr("checked", true);
            });
            // 全不选
            $("#btnCheckNone").bind("click", function () {
                $("[name = chkItem]:checkbox").attr("checked", false);
            });
            // 反选
            $("#btnCheckReverse").bind("click", function () {
                $("[name = chkItem]:checkbox").each(function () {
                    $(this).attr("checked", !$(this).attr("checked"));
                });
            });
            // 全不选
            $("#btnSubmit").bind("click", function () {
                var result = new Array();
                $("[name = chkItem]:checkbox").each(function () {
                    if ($(this).is(":checked")) {
                        result.push($(this).attr("value"));
                    }
                });
                alert(result.join(","));
            });
        });

    <script type="text/javascript">
        $(function () {
            // chkAll全选事件
            $("#chkAll").bind("click", function () {
                $("[name = chkItem]:checkbox").attr("checked", this.checked);
            });
            // chkItem事件
            $("[name = chkItem]:checkbox").bind("click", function () {
                var $chk = $("[name = chkItem]:checkbox");
                $("#chkAll").attr("checked", $chk.length == $chk.filter(":checked").length);
            })
        });
    </script>
</head>
<body>
    <table id="tb">
