JQ中click事件在ie上无效，火狐，谷歌，360都正常

  $('input:radio').bind("click", function () {
        //               alert("11");
        var cs = $(this).attr('class').toString();
        var a = $(this).attr('id').toString();
        var c = cs.substring(0, 4);
        //             alert("22");
        if (c == "yxdk") {
            $('#cardNo').show();
            $('#cardPwd').show();
        }
        else {
            $('#cardNo').hide();
            $('#cardPwd').hide();
        }
        if (a == "dkc") {
            $('#option_01').addClass('card');
        }
        else {
            $('#option_01').removeClass('card');
        }
        var ck = $(this).attr('checked');
        if (ck == "checked") {
            var id = $(this).attr('id').toString();
            $("#types").val(id);
        }
    });
        -------------
        html代码
#       <div id="sj" style=" margin-top:10px;" >
                                    <p style="color:White; padding-left: 8px;display: block;width: 96px;height: 24px;line-height: 24px;background-image: url(../../Images/pane.png);margin-bottom: 5px;margin-left: -8px;">充值卡支付</p>
                                     <input type="radio" id="zhilt" name="rtype" class="yxdk rad" value="LT">
                                    <label name="zhilt" class="label1" for="zhilt">联通卡充值</label>
                                    <input type="radio" id="zhidx" name="rtype" class="yxdk rad" value="DX" >
                                    <label name="zhidx" class="label1" for="zhidx">电信卡充值</label>
                                    <input type="radio" id="zhisz" name="rtype" class="yxdk rad" value="SZ" >
                                    <label name="zhisz" class="label1" for="zhisz">移动卡充值</label>
                                    </div>

ie不支持bind你换成onclick事件吧

jquery倒入没有，代码要放到html代码下面或者dom ready中，还有其他的代码在哪里？cardNo，cardPwd

 <div id="sj" style=" margin-top:10px;" >
                                    <p style="color:White; padding-left: 8px;display: block;width: 96px;height: 24px;line-

height: 24px;background-image: url(../../Images/pane.png);margin-bottom: 5px;margin-left: -8px;">充值卡支付</p>
                                     <input type="radio" id="zhilt" name="rtype" class="yxdk rad" value="LT">
                                    <label name="zhilt" class="label1" for="zhilt">联通卡充值</label>
                                    <input type="radio" id="zhidx" name="rtype" class="yxdk rad" value="DX" >
                                    <label name="zhidx" class="label1" for="zhidx">电信卡充值</label>
                                    <input type="radio" id="zhisz" name="rtype" class="yxdk rad" value="SZ" >
                                    <label name="zhisz" class="label1" for="zhisz">移动卡充值</label>
                                    </div>
