    用i标签代替input标签，具体把input标签隐藏，设置i标签的样式。具体图标可放在i的里面，点击时利用input的伪类:checked+i>..{}改变点击时的状态。

js:

<script src="../js/jquery.js"></script>
<script>
    $(function(){
        $(function(){
            $("input[type='checkbox']").click(function(){
                if($(this).is(':checked') != undefined) {//判断当前复选框是否被选中，因为如果复选框没有被选中attr()函数的返回值是undefined，如果选中的话返回值checked。
                    //alert(0);
                    $(this).parent("label").siblings().find("input").attr("checked",false);
                    $(this).attr("checked",true);
                }
            });
        });
    });
</script>
