如何把后台的复选框值传给jsp页面？

1 StringBuffer s=new StringBuffer();
2         for (Muen muen : li) {
3             s.append(muen.getId()+",");
4         }
5         modelAndView.addObject("r", r);
6         modelAndView.addObject("roleinfo",s.toString());
7         modelAndView.setViewName("/role-edit.jsp");

1 <input type="hidden" value="${roleinfo }" id="rolehidden"/>

<script>
 var srole = $("#rolehidden").val();//接收隐藏域的值
 var myarray = srole.split(",");//用数组接收域名的值去除","                           
 $("input[type=‘checkbox‘]").each(function(){
         for(var t in myarray){//遍历数组
         if(myarray[t]==$(this).val()){    //如果复选框的value值正好是数组里的值，就用prop刷新“checked”状态                                   
                $(this).prop("checked","checked");
            break;
     }
          }
              });
</script>
