function jqchk(){ //jquery获取复选框值

            }
        });

    }

}

mapper里的sql

<delete id="deleteByIds" parameterType="String">
    delete from t_house where id in(${id})
    
</delete>

controller里

@RequestMapping(value = "/todelete.action",method = RequestMethod.POST)
@ResponseBody
public Map<String,Object> todelete(String ids){
    Map<String, Object> map = new HashMap<>();
    System.out.println(ids+"--------------------------");
    iHouseService.deleteByIds(ids);

    map.put("flag",1);


    return map;

}
