对的

下面为后台传递过来的json数据

{
   data: {
      pager: {
         pageSize: 15,
         page: 1,
         count: 2,
         entities: [{
            pk_memberinfo: "98a23171c66c4d93b86f64d3cf8f8274",
            mem_number: "100010",
            mem_name: "罗晨月",
            mem_sex: "1",
            mem_age: "5",
            mem_telephone: "13910871920",
            mem_starttime: "2018-01-10",
            mem_endtime: "2019-01-09",
            mem_enable: "0",
            pk_membertype: "2d5384597f3e41f7b2d8bbfc017f2367",
            ts: "2018-01-09 11:00:44",
            createUser: "",
            dr: false,
            id: 2
         }, {
            pk_memberinfo: "0541e29552dd4905b2fd67a6a0533559",
            mem_number: "10009",
            mem_name: "元祖",
            mem_sex: "0",
            mem_age: "4",
            mem_telephone: "13801013043",
            mem_starttime: "2018-01-09",
            mem_endtime: "2019-01-08",
            mem_enable: "0",
            pk_membertype: "a2996a9156ee4c93a74c9e2cc600cc30",
            ts: "2018-01-09 10:40:18",
            createUser: "",
            dr: false,
            id: 1
         }],
         url: "/thunder-web/member/list?page=",
         simplePager: false,
         maxLength: 1
      },
      sexmap: {
         "0": "男",
         "1": "女"
      },
      "0": "男",
      "1": "女"
   },
   operationState: "SUCCESS"
}

我想获取sexmap这个数据。因为列表数据中的性别我存的是单独的数字 要转成中文显示。

模板贴一下看看

我想 在下面的代码中进行获取map

<td>${member.mem_sex!}</td>

看上去没写错的样子，是后台报错了吗？

我的意思是怎么把 下面的 sexmap: {
"0": "男",
"1": "女"
},取出来

{
   data: {
      pager: {
         pageSize: 15,
         page: 1,
         count: 2,
         entities: [{
            pk_memberinfo: "98a23171c66c4d93b86f64d3cf8f8274",
            mem_number: "100010",
            mem_name: "罗晨月",
            mem_sex: "1",
            mem_age: "5",
            mem_telephone: "13910871920",
            mem_starttime: "2018-01-10",
            mem_endtime: "2019-01-09",
            mem_enable: "0",
            pk_membertype: "2d5384597f3e41f7b2d8bbfc017f2367",
            ts: "2018-01-09 11:00:44",
            createUser: "",
            dr: false,
            id: 2
         }, {
            pk_memberinfo: "0541e29552dd4905b2fd67a6a0533559",
            mem_number: "10009",
            mem_name: "元祖",
            mem_sex: "0",
            mem_age: "4",
            mem_telephone: "13801013043",
            mem_starttime: "2018-01-09",
            mem_endtime: "2019-01-08",
            mem_enable: "0",
            pk_membertype: "a2996a9156ee4c93a74c9e2cc600cc30",
            ts: "2018-01-09 10:40:18",
            createUser: "",
            dr: false,
            id: 1
         }],
         url: "/thunder-web/member/list?page=",
         simplePager: false,
         maxLength: 1
      },
      sexmap: {
         "0": "男",
         "1": "女"
      },
      "0": "男",
      "1": "女"
   },
   operationState: "SUCCESS"
}

那你不是已经写了吗？

这块不行 ${member.mem_sex!} 我写成${obj.data.sexmap.get(member.mem_sex!)} 这样就报错

不行是什么意思，没有显示出来还是怎样

${obj.data.sexmap[member.mem_sex]}

${obj.data.sexmap[member.mem_sex]} 这么写${obj.data.sexmap(member.mem_sex)} 都报上面的错误

去掉get啊

@admin 谢谢 就是你说的问题，解决了。
