后台传回来的Map类型的数据在前台中的JS代码中使用

        Map<String, String> projectTypeCodeMap = SysCodeUtils.getSysCodeMap(request, CommonFields.XT_PROJECT_TYPE);
        Map<String, String> projectRankCodeMap = SysCodeUtils.getSysCodeMap(request, CommonFields.XT_PROJECT_RANK);
        model.addAttribute("projectTypeMap", JSONObject.toJSON(projectTypeCodeMap));
        model.addAttribute("projectRankMap", JSONObject.toJSON(projectRankCodeMap));
        return "/pms/project_implement/suspend/list";

function formatProjectRank(cellValue, options, rowObject) {
        let map = JSON.parse('${projectRankMap}');
        let value = "";
        for(let item in map){
            if (cellValue === item){
                value = map[item];
            }
        }
        return value
    }

其中JSONObject是来自于alibba的fastjson
import com.alibaba.fastjson.JSONObject
在前台JS代码中使用时，
JSON.parse('${projectRankMap}')即可获取到对应的JSON数据。
