jsp获取后端传递的数据

mav.addObject("deanClassTypeArray", new ObjectMapper().writeValueAsString(deanClassTypeList)); // java后端向前端传递json字符串

var deanClassTypeStr = '${deanClassTypeArray }'; // 这样用ognl表达式获取数据
var deanCalssTypeMap = JSON.parse(deanClassTypeStr);

function deanCalssTypeFormatter(value, rowData, rowIndex) {
  if (value === undefined || value === '' || value === null) {
    return '';
  }
  for (var i = 0; i < deanCalssTypeMap.length; i++) {
    if (deanCalssTypeMap[i].typeId === value) {
      return deanCalssTypeMap[i].typeName;
    }
  }
}
