當后端返回的數(shù)據(jù)中嵌套了一層數(shù)據(jù)，此時，你需要將數(shù)據(jù)內(nèi)容為null的清除是

      function Func(obj = data) {//obj就等于后端返回的數(shù)據(jù)
        Object.keys(obj).forEach((key) => {
          console.log(111, key);
          let isObj = Object.prototype.toString.call(obj[key]);//判斷數(shù)據(jù)類型
          console.log("isObj", isObj);
          if (isObj === "[object Null]") {//如果數(shù)據(jù)類型為null則刪除
            delete obj[key];
          } else if (isObj === "[object Object]") {
            Func(obj[key]);
          }
        });
      }
      Func(data);//后端數(shù)據(jù)傳入
