用递归函数遍历判断同一层级某个属性值是否相同

 checkForm(data) {
      let name = {};
      let isCheck = false;
      function irCheckForm(data, j = 0) {
        if (data && data.length) {
          let len = data.length;
          name[j] = "";
          for (let i = 0; i < len; i++) {
            let item = data[i];
            if (!name[j]) {
              name[j] = [];
            }
            if (name[j].includes(data[i].fieldName)) {
              isCheck = true;
            } else {
              name[j].push(data[i].fieldName);
            }
            if (item.childList && item.childList.length) {
              irCheckForm(item.childList, j + "" + i);
            }
          }
        }
      }
      irCheckForm(data);
      if (isCheck == true) {
        this.indisplay = true;
      } else {
        this.indisplay = false;
      }
    },```
