创建同名字兄弟节点覆盖

[chengandguo]

如果子节点包含field_2, 创建兄弟节点需要从3开始
`一种可能得修复方法
getRandomName(propertiesData) {
const currentField = "field_" + fieldNum++;
for (const key in propertiesData) {

    }
  }
}
utils.setData(state.data, keys, newPropertiesData);
// add required
parentKeys.push("required");
utils.setData(state.data, parentKeys, requiredData);
