数组对象中增加属性

this.folderList.forEach((item, index) => {
            item.OnlyKey = item.id + item.lve;
            if (item.childRndTree != null) {
              item.childRndTree.forEach((item2) => {
                item2.OnlyKey = item2.id + item2.lve;
                if (item2.childRndTree != null) {
                  item2.childRndTree.forEach((item3) => {
                    item3.OnlyKey = item3.id + item3.lve;
                  });
                }
              });
            }
          });

2/遍历JSON类型的数据 树形数据

this.getWpTreeCode(this.getWpDefaultArr);
getWpTreeCode(datas) {
      //遍历树
      // console.log("我是datasaasdasdasd",datas);
      for (var i in datas) {
        if (datas[i].subMenus != null) {
          this.getWpTreeCode(datas[i].subMenus);
        } else {
          this.wpdefaultArr.push(datas[i].code);
        }
        this.wpdefaultArr.push(datas[i].code);
      }
      console.log(this.wpdefaultArr);
    },
