关于javascript:递归-js递归改所有node里面属性名字

1. 递归拿出不是叶子结点的 id 数组

getPriv(this.roleId).then((response) => {
             const privData = this.privData
             var a = []
             var forfn = function (list) {for (var i = 0; i < list.length; i++) {if (list[i].children) {a.push(list[i].id)
                   forfn(list[i].children)
                 }
               }
             }
             forfn(privData)
            // 比对 a 和 b this.privIds 为在 b 数组中去除 a 数组蕴含的元素后造成的数组
             var b = response.data
             let RemoveSame = [...new Set([...a, ...b])]
             let SamePart = a.filter((item) => b.includes(item))
             let Difference = RemoveSame.filter((item) => !SamePart.includes(item)
             )
             this.privIds = Difference
             // this.$refs.menu.setCheckedNodes(response.data)
           })

2. 递归改所有 node 外面属性名字

getTree().then((response) => {this.menuOptions = []
      //data 为须要批改的 tree，这里次要是为 antd design 外面 select 标准数据

      const ass = (data) => {let item = []
        data.map((list, i) => {let newData = {}
          newData.title = list.label
          newData.id = list.id
          newData.parentId = list.parentId
          newData.children = list.children ? ass(children) : [] // 如果还有子集，就再次调用本人
          item.push(newData)
        })
        return item
      }
      var rda = ass(response.data)

      this.menuOptions = rda
    })
