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    })
