签名

renameTreeKeys({ tree, mapping={}, childrenKey='children', childrenKeyOut })

引入

import { renameTreeKeys } from 'flit-kit'

参数

参数	类型	默认值	说明
`tree`	`Array<object>`	`[]`	输入树
`mapping`	`Record<string,string>`	`{}`	普通属性名映射，如 `{ id:'code' }`
`childrenKey`	`string`	`'children'`	输入树的子节点字段名
`childrenKeyOut`	`string`	`undefined`	输出树的子节点字段名，如 `'childrenList'`

示例

const src = [
  { id: 1, name: 'A', children: [ { id: 2, name: 'A-1' } ] }
]
const out = renameTreeKeys({
  tree: src,
  mapping: { id: 'code', name: 'label' },
  childrenKey: 'children',
  childrenKeyOut: 'childrenList',
})

复杂度

O(n·k)
