filterTreeData(treelikeData, filterFunc, [options])

说明

该方法类似原生的 filter

当父节点不满足时，子节点即使满足也会被筛选掉

参数

treelikeData(Array): 树形数据

filterFunc(Function): 同原生 filter

[options](Object): 配置项

[options.childrenKeyName='children'](String): 子数据的 key，默认为'children'

返回值

treelikeData(Array): 树形数据

使用

const treeData = [
  { id: '1', title: '1', hasPermission: true },
  { id: '2', title: '2' },
  {
    id: '3',
    title: '3',
    hasPermission: true,
    children: [
      { id: '3-1', title: '3-1' },
      { id: '3-2', title: '3-2', hasPermission: true },
      { id: '3-3', title: '3-3', hasPermission: false },
    ],
  },
  {
    id: '4',
    title: '4',
    hasPermission: false,
    children: [
      { id: '4-1', title: '4-1' },
      { id: '4-2', title: '4-2', hasPermission: true },
    ],
  },
]
filterTreeData(treeData, (node) => node.hasPermission)
