直接上demo代碼

需要用到Lodash，應該前端都知道吧

const treeData = [
  {
    name: '1',
    id: '1',
    children: [
      {
        name: '1-1',
        id: '1-1'
      },
      {
        name: '1-2',
        id: '1-2',
        children: [
          {
            name: '1-2-1',
            id: '1-2-1'
          },
          {
            name: '1-2-2',
            id: '1-2-2',
            children: [
              {
                name: '1-2-2-1',
                id: '1-2-2-1',
              }
            ]
          },
        ]
      },
      {
        name: '1-3',
        id: '1-3',
        children: [
          {
            name: '1-3-1',
            id: '1-3-1'
          },
          {
            name: '1-3-2',
            id: '1-3-2'
          },
        ]
      }
    ]
  },
  {
    name: '2',
    id: '2',
    children: [
      {
        name: '2-1',
        id: '2-1',
      },
      {
        name: '2-2',
        id: '2-2',
      }
    ]
  }
]
const getTail = item => item.children && item.children.length > 0 ? item.children.map(m => getTail(m)) : [item]
const result = _.flattenDeep(treeData.map(m => getTail(m)))
console.log(' log result', result)
