the requirement now is to know how to traverse the id of the selected node to make the selected node "selected": the selected attribute of false is true
. What else to do with combing 
var data = [
  {
    id: '00',
    text: '',
    state: {
      selected: false,
    },
  },
  {
    id: '01',
    text: '',
    children: [
      {
        id: '0101',
        text: '',
        state: {
          selected: false,
        },
      },
      {
        id: '0102',
        text: '',
        state: {
          selected: false,
        },
      },
    ],
  },
]

var selected = ['00', '0101']

var iterative = (data, callback) => {
  if (Array.isArray(data)) {
    data.forEach(item => {
      if (item.children && item.children.length) {
        iterative(item.children, callback)
      }
      callback(item)
    })
    return
  }
  callback(data)
}

iterative(data, item => {
  if (selected.includes(item.id)) {
    item.state.selected = !item.state.selected
  }
})
console.log(data)

Previous: A strange phenomenon that occurs when using setTimeout (fn, 0)

Next: I want to teach myself the background management system to manage the foreground data.
