文本文件格式如下：北京 2河北 3河北-邯鄲 301河北-保定 302河北-邢臺(tái) 303山東 4山東-青島 401山東-煙臺(tái) 402轉(zhuǎn)換成類似如下的json，我只要該結(jié)果const treeData = [{ label: '河北', value: '3', key: '3', children: [{ label: '邯鄲', value: '301', key: '302', }, { label: '保定', value: '302', key: '302', }], }]

沒做容錯(cuò), 格式必須按上面的格式

var str = `北京 2河北 3河北-邯鄲 301河北-保定 302河北-邢臺(tái) 303山東 4山東-青島 401山東-煙臺(tái) 402`;var arrStr = str.split("\n");var result = [];
arrStr.map(i => {  let = item = i.split(" ");  if (i.indexOf("-") == -1) {
    result.push({      label: item[0],
      value: item[1],      key: item[1],
      children: []
    })
  } else {    let city = item[0].split("-");    let cur = result.find(j => j.label == city[0])
    cur.children.push({      label: city[1],
      value: item[1],      key: item[1],
    })
  }
})
console.log(result)
console.log(JSON.stringify(result))

[
{"label":"北京","value":"2","key":"2","children":[]},
{"label":"河北","value":"3","key":"3","children":[
    {"label":"邯鄲","value":"301","key":"301"},
    {"label":"保定","value":"302","key":"302"},
