javascript - 这样的对象怎么变成数组或者指定的对象格式?

供参考

function getArr (data) {
  function compare (a, b) {
    return Number(a) - Number(b)
  }

  return Object.keys(data)
    .filter(k => data[k] !== false)
    .sort(compare)
    .reduce((arr, k) => {
      arr.push(Number(k))
      var value = result[k]
 
      if (typeof value === 'string') { arr.push(Number(value)) }
      else if (typeof value === 'object' && value !== null) {
        arr = arr.concat(Object.keys(value).filter(k => value[k]).sort(compare).map(k => Number(k)))
      }
      return arr
    }, [])
}

function transform (data) {
    let result = []
    Object.keys(data)
        .forEach(key => {
            let values, value = data[key]
            if (typeof value === 'object')
                values = Object.keys(value).filter(k => value[k])
            else
                values = [value]
            if (values.length)
                result.push([key].concat(values))
        })
    return result
}

JSON.stringify(result)
    .replace(/"/g, '')
    .replace(/}/g, ',}')
    .replace(/\d+:false,/g, '')
    .replace(/:true,/g, ':')
    .replace(/{|}/g, '')
    .replace(/:,/g, ',')
    .replace(/,$/, '')
    .split(',')

// [ '2:3', '3:4:5', '8:16', '9:20' ]
