Answer 1

就酱？

let result = []
JSON.stringify(array, (k, v) => {
  if (k === 'pstaffs') result = result.concat(v)
  return v
});
result;

Answer 2

console.log('结果', getPstaffs([], data))

function getPstaffs (res, list) {
  for(var item, a = 0; a < list.length; a++) {
    item = list[a]
    if(getType(item.pstaffs) === 'Array') {
      res = res.concat(item.pstaffs)
    }
    if(getType(item.children) === 'Array') {
      res = getPstaffs(res, item.children)
    }
  }
  return res;
}

function getType (data) {
  return Object.prototype.toString.call(data).replace(/(.*\s)|.$/g, '');
}
