Javascript平面图理解？

Question

我不熟悉 Javascript，但我试图从本质上对以下内容进行平面映射:

我看到 (5) [Array(2), Array(2), Array(2), Array(2), Array(2)] 的地方 我想看起来像其他人都分开了。

0
:
(5) [Array(2), Array(2), Array(2), Array(2), Array(2)]

:
(2) [-112.2550785337791, 36.07954952145647]

我有以下代码:

let parsedGeoCoords = _.flatten(aoiList.map((aoi) => {
  return terraformer.parse(aoi.geo).coordinates
}), true)

新尝试？凌乱

let data = [
  [["1", "3"],["2", "5"],["3", "7"]],
  ["4", "5"],
  ["5", "56"]
]
function flatten(arr) {
  return arr.reduce(function (flat, toFlatten) {
    return flat.concat(is2DArray(toFlatten) ? (toFlatten) : [(toFlatten)]);
  }, []);
}

function is2DArray(arr) {
  return Array.isArray(arr[0])
}

console.log(flatten(data))

输入数据

let data = [
  [["1", "3"],["2",3],["3","5"]],
  ["4", "5"],
  ["5", "56"],
  "4",
  "7"
]

欲望

[ [ '1', '3' ],
  [ '2', 3 ],
  [ '3', '5' ],
  [ '4', '5' ],
  [ '5', '56' ],
  [ '4', '7' ] ]

Answer 1

您可以只修改当前输出以匹配您想要的。只需添加:

var fullFlatten = _.flatten(_.map(data, function(elem) {
   return _.flatten(elem);
}));
var chunks = _.chunk(fullFlatten, 2);
