Js linq:按2个属性分组

jslinq group-by arrays javascript

NisuSan · 技术社区 · 8 年前

我有以下数组:

    var data = [
  {street: "ÐÐ°Ð»ÐµÐ½ÐºÐ°", house: "11", flats: "10,11,12,13,17,18,21,24,27,29,3,30,32,33,36,4,40", isNotApply: false},
  {street: "ÐÐ°Ð»ÐµÐ½ÐºÐ°", house: "3", flats: "1,12,14,15,16,19,2,21,23,24,28,29,3,30,31,32,6", isNotApply: true},
  {street: "ÐÑÑÐºÐµ", house: "110", flats: "0", isNotApply: true},
  {street: "ÐÐ°Ð´Ð¸Ð¼Ð° ÐÑÑÐ¾Ð²Ð°", house: "11", flats: "10,100,101,102,104,105", isNotApply: false},
  {street: "ÐÐ°Ð´Ð¸Ð¼Ð° ÐÑÑÐ¾Ð²Ð°", house: "120", flats: "0", isNotApply: true}
];

我使用GroupBy和这个nice得到了这个结果,但是我如何设置 不适用 作为这2个阵列的关键?

var data = [
  {street: "ÐÐ°Ð»ÐµÐ½ÐºÐ°", house: "11", flats: "10,11,12,13,17,18,21,24,27,29,3,30,32,33,36,4,40,4â¦6,58,61,64,65,67,68,69,7,70,71,73,75,76,78,8,80,9", isNotApply: false},
  {street: "ÐÐ°Ð»ÐµÐ½ÐºÐ°", house: "3", flats: "1,12,14,15,16,19,2,21,23,24,28,29,3,30,31,32,6", isNotApply: true},
  {street: "ÐÑÑÐºÐµ", house: "110", flats: "0", isNotApply: true},
  {street: "ÐÐ°Ð´Ð¸Ð¼Ð° ÐÑÑÐ¾Ð²Ð°", house: "11", flats: "10,100,101,102,104,105,106,107,109,110,111,112,113â¦73,75,76,79,8,81,82,83,85,86,88,90,91,94,95,96,99", isNotApply: false},
  {street: "ÐÐ°Ð´Ð¸Ð¼Ð° ÐÑÑÐ¾Ð²Ð°", house: "120", flats: "0", isNotApply: true}
];

result = Enumerable.From(data)
        .GroupBy(
            "{IsNotApply: $.isNotApply, House: $.house}",
            "{Street: $.street, House: $.house, Flats: $.flats}",
            "{ data: $$.ToArray(), isNotApply: $.IsNotApply }",
            "$.IsNotApply"
        )
        .ToArray();

console.log(result);

您可以添加一个函数来获取零件结果对象所需的键。

var data = [{ street: "ÐÐ°Ð»ÐµÐ½ÐºÐ°", house: "11", flats: "10,11,12,13,17,18,21,24,27,29,3,30,32,33,36,4,40,4â¦6,58,61,64,65,67,68,69,7,70,71,73,75,76,78,8,80,9", isNotApply: false }, { street: "ÐÐ°Ð»ÐµÐ½ÐºÐ°", house: "3", flats: "1,12,14,15,16,19,2,21,23,24,28,29,3,30,31,32,6", isNotApply: true }, { street: "ÐÑÑÐºÐµ", house: "110", flats: "0", isNotApply: true }, { street: "ÐÐ°Ð´Ð¸Ð¼Ð° ÐÑÑÐ¾Ð²Ð°", house: "11", flats: "10,100,101,102,104,105,106,107,109,110,111,112,113â¦73,75,76,79,8,81,82,83,85,86,88,90,91,94,95,96,99", isNotApply: false }, { street: "ÐÐ°Ð´Ð¸Ð¼Ð° ÐÑÑÐ¾Ð²Ð°", house: "120", flats: "0", isNotApply: true }],
    result = Enumerable
        .From(data)
        .GroupBy(
            "$.isNotApply",
            "{ Street: $.street, House: $.house, Flats: $.flats }",
            "(k, v) => ({ [k]: v.ToArray() })"
        )
        .ToArray();

console.log(result);

.as-console-wrapper { max-height: 100% !important; top: 0; }

添加了两个的代码段 JS公司 和 Linq公司 .

var data = [
  {street: "ÐÐ°Ð»ÐµÐ½ÐºÐ°", house: "11", flats: "10,11,12,13,17,18,21,24,27,29,3,30,32,33,36,4,40,4â¦6,58,61,64,65,67,68,69,7,70,71,73,75,76,78,8,80,9", isNotApply: false},
