我有一个对象数组，其中关键“时间”包含ISO格式的日期

示例- 2021-12-24T11:02:20.370705

arr.sort(function(a,b){return a.time > b.time ? 1 : a.time < b.time ? -1 : 0 });

上面的工作对我来说就像一个魅力!

这是解决你的问题的最短方法。

  var array = [{id: 1, date: 'Mar 12 2012 10:00:00 AM'}, {id: 2, date: 'Mar 8 2012 08:00:00 AM'}];

  var sortedArray = array.sort((a,b) => Date.parse(new Date(a.date)) - Date.parse(new Date(b.date)));

在纠正JSON之后，这应该为你工作了:

var array = [{id: 1, date:'Mar 12 2012 10:00:00 AM'}, {id: 2, date:'Mar 8 2012 08:00:00 AM'}];


array.sort(function(a, b) {
    var c = new Date(a.date);
    var d = new Date(b.date);
    return c-d;
});

我推荐GitHub: Array sortBy - sortBy方法的最佳实现，它使用施瓦茨变换

但是现在我们将尝试这种方法。 让我们创建一个方法来排序数组，它能够按某些属性排列对象。

创建排序函数

var sortBy = (function () {
  var toString = Object.prototype.toString,
      // default parser function
      parse = function (x) { return x; },
      // gets the item to be sorted
      getItem = function (x) {
        var isObject = x != null && typeof x === "object";
        var isProp = isObject && this.prop in x;
        return this.parser(isProp ? x[this.prop] : x);
      };
      
  /**
   * Sorts an array of elements.
   *
   * @param {Array} array: the collection to sort
   * @param {Object} cfg: the configuration options
   * @property {String}   cfg.prop: property name (if it is an Array of objects)
   * @property {Boolean}  cfg.desc: determines whether the sort is descending
   * @property {Function} cfg.parser: function to parse the items to expected type
   * @return {Array}
   */
  return function sortby (array, cfg) {
    if (!(array instanceof Array && array.length)) return [];
    if (toString.call(cfg) !== "[object Object]") cfg = {};
    if (typeof cfg.parser !== "function") cfg.parser = parse;
    cfg.desc = !!cfg.desc ? -1 : 1;
    return array.sort(function (a, b) {
      a = getItem.call(cfg, a);
      b = getItem.call(cfg, b);
      return cfg.desc * (a < b ? -1 : +(a > b));
    });
  };
  
}());

设置无序数据

var data = [
  {date: "2011-11-14T17:25:45Z", quantity: 2, total: 200, tip: 0,   type: "cash"},
  {date: "2011-11-14T16:28:54Z", quantity: 1, total: 300, tip: 200, type: "visa"},
  {date: "2011-11-14T16:30:43Z", quantity: 2, total: 90,  tip: 0,   type: "tab"},
  {date: "2011-11-14T17:22:59Z", quantity: 2, total: 90,  tip: 0,   type: "tab"},
  {date: "2011-11-14T16:53:41Z", quantity: 2, total: 90,  tip: 0,   type: "tab"},
  {date: "2011-11-14T16:48:46Z", quantity: 2, total: 90,  tip: 0,   type: "tab"},
  {date: "2011-11-31T17:29:52Z", quantity: 1, total: 200, tip: 100, type: "visa"},
  {date: "2011-11-01T16:17:54Z", quantity: 2, total: 190, tip: 100, type: "tab"},
  {date: "2011-11-14T16:58:03Z", quantity: 2, total: 90,  tip: 0,   type: "tab"},
  {date: "2011-11-14T16:20:19Z", quantity: 2, total: 190, tip: 100, type: "tab"},
  {date: "2011-11-14T17:07:21Z", quantity: 2, total: 90,  tip: 0,   type: "tab"},
  {date: "2011-11-14T16:54:06Z", quantity: 1, total: 100, tip: 0,   type: "cash"}
];

使用它

最后，通过“date”属性将数组排列为字符串

//sort the object by a property (ascending)
//sorting takes into account uppercase and lowercase
sortBy(data, { prop: "date" });

如果你想忽略字母大小写，设置"parser"回调:

//sort the object by a property (descending)
//sorting ignores uppercase and lowercase
sortBy(data, {
    prop: "date",
    desc: true,
    parser: function (item) {
        //ignore case sensitive
        return item.toUpperCase();
    }
});

如果你想把"date"字段作为date类型:

//sort the object by a property (ascending)
//sorting parses each item to Date type
sortBy(data, {
    prop: "date",
    parser: function (item) {
        return new Date(item);
    }
});

在这里你可以玩上面的例子: jsbin.com/lesebi

Arr是一个对象数组，每个对象都有date_prop，它是一个日期。你可以像这样按降序/递减排序

 arr = arr.sort(function (a, b) {
      var dateA = new Date(a.date_prop).getTime();
      var dateB = new Date(b.date_prop).getTime();
      return dateA < dateB ? 1 : -1; // ? -1 : 1 for ascending/increasing order
    });

带日期的字符串在JavaScript中是可比较的(如果它们在语法上相同)，例如:

'2020-12-01' < '2020-12-02' == true

这意味着你可以在自定义排序函数中使用这个表达式:

var arr = [{id: 1、日期:“2020-12-01”},{id: 1、日期:“2020-12-15”},{id: 1、日期:' 2020-12-12 '}) 函数sortByDate(a, b) { 如果(a.date < b.date) { 返回1; ｝ If (a.date > b.date) { 返回1; ｝ 返回0; ｝ const sorted = arrr .sort(sortByDate); console.log(排序);
