我有一个需要排序的对象数组。有两个选择框，一个按Date（asc / desc）属性排序，另一个按＆＃34; surveyStatus＆＃34;排序。属性。

日期的可能值为null或日期时间戳。

SurveyStatus有3个可能的值，0,1,2。

“调查状态”的默认排序顺序为1,2,0

2 个答案:

答案 0 :(得分：1)

通常，按照以下标准进行排序：

theArray.sort(function(left, right) {
    var result = /*...compare first criterion*/;
    if (result == 0) {
        result = /*...compare second criterion*/;
        if (result == 0) {
            result = /*...compare third criterion*/;
            // ...and so on...
        }
    }
    return result;
});

...如果left应该在right之前，那么“比较X标准”会产生一个负数，如果它们对于该标准是相同的则为0，如果{right则为正数1}}应该在left之前。

这是有效的，因为我们只需要评估我们的第二个标准，如果条目是根据第一个“相同”，只需要查看第三个，如果第一个和第二个是“相同的，“等等。

这是一个硬编码系列。它可以很容易地适用于由比较数组定义的系列（使用在result不为0时中断的循环）。

硬编码版本的简单示例：

var array = [
  {a: 4, b: 3, c: 5},
  {a: 1, b: 2, c: 7},
  {a: 4, b: 4, c: 4},
  {a: 4, b: 4, c: 2},
  {a: 4, b: 4, c: 6},
  {a: 2, b: 8, c: 9},
  {a: 2, b: 9, c: 8}
];
show("Unsorted", array);
array.sort(function(left, right) {
  var result = left.a - right.a;
  if (result == 0) {
    result = left.b - right.b;
    if (result == 0) {
      result = left.c - right.c;
    }
  }
  return result;
});
show("Sorted", array);

function show(label, a) {
  console.log(
    label,
    a.map(function(entry) {
      return "a:" + entry.a +
             ",b:" + entry.b +
             ",c:" + entry.c;
    })
  );
}
.as-console-wrapper {
  max-height: 100% !important;
}

您可以在单独的对象中定义比较函数，并在调用sort时引用您需要的函数：

以下是一个代码片段：

请注意，sort在大多数浏览器中提供稳定的排序，这意味着如果您首先按日期排序，然后按状态排序，则记录仍将按日期在同一状态组中排序。
