【问题描述】：
我正在尝试通过某些条件实现嵌套排序。例如，我有一个对象数组：
我拥有的对象数组：
var objArray = [
{
total: 2,
completed: 1,
created: "2021-03-19T13:09:57.9191082",
},
{
total: 2,
completed: 0,
created: "2021-03-19T15:36:32.5761928",
},
{
total: 2,
completed: 1,
created: "2021-03-19T15:40:47.1690151",
},
{
total: 3,
completed: 1,
created: "2021-03-22T09:33:03.1541255",
},
{
total: 2,
completed: 1,
created: "2021-03-23T08:42:45.9854381",
},
{
total: 2,
completed: 1,
created: "2021-03-23T09:37:17.8576954",
},
{
total: 22,
completed: 2,
created: "2021-03-23T09:40:16.1180247",
},
{
total: 22,
completed: 21,
created: "2021-03-23T10:07:13.6602386",
},
{
total: 2,
completed: 2,
created: "2021-04-01T08:41:17.2340404",
},
{
total: 2,
completed: 1,
created: "2021-04-01T09:33:20.9257699",
},
{
total: 2,
completed: 2,
created: "2021-04-01T09:40:13.4354591",
},
{
total: 2,
completed: 1,
created: "2021-04-07T07:43:03.8319172",
},
{
total: 4,
completed: 0,
created: "2021-04-07T07:50:36.8278655",
},
{
total: 2,
completed: 2,
created: "2021-04-07T08:31:05.2998603",
},
{
total: 2,
completed: 1,
created: "2021-04-07T08:31:53.3266938",
},
{
total: 3,
completed: 0,
created: "2021-04-15T08:18:33.1249212",
},
{
total: 3,
completed: 1,
created: "2021-04-15T08:21:25.5196674",
},
];
我想要实现的对象数组：
var objArray = [
{
percentage: '0',
total: 2,
completed: 0,
created: '2021-03-19T15:36:32.5761928',
},
{
percentage: '0',
total: 4,
completed: 0,
created: '2021-04-07T07:50:36.8278655',
},
{
percentage: '0',
total: 3,
completed: 0,
created: '2021-04-15T08:18:33.1249212',
},
{
percentage: '95',
total: 22,
completed: 21,
created: '2021-03-23T10:07:13.6602386',
},
{
percentage: '50',
total: 2,
completed: 1,
created: '2021-03-19T13:09:57.9191082',
},
{
percentage: '50',
total: 2,
completed: 1,
created: '2021-03-19T15:40:47.1690151',
},
{
percentage: '50',
total: 2,
completed: 1,
created: '2021-03-23T08:42:45.9854381',
},
{
percentage: '50',
total: 2,
completed: 1,
created: '2021-03-23T09:37:17.8576954',
},
{
percentage: '50',
total: 2,
completed: 1,
created: '2021-04-01T09:33:20.9257699',
},
{
percentage: '50',
total: 2,
completed: 1,
created: '2021-04-07T07:43:03.8319172',
},
{
percentage: '50',
total: 2,
completed: 1,
created: '2021-04-07T08:31:53.3266938',
},
{
percentage: '33',
total: 3,
completed: 1,
created: '2021-03-22T09:33:03.1541255',
},
{
percentage: '33',
total: 3,
completed: 1,
created: '2021-04-15T08:21:25.5196674',
},
{
percentage: '9',
total: 22,
completed: 2,
created: '2021-03-23T09:40:16.1180247',
},
{
percentage: '100',
total: 2,
completed: 2,
created: '2021-04-07T08:31:05.2998603',
},
{
percentage: '100',
total: 2,
completed: 2,
created: '2021-04-01T09:40:13.4354591',
},
{
percentage: '100',
total: 2,
completed: 2,
created: '2021-04-01T08:41:17.2340404',
},
];
从这个对象数组中，我映射对象并创建额外的键/值“百分比”来计算总数和完成之间的百分比，并按完成的百分比对它们进行排序。完成百分比排序后，我还有其他条件。如果百分比为 100% 完成，则按“创建”日期字段对 100% 完成的任务进行排序。如果百分比在 1 - 99 之间，则按完成百分比排序，例如，如果两个字段之间的完成百分比相同，则按日期排序。此外，如果完成的百分比为 0，则按 asc date 排序。
我已经尝试过这个功能，但无法对 1 到 99 之间的百分比进行排序。对此有什么帮助吗？
