在 JavaScript 中按日期升序和降序对包含对象的嵌套数组进行排序
javascriptweb developmentfront end technologyobject oriented programming
假设我们有一个 JSON 对象，其中包含类似这样的嵌套数组 −
const arr = {
"DATA": [
{
"BookingID": "9513",
"DutyStart": "2016-02-11 12:00:00"
},
{
&"BookingID":"91157307"，
&"DutyStart":"2016-02-11 13:00:00"
}，
{
&"BookingID":"95117317"，
"DutyStart":"2016-02-11 13:30:00"
},
{
"BookingID":"957266"，
"DutyStart":"2016-02-12 19:15:00"
},
{
&"BookingID": &"74",
&"DutyStart": &"2016-02-11 12:21:00"
}
]
};
我们需要编写一个 JavaScript 函数，该函数接受一个这样的对象，并根据 'dutyStart' 属性按升序或降序对嵌套数组进行排序。
示例
其代码为 −
const arr = {
"DATA": [
{
"BookingID": "9513",
"DutyStart": "2016-02-11 12:00:00"
},
{
"BookingID": "91157307",
"DutyStart": "2016-02-11 13:00:00"
},
{
"BookingID": "95117317",
"DutyStart": "2016-02-11 13:30:00"
},
{
"BookingID": "957266",
"DutyStart": "2016-02-12 19:15:00"
},
{
"BookingID": "74",
"DutyStart": "2016-02-11 12:21:00"
}
]
};
const sortByDate = arr => {
const sorter = (a, b) => {
return new Date(a.DutyStart).getTime() - new Date(b.DutyStart).getTime();
};
arr["DATA"].sort(sorter);
return arr;
};
console.log(sortByDate(arr));
输出
控制台中的输出将是 −
{
DATA: [
{ BookingID: '9513', DutyStart: '2016-02-11 12:00:00' },
{ BookingID: '74', DutyStart: '2016-02-11 12:21:00' },
{ BookingID: '91157307', DutyStart: '2016-02-11 13:00:00' },
{ BookingID: '95117317', DutyStart: '2016-02-11 13:30:00' },
{ BookingID: '957266', DutyStart: '2016-02-12 19:15:00' }
]
}
