如何基于任意对象值对数组进行排序？

问题描述：

[{ 
    "dayOfWeek": "TUESDAY", 
    "startTime": "19:30:00", 
    "endTime": "21:15:00" 
}, { 
    "dayOfWeek": "SATURDAY", 
    "startTime": "19:15:00", 
    "endTime": "21:00:00" 
}, { 
    "dayOfWeek": "FRIDAY", 
    "startTime": "19:00:00", 
    "endTime": "20:15:00" 
}, { 
    "dayOfWeek": "THURSDAY", 
    "startTime": "19:15:00", 
    "endTime": "20:30:00" 
}, { 
    "dayOfWeek": "WEDNESDAY", 
    "startTime": "19:30:00", 
    "endTime": "20:45:00" 
}, { 
    "dayOfWeek": "SUNDAY", 
    "startTime": "19:30:00", 
    "endTime": "20:45:00" 
}, { 
    "dayOfWeek": "MONDAY", 
    "startTime": "19:30:00", 
    "endTime": "21:00:00" 
}]

然而，这种数据来自具有不规则分选的API，其不能被信任。我需要将这个数组从MONDAY到SUNDAY的值递减。我怎样才能做到这一点？我假设我必须设置某种地图进行查找？

右键，创建一个对象，它的键是当日的名称和它的值是0〜6（或1至7或任何你想要的），然后使用你的'的.sort（）'比较器功能。 – Pointy

答

您可以使用一个对象，使用日期和值进行排序。

var array = [{ dayOfWeek: "TUESDAY", startTime: "19:30:00", endTime: "21:15:00" }, { dayOfWeek: "SATURDAY", startTime: "19:15:00", endTime: "21:00:00" }, { dayOfWeek: "FRIDAY", startTime: "19:00:00", endTime: "20:15:00" }, { dayOfWeek: "THURSDAY", startTime: "19:15:00", endTime: "20:30:00" }, { dayOfWeek: "WEDNESDAY", startTime: "19:30:00", endTime: "20:45:00" }, { dayOfWeek: "SUNDAY", startTime: "19:30:00", endTime: "20:45:00" }, { dayOfWeek: "MONDAY", startTime: "19:30:00", endTime: "21:00:00" }]; 
 

 
array.sort(function (a, b) { 
 
    var sort = { MONDAY: 1, TUESDAY: 2, WEDNESDAY: 3, THURSDAY: 4, FRIDAY: 5, SATURDAY: 6, SUNDAY: 7 }; 
 
    return sort[a.dayOfWeek] - sort[b.dayOfWeek]; 
 
}); 
 

 
console.log(array);

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