我正在尝试重新创建位置列表上显示的 Google“营业时间”下拉列表。
营业时间数组如下所示:
[
{id: 5d991d1208ac396803a992ee, day: 'sunday', open: 560, close: 1050},
{id: 5d991d1208ac396803a992ef, day: 'monday', open: 560, close: 1050},
{id: 5d991d1208ac396803a992eg, day: 'tuesday', open: 560, close: 1050},
{id: 45d991d1208ac396803a992e, day: 'wednesday', open: 560, close: 1050},
{id: 5d991d1208ac396803a992eh, day: 'thursday', open: 560, close: 1050},
{id: 5d991d1208ac396803a992eI, day: 'friday', open: 560, close: 1050},
{id: 5d991d1208ac396803a992eG, day: 'saturday', open: 560, close: 1050},
]
所以，如果当天是星期二，我想返回一个像这样的排序数组:
[
{id: 5d991d1208ac396803a992eg, day: 'tuesday', open: 560, close: 1050},
{id: 45d991d1208ac396803a992e, day: 'wednesday', open: 560, close: 1050},
....
]
我正在使用 mongoose 和 MongoDB。
更新 ID 是由 MongoDB 生成的，因此我无法对它们进行排序或匹配。
最佳答案
使用扩展运算符进行切片和连接:
// needs the day of the week
// starting from Sunday as 0 and saturday as 6 since getDay()
// starts from 0
const currentDay = new Date().getDay() // 0, 1, 2, 3, 4, 5, or 6
// here's your function
const getSortedArray = (arr) => [
...arr.slice(currentDay),
...arr.slice(0, currentDay)
]
// example
const days = [{
id: '5d991d1208ac396803a992ee',
day: 'sunday',
open: 560,
close: 1050
},
{
id: '5d991d1208ac396803a992ef',
day: 'monday',
open: 560,
close: 1050
},
{
id: '5d991d1208ac396803a992eg',
day: 'tuesday',
open: 560,
close: 1050
},
{
id: '45d991d1208ac396803a992e',
day: 'wednesday',
open: 560,
close: 1050
},
{
id: '5d991d1208ac396803a992eh',
day: 'thursday',
open: 560,
close: 1050
},
{
id: '5d991d1208ac396803a992eI',
day: 'friday',
open: 560,
close: 1050
},
{
id: '5d991d1208ac396803a992eG',
day: 'saturday',
open: 560,
close: 1050
},
]
// ensure order of days
const daysSorted = ['sunday', 'monday', 'tuesday', 'wednesday', 'thursday', 'friday', 'saturday']
.map(day => days.filter(el => el.day === day)[0])
console.log(getSortedArray(daysSorted))关于node.js - MongoDB - 营业时间，按当天排序，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/59044505/
