Javascript 根据总价格对航班优惠数组进行排序并检索前五个结果 Angular HTTP请求

我发送API请求并获取:

Object { meta: {…}, data: (75) […], dictionaries: {…} }
​
data: Array(75) [ {…}, {…}, {…}, … ]
​​
0: Object { type: "flight-offer", id: "1", source: "GDS", … }
​​
1: Object { type: "flight-offer", id: "2", source: "GDS", … }
​​
2: Object { type: "flight-offer", id: "3", source: "GDS", … }
​​
3: Object { type: "flight-offer", id: "4", source: "GDS", … }
​​
4: Object { type: "flight-offer", id: "5", source: "GDS", … }
​​
5: Object { type: "flight-offer", id: "6", source: "GDS", … }
​​
6: Object { type: "flight-offer", id: "7", source: "GDS", … }
​​
7: Object { type: "flight-offer", id: "8", source: "GDS", … }
​​
8: Object { type: "flight-offer", id: "9", source: "GDS", … }
​​
9: Object { type: "flight-offer", id: "10", source: "GDS", … }
​​
10: Object { type: "flight-offer", id: "11", source: "GDS", … }
​​
11: Object { type: "flight-offer", id: "12", source: "GDS", … }
​​
12: Object { type: "flight-offer", id: "13", source: "GDS", … }
​​
13: Object { type: "flight-offer", id: "14", source: "GDS", … }

每个物体看起来都像:

0: Object { type: "flight-offer", id: "1", source: "GDS", … }
​​​
id: "1"
​​​
instantTicketingRequired: false
​​​
itineraries: Array [ {…} ]
​​​
lastTicketingDate: "2024-04-20"
​​​
lastTicketingDateTime: "2024-04-20"
​​​
nonHomogeneous: false
​​​
numberOfBookableSeats: 9
​​​
oneWay: false
​​​
price: Object { currency: "EUR", total: "580.13", base: "257.00", … }
​​​
pricingOptions: Object { fareType: (1) […], includedCheckedBagsOnly: true }
​​​
source: "GDS"
​​​
travelerPricings: Array [ {…} ]
​​​
type: "flight-offer"
​​​
validatingAirlineCodes: Array [ "TK" ]

我想根据价格对结果进行排序.因此，我根据价格拥有所有这些对象的数组，然后我想获得前5个结果.

我try 过:

this.http.get(url, { headers: this.headers }).subscribe((data: any) => {
      this.responseData$ = data;
      console.log(data);
      const flightOffers = data.data || []; // Assuming flight offers are in `data.data`

      // Sort the flight offers by price.total
      let sortedResults: any[] = flightOffers.sort(
        (offerA: any, offerB: any) => {
          // Ensure both offers have a price object 和 total property
          if (
            !offerA.price ||
            !offerA.price.total ||
            !offerB.price ||
            !offerB.price.total
          ) {
            console.warn(
              'One or more offers lack a valid price object or total property.',
            );
            return 0; // Maintain original order in case of missing prices
          }

          return offerA.price.total - offerB.price.total;
        },
      );

和

this.http.get(url, { headers: this.headers }).subscribe((data: any) => {
      this.responseData$ = data;
      console.log(data);
      let sortedResults = [];
      if (Array.isArray(data.data)) {
        sortedResults = data.data.sort((a, b) => {
          return parseFloat(a.price.total) - parseFloat(b.price.total);
        });
      }
      const firstFiveResults = sortedResults.slice(0, 5);

but it didnt work, 和 i get the array with 5 elements with the same price: total. How to sort it?
