Javascript新手在這裏:)我想實現......但不能弄明白。創建一個沒有任何重複數組的數組Javascript
這是我的數據。

這裏是我的代碼：
import { Injectable } from '@angular/core';
import { Http, Response } from '@angular/http';
@Injectable()
export class ShopifyService {
/**

constructor (
private http: Http
) {}
private shopifyUrl = 'app/heroes.json';
errorMessage: string;
/**

fetchProducts(): Promise<Response> {
return this.http.get(this.shopifyUrl)
.toPromise()
.then(this.extractData)
.catch(this.handleError);
}
private extractData(res: Response) {
if (res.status < 200 || res.status >= 300) {
throw new Error('Bad response status: ' + res.status);
}
let body = res.json();
if (body.data) {
return body.data;
}
else if (body.products) {
return body.products;
}
else {
return { };
}
}
private handleError (error: any) {
let errMsg = error.message || 'Server error';
console.error(errMsg);
return Promise.reject(errMsg);
}
private filterProducts(list, archetype) {
var result = [];

for (var i = 0; i < archetypes.length; i++) {
fetchedResponse = this.filterProducts(
products, archetypes[i]
);
result = result.concat(fetchedResponse);
}
return result;
},
error => this.errorMessage = <any>error
)
}
public findSingleProductVariant() {
var result = [],
j = 0;
return this.findVariants().then(
product => {
for (var i = 0; i < product.length; i++) {
// console.log(product[i]);
}
}
);
// return result;
}
findVariants() {
return this.findProducts(['Computer', 'Keyboard']).then(
products => {
var result = [];
for (var i = 0; i < products.length; i++) {
if (products[i].product_type === 'Computer') {
for (var j = 0; j < products.length; j++) {
if (products[j].product_type === 'Keyboard') {

}

直到我在這裏得到了什麼樣的一半。一組二維數組（其中一個來自鍵盤類型，另一個來自計算機類型）。
它是某事像這樣==>
[
[
[Computer_A],
[Keyboard_A]
],
[
[Computer_B],
[Keyboard_A]
],
[
[Computer_C],
[Keyboard_A]
],
]
現在這些對象中的每一個具有其自己的變體的陣列。我必須修改我的findSingleProductVariant以便遍歷這些陣列中的每一個，選擇一個keyboard變體（其陣列有一個價格字段），也可以選擇一個computer變體並計算價格。如果價格低於1000，它可以繼續選擇另一個鍵盤和計算機。但問題是它不能有兩個相同的數組。比如我們不能這樣做。
[
['Computer_A'], ['Keyboard_A'],
['Computer_A'], ['Keyboard_A'],
]
請問您能否以**文本形式**將相關數據添加到問題中？ –
一些字符串中的數字與桌子或燈具有什麼關係？ –
抱歉混淆妮娜:)在我的代碼中，我首先篩選某些產品類型，然後對它們進行篩選，我只對它們的價格感興趣。我會在問題中提供一部分真實數據。感謝您抽出時間 –
