私のfilterProducts関数は存在するfindIntersectionを呼び出しますが、findIntersectionは定義されていません。Angularsjsがサービス機能を見つけることができません
angular.module('BrandService', [])
.service('BrandService', function ($filter, DataService) {
var productDb;
var products;
return {
filterProducts(brands, priceRange) {
var filteredProducts = [];
var brandProducts = [];
var priceProducts = [];
var productsArray = [];
var brandChecked = false;
var priceChecked = false;
angular.forEach(brands, function (brand) {
if (brand.checked) {
brandChecked = true;
angular.extend(brandProducts,
$filter('filter')(productDb, { 'brand': brand.name }));
}
if (brandChecked) {
productsArray.push(brandProducts);
console.log('brandProducts = ', brandProducts)
}
});
angular.forEach(priceRange, function (price) {
if (price.checked) {
priceChecked = true;
let filteredProductDb = productDb.filter((prod) => {
return (prod.price >= price.low && prod.price <= price.high);
});
angular.extend(priceProducts, filteredProductDb);
}
});
if (priceChecked) {
productsArray.push(priceProducts);
// console.log('priceProducts = ', priceProducts)
}
if (!brandChecked && !priceChecked) {
filteredProducts = products;
} else {
if (productsArray.length > 1) {
filteredProducts = findIntersection(productsArray);
} else {
filteredProducts = productsArray[0];
}
}
return filteredProducts;
},
findIntersection(productsArray) {
console.log('findIntersection called')
var filteredProducts = [];
var filteredSet = new Set();
for(var i=0; i < productsArray.length - 1; i++) {
var products1 = productsArray[i];
var products2 = productsArray[i+1];
angular.forEach(products1, function(product1) {
angular.forEach(products2, function(product2) {
if(product1._id == product2._id) {
filteredSet.add(product1);
}
});
});
}
filteredProducts = Array.from(filteredSet);
return filteredProducts;
}
}
})
私のfilterProducts関数は、存在するfindIntersectionを呼び出しますが、エラーを返します。findIntersectionは未定義です。
