根据某些字段的值匹配2个数组
我在名为myBar的数组中有以下成分列表。该成分包含在属性“名称”中
myBar: Array [
bar {
"category": "spirits",
"id": "1",
"ingredientId": "2003",
"name": "vodka",
},
bar {
"category": "juice",
"id": "2",
"ingredientId": "2017",
"name": "orange juice",
},
bar {
"category": "juice",
"id": "3",
"ingredientId": "2020",
"name": "lemon juice",
},
bar {
"category": "juice",
"id": "4",
"ingredientId": "2027",
"name": "Pineapple Juice",
},
bar {
"category": "juice",
"id": "5",
"ingredientId": "2018",
"name": "apple Juice",
},
bar {
"category": "juice",
"id": "6",
"ingredientId": "2025",
"name": "Lime Juice",
},
bar {
"category": "spirits",
"id": "7",
"ingredientId": "2001",
"name": "gin",
},
bar {
"category": "spirits",
"id": "8",
"ingredientId": "2005",
"name": "whiskey",
},
bar {
"category": "spirits",
"id": "9",
"ingredientId": "2002",
"name": "rum",
},
]
我还有一个名为cocktailList 的第二个数组，其中包含鸡尾酒配方列表。在这里，成分包含在“成分”字段中。
cocktailList: Array [
Object {
"alcoholic": "true",
"drinkId": "1101",
"ingredients": " gin, lime syrup, lime",
},
Object {
"alcoholic": "true",
"drinkId": "1102",
"ingredients": "vodka, orange juice",
},
Object {
"alcoholic": "true",
"drinkId": "1103",
"ingredients": "rum, coke",
},
Object {
"alcoholic": "true",
"drinkId": "1104",
"ingredients": "sweet vermouth, campari, prosecco",
},
Object {
"alcoholic": "true",
"drinkId": "1105",
"ingredients": "Gin, Olive Juice, Olives, Dry vermouth",
},
Object {
"alcoholic": "true",
"drinkId": "1106",
"ingredients": " Vodka, Triple Sec, Lime Juice",
},
Object {
"alcoholic": "true",
"drinkId": "1107",
"ingredients": " vodka, Raspberry Liqueur, Pineapple Juice",
}
]
我正在尝试根据配料的含量来检查我可以制作哪些鸡尾酒。这个想法是迭代每个食谱（在cocktailList中）并检查所有成分是否也是我在myBar中的成分列表的一部分。
例如，“drinkId”：“1102”应该返回 true，因为我的myBar中有所有成分（伏特加和橙汁） ，而“drinkId”：“1101”应该返回 false，因为我既没有酸橙糖浆也没有酸橙。

从第一个数组创建一个成分名称数组，以便您可以快速搜索直接数组中的成分。// arr1 is your list of ingredients in your bar.var arrName = [];arr1.forEach(element => arrName.push(element.name));console.log(arrName);Output:["vodka", "orange juice", "lemon juice", "Pineapple Juice", "apple Juice", "Lime Juice", "gin", "whiskey", "rum"]现在遍历cocktailList并在 中搜索每种成分arrName。如果匹配元素的数量等于鸡尾酒中成分的数量，那么它就是一个匹配项。var finalArr = arr2.filter(function(obj){ var arrIngredient = obj.ingredients.split(','); var intMatch = 0; arrIngredient.forEach(element => arrName.indexOf(element.trim()) >= 0 ? intMatch++ : ''); return arrIngredient.length == intMatch;});console.log(finalArr);Output:[ { alcoholic: "true" drinkId: "1102" ingredients: "vodka, orange juice" }]
