javascript - 有条件地将字符串和数字数组组合为对象数组

Question

我有两个数组，一个是字符串类型，第二个是数字类型。如何有条件地将这些组合为键值对象。

例如:

var fruits = [
  "Apple",
  "Banana" ,
  "Apricot",
  "Bilberry"
]

var count = [3,5,0,2]

我想将 fruits 和 count 数组组合为键值对象，并且哪个计数不是 0

预期:

var merge = [{"Apple":3},{"Banana" :5},{"Bilberry":2}]

我尝试过的是:

var merge = _.zipObject(["Apple","Banana" ,"Apricot","Bilberry"], [3,5,0,2])

结果是:

{"Apple":3,"Banana":5 ,"Apricot":0,"Bilberry":2}

Answer 1

尝试使用 filter、Object.values 和 map 来尝试这个普通的 js 解决方案

var output = count.map((s, i) => ({
  [fruits[i]]: s
})).filter(s => Object.values(s)[0]);

演示

var fruits = [
  "Apple",
  "Banana",
  "Apricot",
  "Bilberry"
];

var count = [3, 5, 0, 2];

var output = count.map((s, i) => ({
  [fruits[i]]: s
})).filter(s => Object.values(s)[0]);

console.log(output);
