javascript - 使用函数和参数迭代包含对象的数组

Question

我想创建一个函数来迭代包含具有名称、姓氏和年龄属性的单独对象的数组。该函数应采用参数“name”并在控制台中返回姓名和年龄。

我该怎么做？我看过其他一些问题，但似乎不知道该怎么做。到目前为止我已经创建了这个...

var people = [
  { name: "Sue", surname: "Beckett", age: 50},
  { name: "Bill", surname: "Borough", age: 44},
  { name: "Janet", surname: "Jupp", age: 23},
  { name: "Peter", surname: "Pepper", age: 21},
  { name: "Samantha", surname: "Salad", age: 17}
];


function person(name) {
  // code here
}

person(sue)

Answer 1

只需使用 Array#find() method像这样:

function person(name) {
  return people.find(function(p) {
    return p.name == name;
  });
}
console.log(person("Samantha"));

演示:

var people = [{
    name: "Sue",
    surname: "Beckett",
    age: 50
  },
  {
    name: "Bill",
    surname: "Borough",
    age: 44
  },
  {
    name: "Janet",
    surname: "Jupp",
    age: 23
  },
  {
    name: "Peter",
    surname: "Pepper",
    age: 21
  },
  {
    name: "Samantha",
    surname: "Salad",
    age: 17
  }
];

function person(name) {
  return people.find(function(p) {
    return p.name == name;
  });
}
console.log(person("Samantha"));
console.log(Object.values(person("Samantha")));

注意:

• 确保在调用方法时将名称作为字符串传递，仅传递sue而不传递""将假设您有一个名为 sue 的变量。
• 请注意，您可以使用 Object.values() 仅显示以下值对象属性，而不是整个对象。

简单地写:

console.log(Object.values(person("Samantha")));
