使用 for 创建年龄数组

Question

我正在创建一个年龄选择器，我已经设置了所有轮播和屏幕，但是我在将数组设置为从 20 岁到 80 岁时遇到问题，我所做的测试是这样的

const dataAge = [
  {age: '21'},
  {age: '22'},
  {age: '23'},
  {age: '24'},
  {age: '25'},
  {age: '26'},
  {age: '27'},
  {age: '28'},
  {age: '29'},
  {age: '30'},
  {age: '31'},
  {age: '32'},
  {age: '33'},
  {age: '34'},
  {age: '35'},
  {age: '36'},
];

但我无法使用 FOR 来解决这个问题

这是要插入数组的代码

<View
          style={{
            backgroundColor: '#FFF',
            flex: 0.18,
            borderRadius: 10,
            margin: 10,
          }}>
          <View
            style={{
              flexDirection: 'row',
              flex: 1,
              justifyContent: 'space-between',
            }}>
            <Text style={{fontSize: 15, margin: 10, alignItems: 'flex-start'}}>
              Age
            </Text>
            <Text
              style={{
                fontSize: 10,
                alignItems: 'flex-end',
                margin: 10,
              }}>
              years old
            </Text>
          </View>
          {/* Age picker */}
          <View style={{alignItems: 'center'}}>
            <Carousel
              data={dataAge}
              renderItem={renderItemAge}
              sliderWidth={300}
              itemWidth={30}
              horizontal={true}
              firstItem={5}
              enableMomentum={true}
            />
          </View>
          <View style={styles.TriangleShapeView}></View>
        </View>

感谢帮助

Answer 1

试试这个：

let age = 20;
let dataAge = Array.from({ length: 61 }, () => {
  let obj = { age: age.toString() };
  age++;
  return obj;
});

console.log(dataAge);

Answer 2

只需遍历数组并将对象推送到它：

let dataAge = [];

for (let i = 20; i <= 80; i++) {
    dataAge.push({ age: i.toString() });
}

使用 for 创建年龄数组
