在Typescript中,遍历元组数组并获取特定值可以通过以下方式实现:
const tupleArray: [string, number][] = [["apple", 1], ["banana", 2], ["orange", 3]];
for (const tuple of tupleArray) {
if (tuple[0] === "banana") {
console.log(tuple[1]); // 输出:2
break;
}
}
const tupleArray: [string, number][] = [["apple", 1], ["banana", 2], ["orange", 3]];
const result = tupleArray.find(tuple => tuple[0] === "banana");
if (result) {
console.log(result[1]); // 输出:2
}
const tupleArray: [string, number][] = [["apple", 1], ["banana", 2], ["orange", 3]];
const filteredArray = tupleArray.filter(tuple => tuple[0] === "banana");
if (filteredArray.length > 0) {
console.log(filteredArray[0][1]); // 输出:2
}
以上是三种常见的遍历元组数组并获取特定值的方法。根据具体的需求和场景选择合适的方法即可。
