在Javascript中捕获Promise.all()的解决方案

// 创建Promise对象数组
const promise1 = new Promise((resolve, reject) => {
  setTimeout(() => {
    resolve('Promise 1 resolved');
  }, 2000);
});

const promise2 = new Promise((resolve, reject) => {
  setTimeout(() => {
    resolve('Promise 2 resolved');
  }, 3000);
});

const promise3 = new Promise((resolve, reject) => {
  setTimeout(() => {
    resolve('Promise 3 resolved');
  }, 1000);
});

// 使用Promise.all()处理Promise对象数组
Promise.all([promise1, promise2, promise3])
  .then((results) => {
    // 在所有Promise对象都解决后执行的操作
    console.log(results); // 输出包含所有Promise对象解决值的数组
  })
  .catch((error) => {
    // 处理错误
    console.error(error);
  });
