let initialHeight = window.innerHeight;

window.addEventListener('resize', () => {
  let currentHeight = window.innerHeight;
  if (currentHeight > initialHeight) {
    // 键盘收起
    console.log('键盘已收起');
    initialHeight = currentHeight; // 更新初始高度
  } else {
    // 键盘弹出或尺寸未变化
    initialHeight = currentHeight;
  }
});

const inputElement = document.querySelector('input');

inputElement.addEventListener('blur', () => {
  console.log('键盘已收起');
});

let initialHeight = window.innerHeight;
let timer = setInterval(() => {
  let currentHeight = window.innerHeight;
  if (currentHeight > initialHeight) {
    console.log('键盘已收起');
    clearInterval(timer);
    initialHeight = currentHeight;
  }
}, 100); // 每100毫秒检查一次
