检查滚动视图是否正在滚动

const scrollView = document.getElementById('scrollView');

let isScrolling = false;

scrollView.addEventListener('scroll', () => {
  isScrolling = true;
  clearTimeout(scrollTimeout);

  scrollTimeout = setTimeout(() => {
    isScrolling = false;
  }, 66); // 大约每秒15帧
});

// 检查滚动状态
function checkScrollingStatus() {
  console.log('Is scrolling:', isScrolling);
  return isScrolling;
}

import React, { useState } from 'react';
import { ScrollView, Text } from 'react-native';

const App = () => {
  const [isScrolling, setIsScrolling] = useState(false);

  return (
    <ScrollView
      onScroll={() => setIsScrolling(true)}
      onMomentumScrollEnd={() => setIsScrolling(false)}
    >
      <Text>Scroll me!</Text>
      {/* 其他内容 */}
    </ScrollView>
  );
};

export default App;

function throttle(func, limit) {
  let inThrottle;
  return function() {
    const args = arguments;
    const context = this;
    if (!inThrottle) {
      func.apply(context, args);
      inThrottle = true;
      setTimeout(() => inThrottle = false, limit);
    }
  };
}

scrollView.addEventListener('scroll', throttle(() => {
  console.log('Scrolling...');
}, 100));
