封装一个自定义hooks

import { useRef, useState, useEffect } from 'react';

export useFixRollingPenetration = (domId) => {
  let targetLeftY = 0;
  const isMiniAppType = isMiniApp || isRealWeChatMiniProgram;

  const disableTouchMove = useRef((e) => {
    const scrollBox = document.getElementById(domId)
    if (scrollBox) {
      //target是否在scrollBox之内,不在范围内就别滚动
      if (!scrollBox.contains(e.target)) {
        e.preventDefault();
      }
    }
  });
  const preventScrolling = () => {
    if (!isMiniAppType && document && document.body) {
      document.body.addEventListener('touchmove', disableTouchMove.current, {
        passive: false,
      });
    }
  };
  const allowScrolling = () => {
    if (!isMiniAppType && document && document.body) {
      document.body.removeEventListener('touchmove', disableTouchMove.current, {
        /** @ts-ignore */
        passive: false,
      });
    }
  };

  function onTouchStart(e) {
    targetLeftY = Math.floor(e.targetTouches[0].clientY);
  }
  function onTouchMove(e) {
    let newTargetY = Math.floor(e.targetTouches[0].clientY);
    let dom = document.getElementById(domId);
    let sT = dom.scrollTop;
    let sH = dom.scrollHeight;
    let cH = dom.clientHeight;
    // 判断是否滚动溢出，溢出后e.preventDefault();
    if (sT <= 0 && newTargetY - targetLeftY > 0 && targetLeftY !== 0) {
      e.preventDefault();
    } else if ((sT >= sH - cH) && (newTargetY - targetLeftY < 0)) {
      e.preventDefault();
    }
  }

  return {
    preventScrolling,
    allowScrolling,
    onTouchStart,
    onTouchMove,
  }
}

输入未传入的dom id字符串，输出为四个方法

使用：

  const {
    preventScrolling,
    allowScrolling,
    onTouchStart,
    onTouchMove,
    onTouchEnd
  } = useFixRollingPenetration('brand-scroll');

  useEffect(() => {
    if (showPad) {
      preventScrolling();
    } else {
      allowScrolling();
    }
    return () => {
      allowScrolling();
    }
  }, [showPad])

<div className="brand-scroll-wrapper" id='brand-scroll'
    onTouchStart={onTouchStart}
    onTouchMove={onTouchMove}
 />
