组件源码

SlideContainer.js

import React, {useRef, useState} from "react";
 
export const SlideContainer = (props) => {
 
    const childrenArray = React.Children.toArray(props.children);
    const [left, setLeft] = useState(0);
    const [leftOriginal, setleftOriginal] = useState(0);
    const [run, setRun] = useState(false);
    const touchX = useRef(null);
 
    const mouseDown = (event) => {
        const x = event.clientX;
        touchX.current = x;
        setRun(true);
        setleftOriginal(left)
    }
 
    const mouseMove = (event) => {
        if (!run) {
            return;
        }
        const x = event.clientX;
        const move = x - touchX.current;
        if (leftOriginal + move <= -1 * 50 * (window.innerWidth / 100)) { // 移出边界
            return;
        }
        if (leftOriginal + move >= 0) { // 移出边界
            return;
        }
        setLeft(leftOriginal + move);
    }
 
    const mouseUp = (event) => {
        if (!run) {
            return;
        }
        if (left < -1 * 25 * (window.innerWidth / 100)) {
            setLeft(-1 * 50 * (window.innerWidth / 100));
        } else {
            setLeft(0)
        }
        setRun(false);
    }
 
    return (
        <div style={{width: '100vw', height: '100px', position: 'relative', overflow: 'hidden'}}
             onMouseDown={mouseDown} onMouseMove={mouseMove} onMouseUp={mouseUp}
        >
            <div style={{width: '150vw', position: 'absolute', display: 'flex', left: left + 'px'}}>
                <div style={{width: '100vw'}}>{childrenArray[0]}div>
                <div style={{width: '50vw'}}>{childrenArray[1]}div>
            div>
        div>
    )
}

使用样例

import {SlideContainer} from "./component/slide-view/slide-view";
 
const App = ()=> {
    return (
        <SlideContainer>
            <div>你好中国div>
            <div>
                <button type='button' style={{width:'25vw'}}>预览button>
                <button type='button' style={{width:'25vw'}}>删除button>
            div>
