我是web新手，我想在同一个页面上多次使用此javascript代码，用于多个旋转木马，但它只适用于第一个旋转木马，我尝试更改名称，但没有帮助！

这是js代码:

    const slider = document.querySelector('.items');
    let isDown = false;
    let startX;
    let scrollLeft;

    slider.addEventListener('mousedown', (e) => {
        isDown = true;
        slider.classList.add('active');
        startX = e.pageX - slider.offsetLeft;
        scrollLeft = slider.scrollLeft;
    });
    slider.addEventListener('mouseleave', () => {
        isDown = false;
        slider.classList.remove('active');
    });
    slider.addEventListener('mouseup', () => {
        isDown = false;
        slider.classList.remove('active');
    });
    slider.addEventListener('mousemove', (e) => {
        if (!isDown) return;
        e.preventDefault();
        const x = e.pageX - slider.offsetLeft;
        const walk = (x - startX) * 1; //scroll-fast
        slider.scrollLeft = scrollLeft - walk;
        console.log(walk);
    });

这是html，为了让您了解名称，我把它做得很短，并删除了所有项，以便您可以更快地阅读它。如果您想运行它，您应该添加8个或更多项:

    const slider = document.querySelector('.items');
    let isDown = false;
    let startX;
    let scrollLeft;

    slider.addEventListener('mousedown', (e) => {
        isDown = true;
        slider.classList.add('active');
        startX = e.pageX - slider.offsetLeft;
        scrollLeft = slider.scrollLeft;
    });
    slider.addEventListener('mouseleave', () => {
        isDown = false;
        slider.classList.remove('active');
    });
    slider.addEventListener('mouseup', () => {
        isDown = false;
        slider.classList.remove('active');
    });
    slider.addEventListener('mousemove', (e) => {
        if (!isDown) return;
        e.preventDefault();
        const x = e.pageX - slider.offsetLeft;
        const walk = (x - startX) * 1; //scroll-fast
        slider.scrollLeft = scrollLeft - walk;
        console.log(walk);
    });

和css:

    const slider = document.querySelector('.items');
    let isDown = false;
    let startX;
    let scrollLeft;

    slider.addEventListener('mousedown', (e) => {
        isDown = true;
        slider.classList.add('active');
        startX = e.pageX - slider.offsetLeft;
        scrollLeft = slider.scrollLeft;
    });
    slider.addEventListener('mouseleave', () => {
        isDown = false;
        slider.classList.remove('active');
    });
    slider.addEventListener('mouseup', () => {
        isDown = false;
        slider.classList.remove('active');
    });
    slider.addEventListener('mousemove', (e) => {
        if (!isDown) return;
        e.preventDefault();
        const x = e.pageX - slider.offsetLeft;
        const walk = (x - startX) * 1; //scroll-fast
        slider.scrollLeft = scrollLeft - walk;
        console.log(walk);
    });

顺晟科技：

在旋转木马中创建几个项目:

    const slider = document.querySelector('.items');
    let isDown = false;
    let startX;
    let scrollLeft;

    slider.addEventListener('mousedown', (e) => {
        isDown = true;
        slider.classList.add('active');
        startX = e.pageX - slider.offsetLeft;
        scrollLeft = slider.scrollLeft;
    });
    slider.addEventListener('mouseleave', () => {
        isDown = false;
        slider.classList.remove('active');
    });
    slider.addEventListener('mouseup', () => {
        isDown = false;
        slider.classList.remove('active');
    });
    slider.addEventListener('mousemove', (e) => {
        if (!isDown) return;
        e.preventDefault();
        const x = e.pageX - slider.offsetLeft;
        const walk = (x - startX) * 1; //scroll-fast
        slider.scrollLeft = scrollLeft - walk;
        console.log(walk);
    });

之后，这在很大程度上取决于您想要的位置
