只有CSS

html {
    scroll-behavior: smooth;
}

你只需要加上这个。现在你的内部链接滚动行为将是流畅的像一个流。

程序化:一些额外的和高级的东西

// Scroll to specific values
// window.scrollTo or window.scroll
window.scroll({
  top: 1000, 
  left: 0, 
  behavior: 'smooth'
});

// Scroll certain amounts from current position 
window.scrollBy({ 
  top: 250, // could be negative value
  left: 0, 
  behavior: 'smooth' 
});

// Scroll to a certain element
document.getElementById('el').scrollIntoView({
  behavior: 'smooth'
})

注意:所有最新的浏览器(Opera, Chrome, Firefox等)都支持此功能。

要详细了解，请阅读这篇文章

$("a").on("click", function(event){
    //check the value of this.hash
    if(this.hash !== ""){
        event.preventDefault();

        $("html, body").animate({scrollTop:$(this.hash).offset().top}, 500);

        //add hash to the current scroll position
        window.location.hash = this.hash;

    }



});

对于正在寻找ReactJS (TypeScript)方法的用户。

function Hero() {
  const scrollToView = (e: any) => {
    e.preventDefault();
    // Scroll to a certain element
    document.getElementById("about-section")?.scrollIntoView({
      behavior: "smooth",
    });
  };
  return (
    <section id="hero">
        <button
          onClick={scrollToView} 
        >
          Learn More
        </button>    
    </section>
  );
}

export default Hero;

以及about-section组件

const AboutSection = () => {
  return (
    <section id="about-section"  >
      <h1>About Section</h1>
    </section>
  );
};

export default AboutSection;

现在的浏览器要快一些。setInterval可能有用。现在这个功能在Chrome和Firefox中运行良好。(safari有点慢，不用IE)

function smoothScroll(event) {
    if (event.target.hash !== '') { //Check if tag is an anchor
        event.preventDefault()
        const hash = event.target.hash.replace("#", "")
        const link = document.getElementsByName(hash) 
        //Find the where you want to scroll
        const position = link[0].getBoundingClientRect().y 
        let top = 0

        let smooth = setInterval(() => {
            let leftover = position - top
            if (top === position) {
                clearInterval(smooth)
            }

            else if(position > top && leftover < 10) {
                top += leftover
                window.scrollTo(0, top)
            }

            else if(position > (top - 10)) {
                top += 10
                window.scrollTo(0, top)
            }

        }, 6)//6 milliseconds is the faster chrome runs setInterval
    }
}

本机支持在哈希id滚动上平滑滚动。

html {
  scroll-behavior: smooth;
}

大家可以看看:https://www.w3schools.com/howto/howto_css_smooth_scroll.asp#section2

有一种css方法可以使用scroll-behavior来做到这一点。添加以下属性。

    scroll-behavior: smooth;

就是这样。不需要JS。

a { display: inline-block; width: 50px; text-decoration: none; } nav, scroll-container { display: block; margin: 0 auto; text-align: center; } nav { width: 339px; padding: 5px; border: 1px solid black; } scroll-container { display: block; width: 350px; height: 200px; overflow-y: scroll; scroll-behavior: smooth; } scroll-page { display: flex; align-items: center; justify-content: center; height: 100%; font-size: 5em; } <nav> <a href="#page-1">1</a> <a href="#page-2">2</a> <a href="#page-3">3</a> </nav> <scroll-container> <scroll-page id="page-1">1</scroll-page> <scroll-page id="page-2">2</scroll-page> <scroll-page id="page-3">3</scroll-page> </scroll-container>

PS:请检查浏览器兼容性。
