给出的答案可以工作，但会禁用外向链接。下面的版本与额外的奖金放松(摇摆)和尊重外向的链接。

$(document).ready(function () {
    $('a[href^="#"]').on('click', function (e) {
        e.preventDefault();

        var target = this.hash;
        var $target = $(target);

        $('html, body').stop().animate({
            'scrollTop': $target.offset().top
        }, 900, 'swing', function () {
            window.location.hash = target;
        });
    });
});

正确的语法是:

//Smooth scrolling with links
$('a[href^=\\#]').on('click', function(event){     
    event.preventDefault();
    $('html,body').animate({scrollTop:$(this.hash).offset().top}, 500);
});

// Smooth scrolling when the document is loaded and ready
$(document).ready(function(){
  $('html,body').animate({scrollTop:$(location.hash).offset().‌​top}, 500);
});

简化:干

function smoothScrollingTo(target){
  $('html,body').animate({scrollTop:$(target).offset().​top}, 500);
}
$('a[href^=\\#]').on('click', function(event){     
    event.preventDefault();
    smoothScrollingTo(this.hash);
});
$(document).ready(function(){
  smoothScrollingTo(location.hash);
});

href^=\\#说明:

^表示它匹配包含# char的内容。因此，只匹配锚，以确保它是一个链接到同一页面(感谢Peter Wong的建议)。 \\是因为#在CSS选择器中是一个特殊字符，所以我们必须转义它。

本机支持在哈希id滚动上平滑滚动。

html {
  scroll-behavior: smooth;
}

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
    }
}

$(function() {
  $('a[href*=#]:not([href=#])').click(function() {
    if (location.pathname.replace(/^\//,'') == this.pathname.replace(/^\//,'') && location.hostname == this.hostname) {
      var target = $(this.hash);
      target = target.length ? target : $('[name=' + this.hash.slice(1) +']');
      if (target.length) {
        $('html,body').animate({
          scrollTop: target.offset().top
        }, 1000);
        return false;
      }
    }
  });
});

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;
