单击锚链接时平滑滚动

Question

我的页面上有几个超链接.用户在访问我的帮助部分时将阅读的常见问题解答.

使用Anchor链接,我可以使页面滚动到锚点并引导用户.

有没有办法让滚动顺畅？

但请注意他正在使用自定义JavaScript库.也许jQuery提供像这样的东西？

Answer 1

2018年4月更新:现在有一种本地方式可以做到这一点:

document.querySelectorAll('a[href^="#"]').forEach(anchor => {
    anchor.addEventListener('click', function (e) {
        e.preventDefault();

        document.querySelector(this.getAttribute('href')).scrollIntoView({
            behavior: 'smooth'
        });
    });
});

目前仅在最前沿的浏览器中支持此功能.

对于较旧的浏览器支持,您可以使用此jQuery技术:

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

    $('html, body').animate({
        scrollTop: $($.attr(this, 'href')).offset().top
    }, 500);
});

这里是小提琴:http://jsfiddle.net/9SDLw/

如果您的目标元素没有ID,并且您通过它链接到它name,请使用以下命令:

$('a[href^="#"]').click(function () {
    $('html, body').animate({
        scrollTop: $('[name="' + $.attr(this, 'href').substr(1) + '"]').offset().top
    }, 500);

    return false;
});

为了提高性能,您应该缓存该$('html, body')选择器,以便每次单击锚点时都不会运行它:

var $root = $('html, body');

$('a[href^="#"]').click(function () {
    $root.animate({
        scrollTop: $( $.attr(this, 'href') ).offset().top
    }, 500);

    return false;
});

如果要更新URL,请在animate回调中执行此操作:

var $root = $('html, body');

$('a[href^="#"]').click(function() {
    var href = $.attr(this, 'href');

    $root.animate({
        scrollTop: $(href).offset().top
    }, 500, function () {
        window.location.hash = href;
    });

    return false;
});

Answer 2

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);
});

说明href*=\\#:

• *意味着它匹配包含#char的内容.因此只匹配锚点.有关此含义的更多信息,请参见此处
• \\是因为它#是css选择器中的一个特殊字符,所以我们必须将其转义.

Answer 3

CSS3的新热点.这比本页面上列出的每种方法都容易得多,不需要Javascript.只需在css中输入以下代码,突然链接指向您自己页面内的位置就会有一个平滑的滚动动画.

html{scroll-behavior:smooth}

之后,任何指向div的链接都会顺利地滑向这些部分.

<a href="#section">Section1</a>

顺便说一下,我花了好几个小时试图让它发挥作用.在一些不起眼的评论部分找到了解决方案.它有缺陷,不适用于某些标签.没有在体内工作.当我把它放在CSS文件中的html {}时,它终于奏效了.

Answer 4

不需要任何js只需使用scroll-behavior: smooth at html标签就是这样

html{
scroll-behavior: smooth;
}

Answer 5

$('a[href*=#]').click(function(event){
    $('html, body').animate({
        scrollTop: $( $.attr(this, 'href') ).offset().top
    }, 500);
    event.preventDefault();
});

这对我来说很完美

Answer 6

我很惊讶没有人发布了一个原生解决方案,它还负责更新浏览器位置哈希以匹配.这里是:

let anchorlinks = document.querySelectorAll('a[href^="#"]')
 
for (let item of anchorlinks) { // relitere 
    item.addEventListener('click', (e)=> {
        let hashval = item.getAttribute('href')
        let target = document.querySelector(hashval)
        target.scrollIntoView({
            behavior: 'smooth',
            block: 'start'
        })
        history.pushState(null, null, hashval)
        e.preventDefault()
    })
}

Answer 7

我建议你制作这个通用代码:

$('a[href^="#"]').click(function(){

var the_id = $(this).attr("href");

    $('html, body').animate({
        scrollTop:$(the_id).offset().top
    }, 'slow');

return false;});

Answer 8

只有CSS

html {
    scroll-behavior: smooth !important;
}

您只需要添加此内容。现在，您的内部链接滚动行为将像流一样平滑。

要了解详细信息，请阅读本文

Answer 9

$(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;
      }
    }
  });
});

Answer 10

有关平滑滚动方法的更全面列表，请参阅我的回答此处。

您可以使用window.scroll()withbehavior: smooth并将top其设置为锚标记的偏移顶部，以确保锚标记位于视口的顶部。

document.querySelectorAll('a[href^="#"]').forEach(a => {
    a.addEventListener('click', function (e) {
        e.preventDefault();
        var href = this.getAttribute("href");
        var elem = document.querySelector(href)||document.querySelector("a[name="+href.substring(1, href.length)+"]");
        //gets Element with an id of the link's href 
        //or an anchor tag with a name attribute of the href of the link without the #
        window.scroll({
            top: elem.offsetTop, 
            left: 0, 
            behavior: 'smooth' 
        });
        //if you want to add the hash to window.location.hash
        //you will need to use setTimeout to prevent losing the smooth scrolling behavior
       //the following code will work for that purpose
       /*setTimeout(function(){
            window.location.hash = this.hash;
        }, 2000); */
    });
});

演示：

document.querySelectorAll('a[href^="#"]').forEach(a => {
    a.addEventListener('click', function (e) {
        e.preventDefault();
        var href = this.getAttribute("href");
        var elem = document.querySelector(href)||document.querySelector("a[name="+href.substring(1, href.length)+"]");
        //gets Element with an id of the link's href 
        //or an anchor tag with a name attribute of the href of the link without the #
        window.scroll({
            top: elem.offsetTop, 
            left: 0, 
            behavior: 'smooth' 
        });
        //if you want to add the hash to window.location.hash
        //you will need to use setTimeout to prevent losing the smooth scrolling behavior
       //the following code will work for that purpose
       /*setTimeout(function(){
            window.location.hash = this.hash;
        }, 2000); */
    });
});

a, a:visited{
  color: blue;
}

section{
  margin: 500px 0px; 
  text-align: center;
}

您只需将 CSS 属性设置scroll-behavior为smooth（大多数现代浏览器都支持）即可消除对 Javascript 的需要。

<a href="#section1">Section 1</a>
<br/>
<a href="#section2">Section 2</a>
<br/>
<a href="#section3">Section 3</a>
<br/>
<a href="#section4">Section 4</a>

Answer 11

使用 JQuery：

$('a[href*=#]').click(function(){
  $('html, body').animate({
    scrollTop: $( $.attr(this, 'href') ).offset().top
  }, 500);
  return false;
});

Answer 12

There is a css way of doing this using scroll-behavior. Add the following property.

    scroll-behavior: smooth;

And that is it. No JS required.

    scroll-behavior: smooth;

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;
}

PS: please check the browser compatibility.

Answer 13

这里已经有了很多好的答案-但是它们都缺少必须排除空锚的事实。否则，一旦单击空锚，这些脚本就会生成JavaScript错误。

我认为正确的答案是这样的：

$('a[href*=\\#]:not([href$=\\#])').click(function() {
    event.preventDefault();

    $('html, body').animate({
        scrollTop: $($.attr(this, 'href')).offset().top
    }, 500);
});
