Question

我正在寻找创建滚动功能的资源，例如在这些网站上找到的功能：
Outpost Journal
Unfold

滚动条点击页面底部后，我希望它循环回到顶部。我对无限卷轴很熟悉，这不是我想要的。我还发现脚本会将相同的内容写入/添加到页面底部，但没有一个循环回到页面顶部。

Answer 1

试试这个：

   $('document').ready(function() {
             $(document).scroll(function(){
             if(document.documentElement.clientHeight + 
             $(document).scrollTop() >= document.body.offsetHeight )$(document).scrollTop(0);
             });
          });

Answer 2

这里是一个复制身体的解决方案，因此可以在某一点同时看到底部和顶部，因此过渡更平滑。

$('document').ready(function() {

     // We need to duplicate the whole body of the website so if you scroll down you can see both the bottom and the top at the same time. Before we do this we need to know the original height of the website.
     var origDocHeight = document.body.offsetHeight;

     // now we know the height we can duplicate the body    
     $("body").contents().clone().appendTo("body");


     $(document).scroll(function(){ // detect scrolling

         var scrollWindowPos = $(document).scrollTop(); // store how far we have scrolled

         if(scrollWindowPos >= origDocHeight ) { // if we scrolled further then the original doc height
             $(document).scrollTop(0); // then scroll to the top
         }       
     });

 });

如果您想在两个方向上进行无限滚动，请使用

if (document.documentElement.clientHeight + $(window).scrollTop() >= $(document).height()) {
    $(document).scrollTop(0)
} else if ($(window).scrollTop() < 0) {
    $(document).scrollTop($(document).height())
}

（我知道这是一个迟到的回复，但它仍然可以帮助像我这样的用户像谷歌这样的东西）

mrida的答案导致我的浏览器无法滚动，这是一个适合我的修改版本：

  $('document').ready(function() {
    $(document).scroll(function(){
      if (document.documentElement.clientHeight + $(window).scrollTop() >= $(document).height()) {
        $(document).scrollTop(0);
      }
    });
  });

Answer 5

从 @ clankill3r 的答案中分出来，创建两个正文副本，前置并附加到原始正文，然后你可以向两个方向滚动页面无穷无尽。

$('document').ready(function() {

    var origDocHeight = document.body.offsetHeight;

    var clone=$("body").contents().clone();
    clone.appendTo("body");
    clone.prependTo("body");

    $(document).scroll(function(){ 

        var scrollWindowPos = $(document).scrollTop(); 

        if(scrollWindowPos >= origDocHeight ) { 
            $(document).scrollTop(0); 
        }
        if(scrollWindowPos <= 0 ) { 
             $(document).scrollTop(origDocHeight); 
         }        
    });
});

向后添加循环滚动，升级@ clankill3r答案。它应该是这样的。

$('document').ready(function() {

 // We need to duplicate the whole body of the website so if you scroll down you can see both the bottom and the top at the same time. Before we do this we need to know the original height of the website.
 var origDocHeight = document.body.offsetHeight;

 // now we know the height we can duplicate the body    
 $("body").contents().clone().appendTo("body");


 $(document).scroll(function(){ // detect scrolling

     var scrollWindowPos = $(document).scrollTop(); // store how far we have scrolled

     if(scrollWindowPos >= origDocHeight ) { // if we scrolled further then the original doc height
         $(document).scrollTop(scrollWindowPos + origDocHeight); // then scroll to the top
     } else if (scrollWindowPos == 0) { // if we scrolled backwards
         $(document).scrollTop(origDocHeight);
     }
 });
});

我水平使用它并且工作得很好。希望有人觉得它很有用。

发布了一个类似的问题：https://stackoverflow.com/a/65953934/7474712 并通过这支笔找到了答案：https://codepen.io/vincentorback/pen/zxRyzj

代码如下：

<style>

html,
body {
  height: 100%;
  overflow: hidden;
}
  
.infinite {
  overflow: auto;
  -webkit-overflow-scrolling: touch;
}

.clone {
  height: 50vw;
}
  
</style>

<script>

    var doc = window.document,
    context = doc.querySelector('.infinite'),
    clones = context.querySelectorAll('.clone'),
    disableScroll = false,
    scrollHeight = 0,
    scrollPos = 0,
    clonesHeight = 0,
    i = 0;

    function getScrollPos () {
      return (context.pageYOffset || context.scrollTop) - (context.clientTop || 0);
    }

    function setScrollPos (pos) {
      context.scrollTop = pos;
    }

    function getClonesHeight () {
      clonesHeight = 0;

      for (i = 0; i < clones.length; i += 1) {
        clonesHeight = clonesHeight + clones[i].offsetHeight;
      }

      return clonesHeight;
    }

    function reCalc () {
      scrollPos = getScrollPos();
      scrollHeight = context.scrollHeight;
      clonesHeight = getClonesHeight();

      if (scrollPos <= 0) {
        setScrollPos(1); // Scroll 1 pixel to allow upwards scrolling
      }
    }

    function scrollUpdate () {
      if (!disableScroll) {
        scrollPos = getScrollPos();

        if (clonesHeight + scrollPos >= scrollHeight) {
          // Scroll to the top when you’ve reached the bottom
          setScrollPos(1); // Scroll down 1 pixel to allow upwards scrolling
          disableScroll = true;
        } else if (scrollPos <= 0) {
          // Scroll to the bottom when you reach the top
          setScrollPos(scrollHeight - clonesHeight);
          disableScroll = true;
        }
      }

      if (disableScroll) {
        // Disable scroll-jumping for a short time to avoid flickering
        window.setTimeout(function () {
          disableScroll = false;
        }, 40);
      }
    }

    function init () {
      reCalc();

      context.addEventListener('scroll', function () {
        window.requestAnimationFrame(scrollUpdate);
      }, false);

      window.addEventListener('resize', function () {
        window.requestAnimationFrame(reCalc);
      }, false);
    }

    if (document.readyState !== 'loading') {
      init()
    } else {
      doc.addEventListener('DOMContentLoaded', init, false)
    }

</script>

连续循环页面（不是无限滚动）
