我创建了一个显示所有行的仪表板，但我想要一个自动滚动，它会慢慢向下滚动页面底部，然后慢慢滚动回顶部并重复。我已经用谷歌搜索了这个并且无法获得工作代码。我一直在寻找 jQuery 代码，但什么都可以。

因为页面会一直调整它不能有固定的高度滚动。

不确定您是否需要更多信息，但如果需要，我会更新这个问题。

问候开局

你可以使用这样的东西。

//run instantly and then goes after (setTimeout interval)

    $("html, body").animate({ scrollTop: $(document).height() }, 4000);
    setTimeout(function() {
       $('html, body').animate({scrollTop:0}, 4000); 
    },4000);
  var scrolltopbottom =  setInterval(function(){
         // 4000 - it will take 4 secound in total from the top of the page to the bottom
    $("html, body").animate({ scrollTop: $(document).height() }, 4000);
    setTimeout(function() {
       $('html, body').animate({scrollTop:0}, 4000); 
    },4000);

    },8000);

​//Use this to stop the scroller -> clearInterval(scrolltopbottom);

你应该试试这个以获得更好的结果

//run instantly and then goes after (setTimeout interval)

$("html, body").animate({ scrollTop: $(document).height() }, 4000);

setTimeout(function() {
   $('html, body').animate({scrollTop:0}, 4000); 
},4000);


setInterval(function(){
     // 4000 - it will take 4 secound in total from the top of the page to the bottom
$("html, body").animate({ scrollTop: $(document).height() }, 4000);
setTimeout(function() {
   $('html, body').animate({scrollTop:0}, 4000); 
},4000);
    
},8000);


$('html, body').mouseover(function(e) {
$(this).stop(true);
      
    }).mouseout(function() {
         $(this).stop(false);
    });

在这里，这应该很好用，只需将 5000 更改为以 ms 为单位的时间即可调整速度。

http://jsfiddle.net/BDc6S/3/

function scrollDown(el) {
    el.animate({
        scrollTop: el[0].scrollHeight
    }, 5000, function() {
        scrollUp(el)
    });
};

function scrollUp(el) {
    el.animate({
        scrollTop: 0
    }, 5000, function() {
        scrollDown(el);
    });
};

scrollDown($("html,body"));​

function doSomething() {
  $(document).scrollTop($(document).height());
}
setInterval(doSomething, 5000);

这将每 5 秒滚动到页面底部。如果您有像 facebook 这样基于用户滚动的自动加载内容，这将很有用。
