Question

我创建了一个回显所有行的仪表板，但我想要一个自动滚动，它将慢慢向下滚动页面底部，然后慢慢滚动回到顶部并重复。我用Google搜索了这个，但无法获得正常工作的代码。我一直在寻找jQuery代码，但任何事情都可以。

因为页面会一直调整，所以无法固定高度滚动。

不确定您是否需要更多信息，但如果您这样做，我将更新此问题。

此致开局

Answer 1

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);
    });

Answer 3

在这里，这应该运作良好，只需将5000改为以ms为单位的时间来调整速度。

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"));

Answer 4

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

这将每5秒滚动到页面底部。如果您有基于用户滚动的自动加载内容（如facebook），这将非常有用。

自动滚动到页面底部然后顶部并重复
