【问题描述】：

我想做的是像http://jsfiddle.net/kevinphpkevin/8tLdq/1/ 这样的事情，但是向下滚动而不是点击按钮。有什么建议吗？

$("html").scroll(function() 
    $('html, body').animate(
        scrollTop: $("#myDiv").offset().top
    , 2000);
);

【参考方案1】：

<div id="searchbycharacter">
<a class="searchbychar" href="#" data-target="numeric">0-9 |</a> 
<a class="searchbychar" href="#" data-target="A"> A |</a> 
<a class="searchbychar" href="#" data-target="B"> B |</a> 
<a class="searchbychar" href="#" data-target="C"> C |</a> 
... Untill Z
</div>

在 jquery 中这样写：

$(document).on('click','.searchbychar', function(event) 
event.preventDefault();
var target = "#" + this.getAttribute('data-target');
$('html, body').animate(
    scrollTop: $(target).offset().top
, 2000);
);

希望对你有帮助。

【参考方案2】：

你的代码应该是-

$(window).scroll(function() 
    $('html, body').animate(
        scrollTop: $("#myDiv").offset().top
    , 2000);
);

注意- 这不会特定于向下滚动。即使您尝试向上滚动也会触发此事件。

要让它只有在你向下滚动时才会发生-

var ls = 0;
$(window).scroll(function() 
    var st = $(window).scrollTop();
    if (st>ls) 
        $('html, body').animate(
            scrollTop: $("#myDiv").offset().top
        , 2000);
    
    ls = st;
);

【参考方案3】：

试试这个：

var lastScrollTop = 0;
$(window).scroll(function(event)
   var st = $(this).scrollTop();
   if (st > lastScrollTop)//when scrolled to down
		    $('html, body').animate(
		        scrollTop: $("#myDiv").offset().top
		    , 2000);
   else 
      // upscroll code
   
   lastScrollTop = st;
);

.div 
    min-height:1100px;
    background:red;

#myDiv 
    height:100px;
    background:blue;

    <p>Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.

It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).

 
        Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source. Lorem Ipsum comes from sections 1.10.32 and 1.10.33 of "de Finibus Bonorum et Malorum" (The Extremes of Good and Evil) by Cicero, written in 45 BC. This book is a treatise on the theory of ethics, very popular during the Renaissance. The first line of Lorem Ipsum, "Lorem ipsum dolor sit amet..", comes from a line in section 1.10.32.</p><p>Lorem Ipsum is simply dummy text of the printing and typesetting industry.
