javascript - 如何向下滚动 - JQuery

Question

我不是程序员，但我使用下面的代码将页面滚动到顶部。

如何调整它以向下滚动？

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.min.js"></script>

<a class="btnMedio" href="javascript:;">
    <img src="http://desmond.imageshack.us/Himg41/scaled.php?server=41&filename=deixeseuemail.png&res=landing"/>
</a>

<script>
    $('.btnMedio').click(function(){
        $('html, body').animate({scrollTop:1000},'50');
    });
</script>

Answer 1

$('.btnMedio').click(function(event) {
    // Preventing default action of the event
    event.preventDefault();
    // Getting the height of the document
    var n = $(document).height();
    $('html, body').animate({ scrollTop: n }, 50);
//                                       |    |
//                                       |    --- duration (milliseconds) 
//                                       ---- distance from the top
});
