我希望我的网站在单击网页中的向右箭头时侧向滚动。我制作了一个未完成的小脚本，但它没有按预期工作。在脚本中，该速率应每 10 毫秒降低一次，从而导致网页侧向滚动。稍后我将添加一个功能，以在达到所需边距时停止边滚动。这是代码：

<!DOCTYPE HTML>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>Untitled Document</title>
<style type="text/css">
body {
    background-image:url(ios-linen.jpg); 
    overflow:hidden;
}
div.length {
    width:10000px;
}
div.container {
    position:fixed;
    top:50%;
    left:50%;
    margin-top:-300px;
    margin-left:-450px;
}
div.content {
    display:inline-block;
    height:600px;
    width:900px;
    background-color:#CCC;
    opacity:0.3;
    border-radius:20px;
    position:absolute;

}
div.info {
    z-index:1;
    position:inherit;
    width:870px;

}
div.arrow {

    -moz-transition:all .5s;

    margin-top:-200px;
    left:5%;
}
#right {
    top:50%;
    margin-top:-200px;
    left:80%;
}
</style>
<script type="text/javascript">
function right() {
    var rate = 0;
    setInterval(function() {
            document.getElementById('length').style.marginLeft += rate;
            rate--;
    }, 10);
}

它看起来不滚动的原因是因为页面上的所有其他 DIV 都position:fixed; 包含 DIVlength可能正在移动，但箭头和灰色背景的东西永远不会通过更改length元素的填充来移动。

要验证这一点，请向 DIV 添加一个“监视”length并在控制台中检查它。

本质上你应该使用 $('html').get(0).scrollLeft 来改变位置。

这是一个 js fiddle 来帮助你。

http://jsfiddle.net/UqbPQ/17/

var direction = 0;
var speed = 2;
$('#l').click(function() {
    direction = -speed;
});
$('#p').click(function() {
    direction = 0;
});
$('#r').click(function() {
    direction = speed;
});
window.setInterval(function() {
    var elm = $('html').get(0);
    var pos = elm.scrollLeft;
    pos += direction;
    elm.scrollLeft = pos;
    $('#p').text(elm.scrollLeft);
}, 10);
body {
    background-color: yellow;
    width: 100%;
    height: 100%;
    margin: 0px;
    padding 0px;
    overflow: hidden;
}
div.length {
    background-color: aqua;
    top: 0px;
    left: 0px;
    width:10000px;
    height: 90%;
