我正在尝试使用jQuery使左箭头和右箭头在单击时左右滚动+ 50px，但它似乎只是将页面重置为向左滚动0。

这是我的 HTML：

<div id="parallax">
    <a href="#" id="test"></a>
</div>

这是我的脚本：

$(document).ready(function(){
    $("#test").click(function(){
        $("#parallax").scrollLeft(5000);
    });
});

任何帮助或见解将不胜感激。

您需要阻止<a>元素的默认操作，因为 ahref="#"将始终滚动到顶部：

$(document).ready(function(){
    $("#test").click(function(e){
        e.preventDefault();
        $('body').scrollLeft(5000);
    });
});​

正如所承诺的，这是我编写的演示。这是一个粗略的草案，可以使用一些清洁。我还删除了一些与公司相关的东西，可能会有一两种风格引用它们，但除此之外它应该做你想做的事。

注意：这个演示是为 Chrome 设计的（样式包括只有 chrome 属性的 CSS3 效果 - 我写得很快，并不是为了兼容性而写的 - 随意更改和删除/添加任何必要的样式以使其在其他浏览器中兼容）

                The demo below is intended to illustrate the use of jQuery and CSS to create a slide

                onto multiple lines. The scripting involved is very light weight, and can easily
                be wrapped up into a jQuery plugin.

请找到以下链接。我希望它有助于解决这个问题。 

$('.left').click(function(){

  $('#container').scrollLeft(0);
}); 
var bb=0;
$('.right').click(function(){
bb++;
    $('#container').scrollLeft(bb*50);

});
