无限滚动允许您加载其他内容，并在页面接近底部时执行所需的操作.
以下HTML布局显示无限滚动 : 去;
<div class = "page"> <div class = "page-content infinite-scroll" data-distance = "100"> ... </div> </div>
以上布局包含以下类 :
页面内容无限滚动 : 它用于无限滚动容器.
data-distance : 此属性允许您配置从页面底部(以px为单位)到触发无限滚动事件的距离，其默认值为 50 px.
如果你想在页面顶部使用无限滚动，你需要在"page-content"中添加额外的"infinite-scroll-top"类 :
<div class = "page"> <div class = "page-content infinite-scroll infinite-scroll-top"> ... </div> </div>
无限 : 它用于在页面滚动到达底部的指定距离时触发.它将是 div class ="page-content infinite-scroll"的目标.
有两个App的方法可用于无限滚动容器和减号;
要将无限滚动事件侦听器添加到指定的HTML容器，请使用以下方法 :
myApp.attachInfiniteScroll(container)
您可以使用以下方法删除指定HTML容器中的无限滚动事件侦听器 :
myApp.detachInfiniteScroll(container)
其中参数是必需的用作无限滚动容器的 HTMLElement 或 string 的选项.
以下示例演示了当页面滚动接近底部和负号时加载附加内容的无限滚动;

</html>让我们执行以下步骤，看看上面给出的代码如何工作 : 去;
将上面给出的HTML代码保存为服务器根文件夹中的 infinite_scroll.html 文件.
将此HTML文件打开为http://localhost/infinite_scroll.html，输出显示如下.
该示例允许在页面滚动到底部指定距离时加载其他内容.
