高度 100% 自定义滚动条

你可以使用

var objHeight = window.innerHeight;// to get the pixel height

并设置您尝试使用的插件的像素高度

(objHeight.toString() + "px")

要使用 jQuery 获取其他 DOM 元素的 innerHeight 或 innerWidth，请尝试 jQuery 自己的 innerWidth/innerHeight(( 方法：http://api.jquery.com/innerHeight/。

注意：如果对象上有边框，请使用普通的 height and width(( 方法，而不是 innerHeight(( 或 innerWidth((，因为内部方法包括元素填充，但不包括边框。

如果需要滚动条缩放到高度或宽度变化，请在 jQuery 调整大小事件上创建回调：

var resizeFn = function() {
//do resize calcs with getting height and widths and 
// setting plugin updates to new height and width
}
$(window).resize(functionName);

你已经测试了十几个插件，但错过了一些：尝试使用jQuery滚动条，它不需要设置高度。此外，可以使用父容器px或%中的标准 css max-height值来限制高度。

我开发了一个名为 SimpleScrollbar 的自定义滚动条库。

它不依赖于任何其他库/框架，并且在 gzip 和缩小后小于 1KB。

它使用本机滚动，因此没有黑客攻击，性能很棒。

您只需要在页面中包含库，并在要使其可滚动的任何div 中使用 ss-container 属性。现场示例：

<link href="http://buzinas.github.io/simple-scrollbar/simple-scrollbar.css" rel="stylesheet"/>
<div style="height: 180px; width: 200px; display: inline-block;" ss-container>
  <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.</p>
</div>
<section style="height: 180px; width: 300px; display: inline-block;" ss-container>
  <p>Sed ut perspiciatis unde omnis iste natus error sit voluptatem accusantium doloremque laudantium, totam rem aperiam, eaque ipsa quae ab illo inventore veritatis et quasi architecto beatae vitae dicta sunt explicabo. Nemo enim ipsam voluptatem quia voluptas sit aspernatur aut odit aut fugit, sed quia consequuntur magni dolores eos qui ratione voluptatem sequi nesciunt. Neque porro quisquam est, qui dolorem ipsum quia dolor sit amet, consectetur, adipisci velit, sed quia non numquam eius modi tempora incidunt ut labore et dolore magnam aliquam quaerat voluptatem.

Quis autem vel eum iure reprehenderit qui in ea voluptate velit esse quam nihil molestiae consequatur, vel illum qui dolorem eum fugiat quo voluptas nulla pariatur?</p>
      <p>But I must explain to you how all this mistaken idea of denouncing pleasure and praising pain was born and I will give you a complete account of the system, and expound the actual teachings of the great explorer of the truth, the master-builder of human happiness. No one rejects, dislikes, or avoids pleasure itself, because it is pleasure, but because those who do not know how to pursue pleasure rationally encounter consequences that are extremely painful. Nor again is there anyone who loves or pursues or desires to obtain pain of itself, because it is pain, but because occasionally circumstances occur in which toil and pain can procure him some great pleasure. To take a trivial example, which of us ever undertakes laborious physical exercise, except to obtain some advantage from it? But who has any right to find fault with a man who chooses to enjoy a pleasure that has no annoying consequences, or one who avoids a pain that produces no resultant pleasure?</p>

只要父容器定义了高度，它就支持您询问的height: 100%，例如：http://jsfiddle.net/z19w2Lfa/
