Question

是否有自定义滚动条的库/插件支持高度100％属性或仅支持百分比？我已经测试了几十个jQuery滚动条插件，但没有固定高度，它们似乎都没有正常工作。

Answer 1

您可以使用

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

并将您尝试使用的插件的像素高度设置为

(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和width（）方法而不是innerHeight（）或innerWidth（），因为内部方法包括元素填充但不包含边框。

如果需要滚动条缩放到高度或宽度更改，请在jQuery resize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);

Answer 2

您已经测试了十几个插件，但是错过了一些：尝试使用jQuery Scrollbar，这不需要设置高度。此外，可以使用父容器的max-height或px中的标准css %值限制高度。

Answer 3

我开发了custom scrollbar library named SimpleScrollbar。

它不依赖于任何其他库/框架，并且在gzip和minification之后它不到1KB。

它使用原生滚动，所以没有黑客，性能很棒。

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

<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. Ut enim ad minima veniam, quis nostrum exercitationem ullam corporis suscipit laboriosam, nisi ut aliquid ex ea commodi consequatur? 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>

适用于所有现代浏览器（Firefox，Chrome，Opera，Safari，Edge）以及IE10和IE11。您也可以通过包含classList polyfill在IE9中使用它。

支持所有Android，iOS和Windows Phone浏览器。

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