自定義滾動條

Question

在我的應用程序中，應該將滾動條的位置更改爲自定義滾動條。是否有任何方法可以在CSS中對滾動條進行樣式設置。如果不是，請提供關於自定義滾動條的任何建議。

我已經看到了自定義滾動條的jquery插件，但我需要更改自定義滾動條的每個位置。相反，是否有任何方法可以在一個位置更改應該影響滾動條將進入的所有位置我的應用程序。

Answer 1

您可以在WebKit和older IE s中設置滾動條的樣式。

要影響所有滾動條，您應該可以使用選擇器，如body, textarea, .any-other-element-with-overflow-scroll。

使用自定義滾動條時，請考慮可能的usability issues。

Answer 2

我開發了一個custom scrollbar library named SimpleScrollbar。

它不依賴於任何其他庫/框架，並且它在gzip和縮小之後小於1KB。

它使用原生滾動，所以沒有黑客，性能很棒。

你只需要在你的網頁庫，並在你想滾動任何DIV使用ss-container屬性。活生生的例子：

<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>

它適用於所有現代瀏覽器（Firefox，鉻，歌劇，Safari瀏覽器，邊緣），並在IE10和IE11。你也可以在IE9中使用它，包括一個classList填充。

也支持所有的Android，iOS和Windows Phone瀏覽器。

如果你想自動找出所有已經有一個滾動條的元素，你可以做這樣的事情：

// After all the content in your page has loaded 
document.addEventListener('DOMContentLoaded', function() { 
    // Get all elements in your page 
    var elements = document.querySelectorAll('*'), el; 
    for (var i = 0; i < elements.length, el = elements[i]; i++) { 
    // If the scrollheight is higher than the clientheight, it's because it has a scrollbar 
    if (el.scrollHeight > el.clientHeight) { 
     SimpleScrollbar.initEl(el); // turn the element into a SimpleScrollbar one 
    } 
    } 
});
