我有一个Ruby on Rails的视图，它工作正常，但我的问题是，它需要相当一段时间才加载页面。这是一些代码：优化前端代码
主要选项卡
<div class="tab-content">
<div class="tab-pane fade in active" id="tabconstituent">
<h3>Constituent Database</h3>
<ul class="nav nav-tabs">
<li class="active"><a href="#tabconstinbox" data-toggle="tab">Inbox</a></li>
<li><a href="#tabconstsent" data-toggle="tab">Sent</a></li>
</ul>
<div class="tab-content">
<div role="presentation" class="tab-pane fade in active" id="tabconstinbox">
<div class="container-fluid">

有5个选项卡是完全相同的，我有一种感觉，为什么它需要一段时间来加载的原因是因为，每次一个加载页面，加载所有内容，而不是我目前使用的选项卡。这成为一个大问题，特别是当我想分页数据和每个页面加载所有标签时。有什么方法可以更好地优化此代码？谢谢。
使其当你需要它你可以加载每个标签使用Ajax，然后。 （见http://stackoverflow.com/questions/27485566/rails-4-ajax-load-content-in-bootstrap-tab） – siegy22
