【问题描述】：
我对 Ruby on Rails 有一个看法，它运行良好，但我的问题是页面加载需要相当长的时间。这是部分代码：
主标签
<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">
<br />
<div class="col-lg-6 pull-right">
<div class="input-group pull-right" id="searchDrafts">
<input type="text" class="form-control" placeholder="Search for">
<span class="input-group-btn">
<button class="btn btn-default" type="button">
<span class="glyphicon glyphicon-search" aria-hidden="true"></span>
</button>
</span>
</div><!-- /input-group -->
<div class="dropdown">
<button class="btn btn-default dropdown-toggle pull-right" type="button" id="dropdownDrafts" data-toggle="dropdown" aria-haspopup="true" aria-expanded="true">
Filter by
<span class="caret"></span>
</button>
<ul class="dropdown-menu" aria-labelledby="dropdownMenu1">
<li><a href="#">Sent to</a></li>
<li><a href="#">Subject</a></li>
<li><a href="#">Date</a></li>
</ul>
</div>
</div><!-- /.col-lg-6 -->

还有 5 个与此相同的选项卡，我觉得加载需要一段时间的原因是，每次加载该页面时，它会加载所有内容，而不是我当前所在的选项卡.这成为一个大问题，尤其是当我想对数据进行分页并且每个页面都加载所有选项卡时。有没有办法更好地优化这段代码？谢谢。

您可以使用 ajax 加载每个选项卡，然后在需要时加载。 （见stackoverflow.com/questions/27485566/…）
