我在iframe中加载视图。但是当它呈现带有数据表的视图时，滚动条没有显示，因此我无法在IFrame中看到表的其余部分。我的代码如下：
view_navigation：
<style>
.scroller {
position: fixed;
right: 0;
bottom: 0;
left: 0;
top: 0;
-webkit-overflow-scrolling: touch;
overflow-y: scroll;
}
/* The style for iframe varies */
.scroller iframe {
height: 250px;
width: 100%;
}
</style>
<script>
function go(location) {
document.getElementById('main_frame').src = location;
}
</script>
<header class="navbar navbar-inverse navbar-fixed-top" role="navigation">
<div class="navbar-header">

<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<a href="#" class="navbar-brand">Pier Capitan</a>
<nav class="collapse navbar-collapse" role="navigation">
<ul class="nav navbar-nav">
<?php foreach($links as $link){ ?>
<li>
<a href="javascript:void(0)" onclick="go('<?php echo base_url().$link->access_rights ?>')"><?php echo strtoupper($link->access_rights) ?></a>
</li>
<?php } ?>
</ul>
</nav><!-- end of navbar collapse -->
</div><!-- end of navbar header -->
</header>
<body style="overflow-y:scroll;"">

“view_navigation”包含加载“purchase_view”的IFrame。 非常感谢您的帮助。

这是什么请正确关闭标签：
<div class="col-md-12 scroller">
<body style="overflow-y:scroll;>
<iframe src="about:blank" id="main_frame" frameborder="0" scrolling="yes"></iframe>
</div>
</body>
试试这段代码：
<body style="overflow-y:scroll;>
<div class="col-md-12">
<div class=" scroller">
<iframe src="about:blank" id="main_frame" frameborder="0" scrolling="yes"></iframe>
</div>
</div>
</body>
.scroller iframe {
height: 250px;
width: 100%;
}
