我的网站在我的 mac 和 iphone 上运行良好，但在 IE 中却不行。在 IE 中，一些导航栏功能不正确（即布局不正确，搜索框没有占位符文本，导航栏元素之一（收藏夹）看起来完全不同）。我不确定问题出在哪里

布局/application.html.erb 是

<!DOCTYPE html>
<html>
<head>
    <meta name="viewport" content="width=device-width, initial-scale=1.0">

    <%= analytics_init if Rails.env.production? %>
  <title>Guidelines for Me</title>

  <%= stylesheet_link_tag    "application", :media => "all" %>

  <%= javascript_include_tag "application" %>
  <link href="../assets/bootstrap-responsive.css" rel="stylesheet">
  <%= csrf_meta_tags %>

  <script type="text/javascript">
function clearDefault(el) {
if (el.defaultValue==el.value) el.value = ""
}
function clearText(){
    search = $('.search-query');
    if (search.defaultValue==search.value)
    search.value = ""
}
type="text/javascript">
$(document).ready(function() {
    $('.collapse').collapse();
}); 


</script>
</head>
<body>

    <div class="navbar navbar-inverse navbar-fixed-top">
        <div class="navbar-inner">
            <div class="container">

                </a>

                <% if Guideline.count % 100 ==0 %>
                    <%= link_to "#{Guideline.count}" " guidelinesforme - yay!", guidelines_path, :class => 'brand' %>

    <div class="container"> 
        <%= yield %>

</body>

</html>

我用过推特引导程序。

我确实添加了

<!-- HTML5 shim, for IE6-8 support of HTML5 elements -->
<!--[if lt IE 9]>
  <script src="http://html5shim.googlecode.com/svn/trunk/html5.js"></script>
<![endif]-->

在我之前，但似乎没有什么不同。

首先，直到 IE9 才支持占位符。但是您可以使用 javascript pollyfills 来启用占位符支持， 为此目的使用http://www.modernizr.com/ 。
