subnav栏与twitter引导折叠

Question

我使用twitter bootstrap和我的导航栏与折叠功能正常工作。

这是我的html代码：

<div class="subnav"> 
    <ul class="nav nav-pills"> 
     <li class="dropdown"> 
     <a href="#" data-toggle="dropdown" class="dropdown-toggle">Buttons <b class="caret"></b></a> 
     <ul class="dropdown-menu"> 
      <li class=""><a href="#buttonGroups">Button groups</a></li> 
      <li class=""><a href="#buttonDropdowns">Button dropdowns</a></li> 
     </ul> 
     </li> 
     <li class="dropdown"> 
     <a href="#" data-toggle="dropdown" class="dropdown-toggle">Navigation <b class="caret"></b></a> 
     <ul class="dropdown-menu"> 
      <li class=""><a href="#navs">Nav, tabs, pills</a></li> 
      <li class=""><a href="#navbar">Navbar</a></li> 
      <li class=""><a href="#breadcrumbs">Breadcrumbs</a></li> 
      <li class=""><a href="#pagination">Pagination</a></li> 
     </ul> 
     </li> 
     <li class=""><a href="#labels">Labels</a></li> 
     <li class=""><a href="#badges">Badges</a></li> 
     <li class=""><a href="#typography">Typography</a></li> 
     <li class=""><a href="#thumbnails">Thumbnails</a></li> 
     <li class=""><a href="#alerts">Alerts</a></li> 
     <li><a href="#progress">Progress bars</a></li> 
     <li><a href="#misc">Miscellaneous</a></li> 
    </ul> 
    </div> 

这是我bootstrap_and_overrides.css.scss

$iconSpritePath: asset-url('glyphicons-halflings.png', image); 
$iconWhiteSpritePath: asset-url('glyphicons-halflings-white.png', image); 
@import "bootstrap"; 
body { padding-top: 40px; 
     .navbar .brand {padding: 10px 20px; } 
     background: url("background.png") repeat scroll 0 0 #EEEEEE; 


.subnav { 
    background-color: #EEEEEE; 
    background-repeat: repeat-x; 
    border: 1px solid #E5E5E5; 
    border-radius: 4px 4px 4px 4px; 
    height: 36px; 



      .nav > li > a { 
         border-left: 1px solid #F5F5F5; 
         border-radius: 0 0 0 0; 
         border-right: 1px solid #E5E5E5; 
         margin: 0; 
         padding-bottom: 11px; 
         padding-top: 11px; 
         } 
    } 

    .subnav-fixed { 
    /*important part*/ 
    left: 0; 
    position: fixed; 
    right: 0; 
    top: 40px; 
    z-index: 1020; 
    /*design stuff*/ 
    border-color: #D5D5D5; 
    border-radius: 0 0 0 0; 
    border-width: 0 0 1px; 
    box-shadow: 0 1px 0 #FFFFFF inset, 0 1px 5px rgba(0, 0, 0, 0.1); 
    background-color: #FFFFFF; 
    } 
} 
@import "bootstrap-responsive"; 

，这是我的js代码：

$(document).scroll(function(){ 
    // If has not activated (has no attribute "data-top" 
    if (!$('.subnav').attr('data-top')) { 
     // If already fixed, then do nothing 
     if ($('.subnav').hasClass('subnav-fixed')) return; 
     // Remember top position 
     var offset = $('.subnav').offset() 
     $('.subnav').attr('data-top', offset.top); 
    } 

    if ($('.subnav').attr('data-top') - $('.subnav').outerHeight() <= $(this).scrollTop()) 
     $('.subnav').addClass('subnav-fixed'); 
    else 
     $('.subnav').removeClass('subnav-fixed'); 
}); 

此外，我使用subnav栏，我的问题是，我的subnav栏未折叠。

正确subnav栏版本Twitter的引导：

如果你有这个问题，你可以解决这个问题，这样的：

在你JavaScript文件你必须添加此jQuery代码：

//subnav config 
$(function(){ 

    var $win = $(window); 
    var $nav = $('.subnav'); 
    var navTop = $('.subnav').length && $('.subnav').offset().top - 38; 
    var isFixed = 0; 

    processScroll(); 

    $win.on('scroll', processScroll); 

    function processScroll() { 
     console.log('test'); 
     var i, scrollTop = $win.scrollTop(); 
     if (scrollTop >= navTop && !isFixed) { 
      isFixed = 1; 
      $nav.addClass('subnav-fixed'); 
     } else if (scrollTop <= navTop && isFixed) { 
      isFixed = 0; 
      $nav.removeClass('subnav-fixed'); 
     } 
    }; 
}) 

在你的CSS文件或文件bootstrap_and_overrides.css.scss您可以添加以下代码：

/* Add additional stylesheets below 
-------------------------------------------------- */ 

/* Subnav */ 
.subnav { 
    width: 100%; 
    height: 36px; 
    background-color: #eeeeee; /* Old browsers */ 
    background-repeat: repeat-x; /* Repeat the gradient */ 
    background-image: -moz-linear-gradient(top, #f5f5f5 0%, #eeeeee 100%); /* FF3.6+ */ 
    background-image: -webkit-gradient(linear, left top, left bottom, color-stop(0%,#f5f5f5), color-stop(100%,#eeeeee)); /* Chrome,Safari4+ */ 
    background-image: -webkit-linear-gradient(top, #f5f5f5 0%,#eeeeee 100%); /* Chrome 10+,Safari 5.1+ */
