Bootstrap 3 Navbar切换 - 折叠但不显示按钮

Question

我不知道我在这里做错了什么,但我认为这是一件非常愚蠢的事情.

我在Umbraco 6.0.5中使用Bootstrap 3并且我无法让切换工作调整大小 - 在770px宽度下导航器折叠但是没有按钮可以切换它,或者更确切地说是存在的东西,如代码和Firebug中所示,但在Chrome和Firefox中没有看到(尚未尝试IE).

下面有一个小提琴和代码.我使用http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js,http://netdna.bootstrapcdn.com/bootstrap/3.0.3/js/bootstrap.小提琴中的min.js和http://netdna.bootstrapcdn.com/bootstrap/3.1.0/css/bootstrap.min.css.

更新 - 所以,我试图改变数据目标(并改变了小提琴)到#main-nav和id到main-nav,没有快乐.我尝试在按钮> span元素中添加一个破折号字符,它可以工作.也就是说,破折号显示,我可以切换菜单.但是图标栏在哪里？

  <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#main-nav">
    <span class="sr-only">Toggle navigation</span>
    <span class="icon-bar">-</span>
    <span class="icon-bar">-</span>
    <span class="icon-bar">-</span>
  </button>

Answer 1

并<nav class="navbar">改为<nav class="navbar navbar-default">

Answer 2

Bootstrap - 切换按钮不会在移动视图中显示

FIX:在以下位置进行以下更改:bootstrap.min.css

这将修复Toggle Button的外边框

.navbar-toggle
{
    position:relative;
    float:right;
    padding:9px 10px;
    margin-top:8px;
    margin-right:15px;
    margin-bottom:8px;
    background-color:transparent;
    background-image:none;
    border-radius:4px
}

加

border:1px solid #444;

(更改颜色代码以符合您的设计)

.navbar-toggle
{
    position:relative;
    float:right;
    padding:9px 10px;
    margin-top:8px;
    margin-right:15px;
    margin-bottom:8px;
    background-color:transparent;
    background-image:none;
    border:1px solid #444;          /* added line */
    border-radius:4px
}

这样可以修复切换按钮的水平线

.icon-bar
{
    display:block;
    width:22px;
    height:2px;
    border-radius:1px;
}

加

border:1px solid #444;

(更改颜色代码以符合您的设计)

.icon-bar
{
    display:block;
    width:22px;
    height:2px;
    border-radius:1px;
    border:1px solid #444;
}
