我无法弄清楚如何制作这样的bootstrap列:

col 3 | col 4.5 | col 4.5 

该页面已呈现，但当我按下任何链接时它会出错。

ReferenceError: path is not defined

这是来自 server.js 的代码：

app.use(express.static('../build'));
app.get('*', (req, res)=> {
  const index = path.join(__dirname, '/', '../build', 'index.html' );
  res.sendFile(index);
});

提前致谢。

我的工作是使用javascript bootstrap 2.0.4

我正在寻找一种通过逻辑控制取消关闭模式的方法.但我找不到任何细节如何做到这一点

http://getbootstrap.com/javascript/#modals

像.NET这样的东西

OnWindowClosing(eventArguement) 
{ 
    if (shouldCancel) {
      eventArguement.Cancel = true; 
      return;
    }
}

我使用这样的代码生成我的文件

{% block head_stylesheets %}
    {% stylesheets
        filter='?uglifycss'
        '@MyBundle/Resources/public/less/myfile.less'
    %}
    <link href="{{ asset_url }}" type="text/css" rel="stylesheet" media="screen"/>
    {% endstylesheets %}
{% endblock head_stylesheets %}

它转储一个名为this的文件: c543k540_myfile_1.css

该文件由资产名称后跟文件名组成: {assetName}_{filename}.css

如何在输出中保留资产名称时自定义输出？

{% block head_stylesheets %}
    {% stylesheets
        output="css/mynewfilename.{assetName}.css"     // <--- Here
        filter='?uglifycss'
        '@MyBundle/Resources/public/less/myfile.less'
    %}
    <link href="{{ asset_url }}" type="text/css" rel="stylesheet" media="screen"/>
    {% endstylesheets %}
{% endblock head_stylesheets %}

更新澄清

我知道如果我使用name选项,在prod中它会编译到myouputname.css但是我想在debug/dev环境中有什么跟随下面的代码myfile_myouputname_1.css

{% block head_stylesheets %}
    {% stylesheets
        name="myouputname"     // <--- Here
        filter='?uglifycss'
        '@MyBundle/Resources/public/less/myfile.less'
    %}
    <link href="{{ asset_url }}" type="text/css" rel="stylesheet" …

我想知道如何在WebTestCase实例中检索实体管理器.

例如,查看在testrun期间是否真的在DB中创建了一个实体.

有什么想法吗？

我已经做了一个小提琴,说明了我目前面临的问题.所以每次我关闭并打开一个模态,shown.bs.modal也会多次发射.在这个小提琴中,每当你关闭并打开一个模态时,警报的数量也会增加(当它应该只触发一次时).http://jsfiddle.net/j36h2/1/

function openTestModal(){
    $('#testModal').modal({
        keyboard: false,
        backdrop: 'static'
    });

    $('#testModal').on('shown.bs.modal', function (e) {
        alert('');
    });
}

$('.testButton').click(function(){
    openTestModal();
});

我正在使用Bootstrap'List group ',我需要让它响应.在移动视图中表示,该列表将显示为像导航栏一样的下拉按钮.

我尝试了导航课程,但没有按预期工作.码:

<button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#side-menu-collapse">
    <span class="sr-only">Toggle navigation</span>
    <span class="icon-bar"></span>
    <span class="icon-bar"></span>
    <span class="icon-bar"></span>
</button>    
<ul class="list-group collapse navbar-collapse" id="#side-menu-collapse">
  <li class="list-group-item dropdown-toggle">Cras justo odio</li>
  <li class="list-group-item dropdown-toggle">Dapibus ac facilisis in</li>
  <li class="list-group-item dropdown-toggle">Morbi leo risus</li>
  <li class="list-group-item dropdown-toggle">Porta ac consectetur ac</li>
  <li class="list-group-item dropdown-toggle">Vestibulum at eros</li>
</ul>

手风琴必须在选中复选框时折叠.并且必须在未经检查时隐藏.

这是代码:http://jsfiddle.net/UwL5L/2/

为什么不检查？

            <div class="panel-group driving-license-settings" id="accordion">
                <div class="panel panel-default">
                    <div class="panel-heading">

                                </div>
                                <div class="checkbox">
                                    <input type="checkbox" value="">E
                                </div>                                                                                                          
                            </div>
                        </div>
                    </div>
                </div>
            </div>

我使用https://select2.github.io/examples.html,但我不想要边框半径. 如何删除边框半径以创建搜索框以及滑动区域？

我正在使用bootstrap carousel作为滑块,每张幻灯片上都有一些文字.

我希望幻灯片上的文字能够逐字出现.

我几乎解决了..

但是有两个问题

1. 在第一张幻灯片上,文字根本没有出现
2. 如果用户访问浏览器上的其他选项卡意味着当前窗口没有焦点,那么一切都搞砸了.

这是我的小提琴
